OEM+ ECU & TCU Software Package – Audi S5

ECU Calibrations

Unique Approach
It’s by reprogramming the very basis of the controller itself that we achieve the results we get – just as the manufacturers themselves work.

Great Performance
By starting from scratch for each calibration, OEM+ achieves a very different level of performance and drivability. It’s never just about winding up the peak power.

Peace Of Mind
We are uniquely positioned to tap into a vast knowledge base and resources network in our development. And we’re confident enough that you’ll love it that we offer a 30 day full money-back guarantee.

Matched To Hardware
No other brand can offer you such a comprehensive ‘full-car’ tuning solution. Our Performance Parts range is the most complete on the market, all matched perfectly to the OEM+ software.

Upgrades For Life
Free upgrades on your car for as long as you own it. Start with OEM+ Stage 1, then we will give you Stage 2 and even Stage 3 Performance Software for free!

Return To Stock
Should you ever want to return your car to standard, the OEM+ system has the facility to return your ECU to ‘True Stock’, the exact state it was in prior to installation of OEM+ tuning.

RacingLine has been developing high quality performance hardware parts for race and road cars for nearly two decades – firmly establishing ourselves as the hardware brand of choice for Volkswagen Group vehicles. But we aren?t stopping there.

We have been working flat out over the past two years to develop our OEM+ Performance Software. We believe it to be simply the best ECU Software Upgrades and TCU DSG Transmission Software in the market, conceived from a very different approach. By bringing together a full suite of carefully developed software, all matched to work in perfect harmony with our ever-growing range of hardware, we truly believe that RacingLine Performance can offer customers the most complete range of upgrades for their VWG car.

TCU Calibrations

OEM+ TCU Dynamic Software & Tuning is simply an essential upgrade to get the most out of any modified DSG car.

Several years of road and track development have given us the smartest transmission software on the market: by continually feeding the engine ECU?s torque demands through to the gearbox?s controller, the system dynamically calculates and adjusts the DSG?s variable clutch pressures to suit whatever your power output is.

Meaning that just one RacingLine TCU software upgrade will serve your car from standard, through Stage 1, right up to Stage 3 and beyond. So unlike some, there’s no need for a new TCU calibration each time you increase your car?s performance.

Our engineers reprogram the gearbox’s calibration inside the TCU (Transmission Control Unit). This allows the transmission to maintain higher torque levels through our dynamic clutch pressure strategy, right up to a mighty 19 bar pressure. The result? Shifts are even faster, giving harder acceleration through the gears, whatever level of performance your car has – up to & beyond Stage 3.

Meanwhile, the driving mode strategy itself is optimised to suit higher power levels, giving a more natural gear selection profile. Flick the car over to manual, and at last you’ll have true gear control at your fingertips – no auto-upshift*, no kick down until you command it (or drop back to D/S modes).
Not only that, launch control will get you off the line quicker through allowing more boost at launch and increased launch RPM, combined with a less intrusive traction control in launch mode.

* auto-upshift disable not available on certain gearbox codes
