Berk Technology left hungry after Road Atlanta

FOR IMMEDIATE RELEASE - Santa Ana, CA, May 14, 2013.

Despite tasty southern food such as served at Cracker Barrel and Waffle House, the Berk Technology team left Road Atlanta, GA, hungry – for foothold in Formula Drift Top 32. On the undulated Road Atlanta course, by the time of qualifying the Rydquist Racing / Berk Technology / City Tire powered by Champion Nissan 350Z gearbox took a stand with a ruined 3rd gear synchro ring, disarming driver Carl Rydquist when needed the most.

“It’s a shame.  I just recently said in an interview that a dogbox is at the top of my upgrade list but we haven’t had a chance to get that done.” Carl says and continues, “The 2nd-3rd quick upshift is done in the easiest part of the entire Road Atlanta course, but it has to go quick. When the 3rd gear synchro wears out, the gearbox needs almost a second to allow the rpms to drop for the gear to go in. That is enough of a pause that the car straightens out with the fast chassis setup we were running.  Very disappointing.”

On a so called dogbox, a special type of racing specific gearbox, this type of malfunction cannot occur since there are no synchros. A dogbox is specifically designed for immediate/quick gear changes.

On a positive note the Rydquist Racing / Berk Technology team were able to get an idea of the positive impact of their new rear suspension design, with the car launching much quicker off the line and having more forward traction on the course.


“The car seemed more competitive”, Berk Technology owner Bryan Min explains. “We never got to see the full story, missing out on Top 32, but it was clear that when launching from the lights Carl was now able to get the venerable Hankook Ventus R-S3 tires to hook up and keep a much more constant distance to the cars that at Long Beach were leaving us in the dust off the line. “

The Road Atlanta Formula Drift event was jam packed with dedicated fans, many of whom stopped by the team’s pit area to check out the Rydquist Racing / Berk Technology / City Tire powered by Champion Nissan 350Z, talk to the team and become fans.


“The Atlanta fans are always the greatest bunch”, Carl says. “The same goes for all of what we saw in Georgia, it’s such a friendly atmosphere here. I can’t wait to return next year.”

Not wasting any time, the team immediately went to work and prepared the car for the next competition.

“We added front end stance to match the increased rear grip, and wider stance allows for more steering angle”, Carl explains. “We’re also catching up by taking care of a so far less than perfect power-steering, I am very excited to get that fixed because it gives me the freedom to drive the car more precisely. Until now it's been a handful, and I have been barely able to move the steering wheel when entering low speed turns, something that's very important when you want to drift with authority.”

The Rydquist Racing / Berk Technology Nissan 350Z is scheduled for a substantial engine power upgrade upon its return from the remaining East Coast events (Florida and New Jersey).

The third round of the 2013 Formula Drift PRO Championship will take place in Palm Beach, Florida on May 31- June 1. Tickets can be purchased online at www.formulad.com, and news, livestream and all event info can also be found there.

Me and my AEM - Part 1
Tuesday, May 7, 2013

Me and my AEM, part 1 – by Carl Rydquist

This is the first segment of the AEM write-ups that I will be doing this year. AEM engine management systems have a lot of nice features that I have yet to tap into fully and as my Formula Drift season continues on and I get to explore and utilize more of the power within the AEM Series 2 EMS that I am using, I will add write-ups here.

1. Choosing the right engine management system

Building a drift car or race car is fun but it also involves a lot of decisions and challenges. The key, at least in my opinion, is to set a high target early, in terms of what performance the car is supposed to deliver. Set it too low and you will find yourself doing tedious re-work down the road once you are ready for the next step and the lower cost parts you first went with will now have to be replaced by upgraded parts and suddenly you are roughly “1,5 purchase“ into a solution instead of doing it right from the beginning and going for the good stuff from the get go. Loosely comparing this to the OEM world, this way if thinking is called “first time right” and FTR is something everyone strives for on a daily basis and tons of time and processes are put in place to create robust and people independent results , simply because re-work is the most expensive form of development.

So going for the good stuff from the outset was the reason I finally decided to go with AEM. I have to admit that I was very deeply into research of different solutions, simply because some options on the surface seemed to initially be able to cut some time in the build process, and time is money right? But in the end it was in the details and I consulted some very talented people, studied up and double checked everything from processor capacity and tune table resolution of the systems I was looking at, because in the end, I am an engineer and good or bad, I like to connect statements with data before I decide.


The AEM Tuner software is very user friendly and divided into tabs for fuel maps, ignition maps, actuators, sensors, etc.

The REAL technical advantage is what I wanted in the long run. That means not being swayed by how easy a reasonably technical person can possibly set an ECU solution up by herself/himself for the first time to run a motor on idle, but the hard facts such as how well the ECU will actually perform and manage my engine under high stress conditions, when it really matters. This is what made me choose AEM. I wanted the most flexibility and serious processing power combined with high resolution tuning tables. Doesn’t hurt either that the AEM Series 2 also has a built in boost controller! First Time Right, remember?

The project car I had bought had some positives, and some drawbacks. Positive was that it was already gutted and minimalistic in the wiring department, making life less confusing and less restricting than a full OEM harness. Basically a rolling shell. The negative was… well there was essentially no wiring, or actually, the wiring left in the shell was not useful to me. It was old and taped, and re-taped, and grimy with oil and a couple of years worth of shop dust, and it was hard to imagine that it would work reliably under “hot conditions”. So the harness had to go. No harness means blank canvas. Also means that a lot of great, well proven OEM features and diagnostics were gone with it...


Lucky for me and other people in my position, the AEM Series 2 Engine Management System is able to provide extremely useful features that can substitute much of the OEM useful on board diagnostics. This stuff is so important, and interesting that it will get its own complete chapter (3).

2. Making it work

Without any harness to talk about, the AEM Series 2 would have to be the main brain of my car, meaning no piggyback solution off of the stock ECU. To make the Series 2 run standalone is a different procedure for every car, the newer the car the more adjustments will usually have to be done, because OEMs use elaborate and very brilliant systems that often are built with redundancies and that are constantly monitored by plausibility checks. If these sytems are interrupted, they will either not work, or will throw fits such as limp home mode, or only work partially.

The VQ35DE is pretty straightforward though and one of the few things to change was that on the VQ35DE the electronic throttle body had to be converted to a cable throttle body, not because AEM doesn't handle drive by wire throttle body control, it has just not been implemented into the S2 for the VQ35DE. The AEM Infinity Series however can by now control dual Drive By Wire throttle bodies though – development moves along quickly!).

One downside for me to not have electronic throttle body control is that you cannot do like some OEMs do on their modern turbo cars, close the throttle automatically in case of overboost etc, but luckily there are options in the AEM Series 2 that can help prevent overboost in different ways (such as ignition cut at a specific, user chosen boost value).

Another example when running fully standalone was modification to the peculiar camshaft teeth on the VQ35DE, in order to make use of the variable cam timing feature in the AEM S2. Modifying the cam teeth was a small price to pay though for the significant advantage of having active and working variable cam timing (another note here, AEM Infinity has been further developed for the VQ35DE application and is now able to handle variable cam timing without modification of the cams).

Wiring wise, in theory this is a pretty straightforward with the OEM ECU is gone. The circuit diagram for the AEM Series 2 EMS is easy to read and essentially you plug in ground, 12V feed, all the sensors you plan to use, each to their channel/pin and then add your boost solenoid and you are pretty much ready to start working on the calibration and fire up, tune and go. In reality it takes patience, patience, a lot of checking and double checking, and more patience, and knowledge. It is very wise to consult an expert for these types of jobs, because an expert has seen it all before, knows what needs to be done, and will get it done.
Mitch Pederson / MP Tuning applying his science on the Rydquist Racing Nissan 350Z. It is a huge boost for anyone to hire an expert for making it all play together.

In my first step, and here I am looking at wiring rework… I had an engine that already had a factory engine harness on it. Easy enough with everything already connected, just plug in and go, right? Well I can tell you that probably there are less than 10 wires out of 50 that are left stock. Everything else we have had to change, from air intake sensor, adding boost solenoid instead of throttle body control, re-wired crank and cam sensors, injector connectors are different… the list goes on. Not because of the AEM S2 but because I use different injectors and sensors than OEM. So essentially, learn from me here and do what I pushed off, have someone build a proper harness. My plan was, still is, to get a proper harness built when I pull this engine out and install a seriously built engine. But had I had the chance to do it again, I would have had a full on proper harness built already, even for this first mildly tuned engine I am using at this moment.
At the (former) SR Tuning dyno, hearing it really sing for the first time.

Old harness or not, in my case Mitch Pederson/MP Tuning set my AEM ECU up in literally no time, and whenever there was a challenge with a bad sensor signal or something like a generator that wasn’t charging, he knew what needed to be re-wired or altered to get to the right results, immediately. Without MP Tuning, I would not have made it to Formula Drift Long Beach.

3.       Diagnostics


Before going into diagnostics, a short note about the datalogging capabilities of the AEM Series 2. I can't go too deep into this yet since I haven’t had it for long enough, and basically in the AEM Series 2 it’s only really intended for engine management and calibration, rather than datalogging as it is known in road racing. Still, the AEM S2 has a 1Mb memory which when you are only storing columns of data, is actually quite a bit and if you choose reasonable sample rates you can actually log for quite a long time (20-30 min is no problem and this covers most session lengths).

The really helpful features though when being at the track and having a potential problem is the ability to use the AEM Tuner software with the laptop hooked up to the ECU and being able to run through a series of checks of everything and eliminate potential issues step by step until the problem is narrowed down.

  
All sensor windows under one tab, and the curves can be aligned/calibrated depending on the sensor output curve, allowing perfect matching between sensor and used values (visual or internal).

I’m going to offer some candid insight here, I had a bit of a challenge right around tech time just before Formula Drift Long Beach because we had done some heavy work on the car leading up to the event and we had missed a very basic item when putting the car back together – this stuff easily happens by the way when several people work on several things on the car at the same time, and you grind through the night until early morning.

So the car was in the FD garage at Long Beach and it wouldn’t fire up. It had fired up when loading, it fired up loading off, and I had had no less than three test days without any issue to start the engine. But when trying to start for our turn on the Tech ramp it refused to fire up. “Dentist scare symptom?”

I plugged in the laptop and launched the AEM Tuner software and started from the ground up to look at the basics. I had seen Mitch go through this routine before the first fire up, but obviously I wasn’t able to remember each and every detail of it. I got him on the phone and he filled in the gaps and walked me through some pretty cool custom output setups in order to cover all the bases. One specific example was that I could control one injector at a time via the gas pedal to hear each one open and close to make sure they weren’t stuck – tech nerdy all the way but oh so cool when you are in a time crunch and have a professional drift event right about to happen. This is just one little example, out of hundreds of cool trigger/actuator combinations that can be programmed via the AEM Tuner software - many of which can be set as failsafe or performance optimizers when certain conditions are met.
Photo: D. Karey

In the end we were able to establish that there were no issues with coils or spark, no issues with crank and cam sensors, no issue with fuel pressure or plenum or intake air temp or throttle position sensors, no issues with injectors, and nothing else noticeable in the ECU. Leaving what? Had to be something substantial. Like a missing ground cable. Getting under the hood for the 10th time, I found one end of the engine ground cable harness not attached. It sat close to the frame rail but wasn’t bolted on. It had moved off the rail when the car came off the trailer which is why it would not restart. I bolted the ground wire back onto the frame rail and the car fired up instantly. A missing ground is a truly basic mistake, but as I said, 5am in the morning after 10 straight hours of hard work with many different pairs of hands on the car, those things do happen.

I sleep a lot better these days knowing that with the AEM Tuner software I can simply go sit in the Sparco seat of my racecar with a laptop connected to the AEM S2, and then I can run a 10-15 minute diagnose to check if my Engine Management System is truly happy and that all conditions are met to fire up the engine, or if there is a specific wiring or sensor issue causing a no-start condition.
This is how happy I am to be able to trouble shoot my car through the AEM S2.

Once you get the hang of these kinds of basics of advanced engine management systems such as the AEM Series 2, complexity transforms into simplicity, and you are more likely to be on the starting line on time than not.

Berk Technology improvements to be tested and tried at Road Atlanta
Friday, May 3, 2013
FOR IMMEDIATE RELEASE - Santa Ana, CA, May 3, 2013.

Berk Technology improvements to be tested and tried at Road Atlanta

Moving forward on the momentum from the 2013 Formula Drift PRO Championship season premiere at the Long Beach Grand Prix circuit, Berk Technology has finished a short but intense period of developments to the Rydquist/Berk/City Tire powered by Champion Nissan 350Z and the team has finally sent it off to drift in the second Formula Drift PRO Championship round at Road Atlanta next week.

The team implemented a first few of many planned changes to the car, one being a very basic fix; at Long Beach, Carl Rydquist had to drift with a too short final gear ratio with almost 20mph less wheel speed than desired in 3rd gear.

“This is really the basics, and I had planned a much longer gear ratio but we ran into a last minute unexpected problem that created a domino effect of adjustments we had to do”, Carl says. “In the end the shorter ratio I ended up using caused some lost style points in qualifying and the non-optimal traction was painfully clear  during my top 32 tandem battle where I lost approximately 4 car lengths off the launch to the lead car already into the first turn. It’s not always about power itself but also about being able to put it down to the  round“.


“We immediately went to work to update the 350Z suspension geometry. Formula Drift has very specific rules regarding the extent of changes that are allowed and we based our work on those rules”, Berk Technology owner and crew chief Bryan explains. “The goal was simple, increase suspension geometry consistency and increase traction. Exactly what we did is a speed secret, let’s first see how it works”.
   
Road Atlanta is expected to become an incredibly competitive event and the Rydquist Racing / Berk Technolgoy team is hoping that these crucial chassis changes will help move them up the field.

All improvements are evaluated and analyzed in detail by Rydquist and the Berk team, then tested and hopefully proven at the track.

“I am super excited about these specific changes that we just did and I am equal amounts impressed with and proud of the amazing work that Berk did on the suspension, I can’t wait to drive it”, Carl says. “Working with Berk Technology, there is always something we discuss in order to improve the car”.
The Rydquist Racing / Berk Technology / City Tire powered by Champion Sparkplugs 350Z will sport new Spyder headlights and taillights for Road Atlanta. Stay tuned for cool footage!

At the Road Atlanta event, Rydquist Racing / Berk Technology will collaborate closer with fellow Formula Drift  driver Jhonattan Castro and City Tire Online, who is competing with their Progreso / City Tire / Hankook Nissan 350Z. This is the car that Rydquist was competing in Formula Drift with during 2009.

“In this case City Tire is family to me so the collaboration will be fun and a great experience. Jhonattan is also a really nice driver to be around and we are always trying to help eachother and share setup data when we can”, Carl explains. “I will definitely miss the large Berk crowd, but at the remote events we can only bring the core of the Berk team and instead increase the collaboration and share resources with another team to find efficiencies”.

Rydquist had a solid showing at Long Beach with the newly rebuilt car, coming back to Formula Drift after a 3 year long detour to different Time Attack races and racing in major around-the-clock races such as the 24 Hours of Nuerburgring, Barcelona and the 25 Hours of Thunderhill.

“I know we have a few limitations until we have developed the car a bit more, but we just have to stay focused and work systematically on the car and on my driving”, Carl says. That we made Top 32 already at Long Beach was a huge reward and boost for the team, I really hope we can repeat and be even more competitive at Road Atlanta”.

“Competition is not going to get any easier”, Bryan Min adds in. “If you look at the top 29 names, they are all FD veterans more or less, and some of the top guys were out with mechanical issues at Long Beach. If everyone runs well, the fight for a Top 32 spot will be incredibly hard. We have to focus and prepare better than ever, to claim our ground and move forward from there”.

The second round of the 2013 Formula Drift PRO Championship is set to take place on May 10-11 at Road Atlanta near Braselton, GA. Tickets can be purchased online at www.formulad.com, and news, livestream and all event info can also be found there.

Berk Technology’s Maiden Formula Drift Event a Success

Berk Technology’s Maiden Formula Drift Event a Success

FOR IMMEDIATE RELEASE - Santa Ana, CA, April 14 2013.

2013 saw Berk Technology steer their motorsport activities in a completely new direction; professional drifting. With team driver Carl Rydquist and his Champion sponsored Rydquist Racing Nissan 350Z, Berk Technology joined the 10th season of the Formula DRIFT Pro Championship at the Round 1 season premiere held at the Streets of Long Beach.


With over 60 drivers present, many of whom are factory backed teams, reaching the main event competition (Top 32) is an accomplishment on its own.  By diligent car preparation, combined with focused testing and setup, Rydquist was able to navigate the challenging Indy Car course laid out by the Formula DRIFT judges with a score high enough to win a Top 32 spot during Friday’s qualifying session. 
  
Entering the Top 32 elimination rounds, Rydquist faced 4th place qualifier and eventual 4th place finisher Chelsea DeNofa.  Despite Carl’s attempts to make up for a large horsepower deficit with his “go fast” racing skills, a Top 16 advancement will have to remain on the team’s to-do list for a future Formula Drift round.
The Rydquist Racing / Berk Technology Nissan 350Z Turbo utilizes an AEM S2 standalone ECU that allows full control of the Garrett GTX turbocharger, which up until now, has been running low boost. The team will now focus on suspension geometry optimization and upgrades of the engine internals, to be able to extract the full power potential available and to put the added power to the ground utilizing the venerable Hankook Ventus R-S3 tires.  
  
“We are proud of such a great result at our very first professional Formula Drift event.  It has been a pleasure working with Formula Drift as an organization with their professionalism and global marketing reach.  We are excited to be a part of the series and the impact Formula Drift will bring to our team and partners.” – Bryan Min – Berk Technology Inc.



“I am overjoyed with how the car ran, and how I felt out there. It was nothing like when I entered as a rookie in 2009. The car setup was flawless and to slide like a pinball, just barely avoiding the walls, was simply a super thrill. Berk Technology, true to their core values, helped build and prepare a flawless car. I cannot wait to get into the seat again at the next event”.  – Carl Rydquist
  
The Formula DRIFT Pro Championship will now head into its east coast stint with the next event being “Road to the Championship” on May 10-11 at Road Atlanta, GA. 
  
The Rydquist Racing / Berk Technology / City Tire collab would like to extend a THANK YOU to each partner for the support that provided a platform to step into professional drifting with this successful result at Long Beach!

Shakedown and testing
Sunday, March 31, 2013

Been out to Willow Springs a couple of times in the last few weeks, to shake down the car after building it up again from being a barely rolling shell.

Shakedown went well, first impression of the car was that it's very easy to control. No leaks or other major issues noticeable except low power steering assist in low rpms.



The test day started out totally different, the track had much more grip and the setup was totally off, following suspension hardware changes, and the car had totally different ride-height and alignment as well that didn't help. Essentially I had to drive it way over-aggressive to make it drift and once in drift, it would be super snappy and all together it was very difficult to control above 2nd gear drifting, so we went straight to work on the suspension.

During the day, Berk Technology crew guy Artin (ANB) and I worked a lot on the setup, did a multitude of changes on almost every part of the suspension and aero and I was in and out from pits to track constantly.

Towards the second half of the testing the setup was starting to get good, and I got several good runs for my own driving development as well, and I could bring more attack and flick the car from full lock one way, to full lock the other way repeatedly, and control my lines more by throttle again. I went from feeling pretty "surprised" at the difficulties in the morning, to feeling very positive about the car and about getting my own driving in the zone again.

Now a few items are to be updated back at the Berk Technology shop to improve performance ahead of the Formula Drift season opener in Long Beach (final drive ratio, power steering, ACT clutch+light weight flywheel, oil drain from the Garrett turbocharger) and my next test day we will work on the setup to be able to run with maxed out steering angle and light up the Hankook Ventus R-S3 tires as much as possible.

Snow White back from paint.
Friday, March 1, 2013
Just got my ride back from the paint shop last night. John @CityTireOnline came over with a trailer to give me a hand to get "Snow White" back to the shop. The bodyshop guys lead by Ozzie did a great job in a very short time, and the car is now super white, which is a popping white color begging for some cool color wheels and some nice vinyl accents. It's almost been a week since Mitch at MP Tuning did the engine calibration on SR Motorcars dyno so it was extremely fun to fire it up again and hear and feel the engine. The  Berk Technology custom exhaust really sounds responsive.

Got a couple of minor tasks such as belts and battery bracket but then Super White is good to go for shakedown. Can't wait!
