The RENNtech ECU upgrade is the ultimate tune for the BMW X5/X6M! Our tune allows the SUV to run an astonishing 11.99 @ 114.05 mph in the quarter mile. Our ECU also alows the M SUV to accelerate from 0-60 mph in 3.75 seconds and 0-100 mph in a mere 9.2 seconds!
Our proprietary BMW ECU upgrade offers rock solid performance from RENNtech, the foremost tuning authority on Bosch and Siemens engine control units.
These same units are utilized in Mercedes Benz vehicles, which RENNtech has been tuning since electronic engine management started to show up in vehicles during the mid 1980′s, though our proprietary tuning software and approach for BMW is completely unique and independent from our Mercedes tuning program.
RENNtech tuning software for BMW offers 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.

RENNtech, one of the premiere Mercedes tuners in the world, recently strapped a new 2012 Mercedes CLS63 V8 BiTurbo to their dyno and the results are impressive. For background, Mercedes Benz has dropped the CLS63′s naturally aspirated 6.2 liter V8 engine (rated at 507 hp and 465 lb-ft) that debuted in 2007 in favor of a smaller 5.5 liter BiTurbo V8. Although the outgoing 6.2 was a high winder, we longed for the torque of the 5.4 liter Kompressor motor (E55, S55, SL55, CL55) the 6.2 replaced.
Well, our performance prayers have been answered. The new direct injected BiTurbo V8 is STRONG as the dyno result below confirm. The base 5.5 liter V8 Bi turbo is rated at 518 horsepower and 516 pound-feet of torque at the crank. 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.
Mercedes is generally conservative with its power figures, and the dyno numbers confirm that they did it again with the new CLS63. 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. In sum, the new CLS63 made approximately 40 horsepower and 40 ft/lbs of torque more than the factory claims. But hold on, this motor makes some serious power with a RENNtech tune. Hartmut Feyhl and his team at RENNtech have spent untold man hours doing research and development on the new 5.5 liter BiTurbo. As a result, they have developed a tune that is nothing short of astonishing. With a tune only, the same 2012 CLS63 made 669 horsepower and 734 ft-lbs of torque (569.13 horsepower and 624.94 ft/lbs of torque at the wheels). That, my friends, is huge power. The CLS63 power numbers with RENNtech’s proprietary tune are in the territory of Mercedes’ $300,000 V12 BiTurbo SL65 Black Series.

According to Mercedes, the new 2012 CLS63 equipped with AMG’s seven-speed “Speedshift” MCT transmission will rip from 0 – 60 mph in 4.4 seconds with the lower boost motor. The “AMG Performance Package” cuts a tenth and gets to 60 mph in 4.3 seconds. Top speed also goes up from 155 to 186 mph with the AMG Performance Package. We believe these numbers are conservative as well since we are aware that the 2012 CLS63 will run the quarter mile (stock) in 12.0 at 122 mph.
With the RENNtech modifications pushing the power to almost 670 horsepower and 740 ft/lbs of torque, it is safe to assume that the new CLS63 will run the quarter mile in the low 11s at close to 130 mph. As soon as we can get the new CLS63 to the drag strip, we’ll post the performance results.
RENNTECH MODIFIED 997.2 DFI TURBO FEATURING OUR PROPRIETARY PERFORMANCE ECU TUNING SOFTWARE AND AKRAPOVIC TITANIUM EXHAUST SYSTEM. THIS TURBO WAS DELIVERED TO US WITH AN AFTERMARKET EXHAUST AND ECU TUNE ALREADY INSTALLED, SO THE BASE LINE RUN SHOWN IS WITH THESE COMPONENTS INSTALLED. AFTER REPLACING THE EXHAUST AND INSTALLING OUR SOFTWARE, THE COMBINATION PUT DOWN 500 WHP AND 487 LB/FT TORQUE.
RENNtech is proud to introduce our performance exhaust system featuring secondary catalytic bypass pipes and rear x-pipe for the new Mercedes SLS AMG. Our exhaust produces an intoxicating growl at idle and incredible exhaust note under load. In conjunction with our proprietary ECU tuning software, our exhaust unleashes the beast lurking underneath the SLS’s refined exterior.

While the CLK Black series is already a potent and capable vehicle straight off the showroom floor, this particular CLK Black Series came to RENNTECH in search of more. Sometimes you just truly can’t have enough of a good thing. With this in mind, RENNTECH delivered the goods and installed our proprietary ECU tuning, RENNTECH sound and performance exhaust piping, performed a performance suspension adjustment and vehicle lowering with 20mm wheel spacers to fill out the fender wells and increase vehicle track.
These modifications gave the CLK a more fitting hunkered down, aggressive appearance while the ECU tune and exhaust gave this Black Series the sound and performance to match its looks. Here are some before and after pictures of the vehicle as well as a video clip of the RENNTECH performance exhaust.

RENNtech is making progress on one of this year’s most sought-after supercars, the Mercedes-Benz SL65 Black Series. Initial ECU programming results on the twin-turbo V12 were remarkable. And after further testing and development RENNtech massaged 630 HP / 765 LB-FT at the wheels on the in-house dyno. In the case of this particular dyno run that’s 67HP/69LB-FT over stock. Helping to plant that tire-liquifying power to the ground is a custom 100% locking limited-slip differential.
RENNtech will continue to pump up the SL65 Black Series and expects to have even more substantial numbers as R&D progresses. Stay tuned!
RENNtech has introduced a new revolutionary Auto Tuner for Mercedes-Benz vehicles. For the first time, you can reprogram your ECU simply by plugging in the new R.A.T. (RENNtech Auto Tuner). No need to remove the ECU!! Once the reprogramming is complete (about 90 seconds), you can easily switch between stock, for street use, and tuned, for the track, with the flick of a switch.
The R.A.T. is shipped out preprogrammed with RENNtech’s list of firmware and can be sent anywhere in the world. When first plugged into your Mercedes-Benz via the OBD II port, the tuner “marries” itself and uploads the proper file. If the proper file is not already available or you would like to have a custom file made, simply plug the R.A.T. into your computer. The vehicle data is sent to RENNtech and, after being tested, your new file is emailed back to you. If you lose power or the R.A.T. is disconnected while uploading the file, the tuner is designed to automatically recover the stock programming.
The R.A.T. is available for the Mercedes-Benz E55 and 2006, or earlier, Mercedes V12 Turbos. See our website for more info.
RENNTECH’s new $3995 performance PKG1 for the 05-08 SLK 350 boosts the output of the 268 hp V6 to over 300 hp. That’s 40 horsepower for under $4000!
This level of performance and torque comes from new RENNTECH headers and a RENNTECH ECU upgrade, which also raises the car’s top speed from the factory-limited 155 mph to over 170 mph. As the copy above states: this package will change the way you look at Mercedes’ 350 series cars.
RENNTECH’s new ECU upgrade for Smart Fortwo improves the Smart’s power (to 74 hp) and throttle response across the rpm range for better acceleration and noticeably improved shifting. Top speed limiter is removed.
