RENNtech is pleased to announce that we now offer ECU upgrades for Mark 1 (2006-2010) and Mark 2 (2010-up) Mini Coopers. Our proprietary ECU tuning software was developed in house along side our BMW Tuning program and offers significant gains in performance for both the “S” and John Cooper Works (JCW) version Mini’s making an additional 45 HP and 40 lb/ft at the crank!
By modifying ignition timing and throttle mapping, optimizing air/ fuel ratios, increasing the top speed limiter and modifying boost mapping for turbo charged vehicles; our performance software will unleashes your Mini’s true potential without sacrificing daily driver reliability. On Mark 2 Mini’s, our ECU tune can be activated with the sport button allowing you to turn up the wick anytime via the push of a button.
Paired with an Akrapovic Evolution Exhaust system and optional down pipe for an additional gain of 8 Hp and 10 lb/ft your Mini will be small in size, but huge in performance!

SARASOTA, Fla. – Imagine owning a car that attracts so much attention people jump in it and pose for pictures when you park it on the street.
A one-of-a-kind, entirely chromed-out Mercedes SL 600 could be yours.
After owning it for four years Florida businessman Doug Mansfield has decided to auction it off and donate the proceeds to organizations for the blind.
He says he was moved by an experience he had with blind children in a convenience store more than a decade ago that encouraged him to donate to the cause.
“For myself, it’s like what would it like to be blind and not to be able to see the sky and water and flowers and it’s like, they’ve got a tough life. And anything that I can do to contribute, I’d do,” he said.
The chrome convertible has a 650-horsepower twin turbo engine that can send it soaring to speeds over 200 miles-per-hour.
It will be auctioned off at the Barrett-Jackson Palm Beach Collector Car Auction in April and is expected fetch more than a quarter-million dollars.
RENNtech powered SLR once again shattered its own 1/4 mile record of 10.29 @ 134 mph (215 kmh), with an astonishing 9.76 @ 140.8 mph (226 kmh) run!
The SLR (L4P SLR 777) features full compliment of RENNtech performance and exterior modifications in addition to a full Mansory Renovatio body kit; making this SLR not only beautiful, but deadly quick. This vehicle was also the December 2011 cover vehicle of Dupont Registry and part of this years SEMA show.
The 9.76 1/4 mile time officially makes the SLR 777 not only the fastest Mercedes Benz on the planet, but also is the World’s First Mercedes Benz powered Mercedes to run 9s in the quarter mile.
RENNtech’s 2012 CLS63 broke the 11 second barrier by running the 1/4 mile in 10.98 @ 129.40 mph (208 kmh)! This officially makes it the world’s fastest CLS63.
Our latest run surpasses our previous 1/4 mile time in the same vehicle with a previous record of 11.21 @ 126 mph with only a tune and drag radials posted last month. Since then we have added a RENNtech 100% locking limited slip differential and an in development performance exhaust modification in addition to our performance ECU upgrade. The new biturbo engine now makes 688 crank horsepower and 765 lb/ft of torque; transforming the CLS63 into an all out road rocket! The vehicle made the pass in S+ (Sport Plus) and made the run from idle without launch control activated.

I love the aftermarket. They are the fringe chefs of the auto world. No content with the way something is made, they will take a classic dish-say, risotto – and then add crazy stuff to it like maple syrup and essence of deadly sea urchin. You might think, “What are you doing?? It was delicious the way it is!” But then chefRENNtech presents his 2012 Mercedes CLS63 AMG risotto and after a taste, you stop complaining. Because RENNtech has found that with a simple tune you can extract another 100 wheel horsepower. Yum.
I’m not that surprised the CLS has big power potential, because it has a big V-8 with two turbos feeding it air like it’s making foie gras. But I didn’t think you could get 100WHP out of a simple chip. AMG cars always respond well to mods, but this is ridiculous. The other day we were discussing which is a better idea, buying a CLS 550 and chipping it, or dropping significantly more money for the AMG. Well RENNtech dyno’d all of them, including a CLS63 AMG with the performance package, and one without. Check out the dyno below.
The blue line is a stock CLS63 AMG without the added Performance Package. Red line has the $7,500 Performance Package option ticked, raising power from 518HP/516tq to 550HP/590 tq. The Performance Package isn’t anything intense, it just raises boost from 14.5psi to 18.8. On the dyno, they put down 483WHP/478tq and 516WHP/544tq, respectively. So that means A, they’re both really fast and powerful and B, both are a little under-rated from the factory. Despite what your forum or 13 year old cousin has said, these cars are fast as hell. I know its 0-60 time (4.4) isn’t as fast as the Nissan R38 that had twin-supra motors and really strong guy pushing behind it, but in the real world the CLS63 AMG is fast as hell. I spent a week with one. The only place this car is slow is on the internet.
Then RENNtech starts throwing things in the pot, to satisfy crazy people like your cousin or wealthy Russians. Or wealthy anyone, really. Their chip gives the CLS a little more of the boost it craves so much, and just like that, it is putting down 583WHP and 643 torques. These aren’t gains at the crank (those numbers are 669hp/734tq. Yes, that is a “7″), this is at the wheels. You know, the part that pushes on the ground? This brings the 0-60 time down to 3.4 seconds, and the 1/4 mile is gone in 11.3s (or 11.2 with DRs).
RENNtech is proud to announce our latest line of proprietary BMW ECU tuning for late model vehicles.
RENNtech has been the foremost tuning authority on Bosch and Siemens engine control units since electronic engine management started to show up in vehicles during the mid 1980′s. Our proprietary tuning software and approach for BMW is built upon the same rock solid foundation as our Mercedes line and is completely unique and independent from our Mercedes tuning program.
RENNtech tuning software is developed and tested in house to ensure significant gains in performance and throttle response without sacrificing your daily driver BMW’s reliability. By modifying ignition timing and throttle mapping, optimizing air/ fuel ratios, increasing the top speed limiter, improving engine cooling and modifying boost mapping for turbo charged vehicles; RENNtech performance software unleashes your BMW’s true potential.
A little teaser video:
Our X5M tuning software has already generated quite a buzz and put down some pretty impressive numbers and ran the 1/4 mile in 11.99 @ 114 mph

We finally got a little cooler weather here in South Florida (high 60s – low 70s) and had the opportunity to make a few passes down the quarter mile in another 2012 RENNtech CLS63 at Palm Beach International Raceway.
To give some background, for 2012, AMG has upped the ante with the CLS63 by adding a new direct injected BiTurbo V8. The base 5.5 liter V8 Bi turbo is rated at 518 horsepower and 516 pound-feet of torque at the crank. In addition, AMG offers a “Performance Package” for those who want more. The “Performance Package” raises the boost on the turbos from 14.5 psi to 18.8 psi. As a result, horsepower jumps from 518 to 550 and torque from 516 lb-ft to 590.
We found out that Mercedes Benz was very conservative with its horsepower ratings, because on a Dynojet dynamometer at RENNtech, the new 5.5 liter V8 BiTurbo in base form made 556 horsepower and 550 ft-lbs of torque (473.24 horsepower and 468.22 ft/lbs of torque at the wheels). Note, this was the base CLS63 that is rated at 518 hp and 516 ft/lbs of torque. But this motor makes some serious power with a tune. With a RENNtech tune only, the base CLS63 made 669 horsepower and 734 ft-lbs of torque (569.13 horsepower and 624.94 ft/lbs of torque at the wheels).
Back to the dragstrip…… So, during the run in the video below, we had the opportunity to line up against a 2012 Nissan GTR. As everyone knows, not too many vehicles can hang with a Nissan GTR with its eyeball flattening 0 to 60 times. However, the big 4400 lb, 4 seater 2012 CLS63 more than held its own against Godzilla, running an amazing 11.21 @ 126.3 mph (203 kph) to the GTRs 11.11 @ 124 mph (200 kph). Enjoy.
