Finally we don't have to ship BMW ECUs to the other side of the world to be unlocked. It can all be done in house then straight onto the Dyno for Tuning

Our 8Y RS3 ECU Unlock + Calibration is now available. Not only are we bringing you tuning options in store and at our dealer locations we've also invested heavily in new hardware solutions that allow us to unlock the 8Y ECU in house the same day without any soldering or modification to the ECUs circuit board like some alternative options. Giving you a safe and reliable unlock and then of course a custom calibration to suit your modifications.

On average the 8Y RS3 development cars we've used have made 255kw to the wheels in factory form. This particular RS3 ended up producing 369kw to the wheels on e85 with Stage 2 hardware upgrades including intake, downpipe, intercooler & larger port injectors and a respectable 319kw to the wheels on 98 octane.

We're excited to continue developing solutions for this platform and other VAG vehicles with locked ECUs.

So close to a 9sec 1/4 mile pass but maybe next time. Pauls S3 had a great first hit out at Willowbank. With more left in the tank we'll make a few adjustments and try again. What a weapon!
With an impressive 0-100kmh time this S3 is such a weapon for a daily driven car.

Mk6 R retune

We're still doing quite a few Mk6 Rs. Surprisingly some have never been tuned but others have been recently bought and the owner isnt sure or is concerned about how the engine is running. Doing some basic checks and retuning the car gives some peace of mind its all running as it should 👌🏼

This particular Mk6 fuel pump was a bit tired so we had to run lower boost to maintain rail pressure and injection timing. The owner will eventually replace the pump and add upgraded internals and then we can add some more midrange fun for him.

Flex Fuel available now!

After years of development, we're pleased to release our Flex Fuel software for Mk7/Mk7.5 Golf R and 8V/8V.2 S3 including Stage 1, 2 and 3.

What is Flex Fuel? Flex Fuel or flexible fuel allows your vehicle to run E85, 98 Octane or a blend of the 2 fuels. The ECU seamlessly adapts to the changes in ethanol content via an ethanol/Flex Fuel sensor.

Why use E85? E85 consists of 85% ethanol and 15% premium 98 with an octane rating of approximately 107. Together with its high octane rating, cooler combustion temperatures and numerous other benefits, we're able to increase the horsepower substantially in comparison to 98 Octane fuel, especially when a higher volume turbocharger is used.

How does it work? After installing the ethanol/Flex Fuel sensor in the main fuel line, the ECU (Engine Control Unit) is able to monitor the ethanol content live and make changes to boost, ignition timing, air fuel ratio, torque control and various other performance variables to change the power and torque output of the engine.

For example, a Mk7 Golf R with our Stage 3 upgraded turbo package would make approximately at the wheels:
300kw on 98 Octane
350kw on E85
325kw on E45 (half 98 and half E85 blend)

Hardware upgrades are required to use E85, so please contact us or your local dealer to find out what is needed for your particular setup

not so slow anymore making a whopping 453kw at the wheels with a G30-770 turbo and e85. Unfortunately we maxed the current fuel system out and decided to wind it back until upgraded parts arrive
