BMW M2 COMPETITION
ECU TUNING

We are able to offer a complete tuning solution for the M2 Competition ECU (including later model OPF cars) using our Ecutek software. This is the most advanced software on the market and combined with our proven calibration provides not only a huge increase performance but also a number of unique features to further enhance the car.

We have fine-tuned the calibration on both on our in-house Dyno as well as living with the setup day to day on the road with our own development cars. Combined with our various track testing sessions, we feel we have developed the ultimate software upgrades for the S55 engine. We have spent considerable time refining the throttle maps and power delivery in each gear to ensure quick but controllable progress. The power is instantly adjustable with the BMW Drive selection modes so you can quickly tailor the delivery to the environmental conditions. Even with the OPF filters and standard exhaust in place we are able to release a massive 120bhp extra with our Stage1 tune,

The new Ecutek software tool not only gives us access to all the critical maps and strategies within the ECU, but it also provides detailed logging capabilities to allow us to quickly analyse our changes and improvements. We pride ourselves on having the best calibrations available for the F-series engines but the introduction of the Ecutek software has lifted these to a whole new level. With the Ecutek software we are able to combine the best of BMWs calibration updates such as the recent CS models along with our own proven tuning adjustments. All aspects of the calibration have been refined and enhanced; from the switchable maps and adjustable Torque using the steering wheel controls to the option of live adjustments the pops and crackles from the exhaust and Per Gear performance using the smart Phone App. The software is extremely powerful and puts the driver in full control.

Our Stage 1 tune is able to take an otherwise standard car from the BMW’s claimed 404bhp and 405lbft to 520bhp with 510lbft with a smooth and predictable power delivery.

Our S55 ECU remaps now feature our latest RACEROM setup which gives you even more control over the cars performance as you can set it up to suit your driving style. Our remaps include a completely new calibration that allows the S55 engine to provide significant increases in power and torque over the standard engine as well as adding some unique features.



Switchable maps

Our default settings which you can change instantly using the Cruise Control buttons are:


  • Map1 95 Octane normal unleaded fuel which will produce around 500bhp and 485lbft (Stage 1)
  • Map2 97/99 Octane Super unleaded fuel which will produce around 520bhp with over 510lbft (Stage 1)

The RACEROM patch also remembers which map you were in when the engine is switched off so if you always run on Super unleaded it won’t need to be changed.

We utilise the Cruise Control buttons while the Cruise is turned off but when you switch Cruise Control back on again the buttons work as normal so you lose no functionality. The software allows for upto 4 separate map slots so let us know if you a specific requirements such as Race fuel use.



Adjustable Torque

This feature lets the driver instantly adjust the torque the engine produces using the steering wheel controls. This is represented on the Driver information display gauges so it is straight forward to select anything from 50-100% of maximum torque. It also changes the percentage of torque being applied to the per gear torque selection so if you have this setup individually and want to reduce torque by 30% it will also apply this same 30% reduction per gear. Ideal for quick changes if the weather turns during on a trackday as you want to do more than just adjust drop the peak torque value as each gear will require this to set differently.



Recalibrated Driver Display

All our remaps include recalibrating the Driver Display to show the engines new power and torque figures.



Vmax removed

All our remaps include removing the top speed limiter so drivers can choose to driver over 155mph on de-restricted Motorways or on track events.


Custom exhaust valve control

All our remaps include adjusting the exhaust valve to give a better exhaust note and reduce drone when cruising.  Especially useful for cars with performance exhaust or downpipes.



Optional Cold Start removal

We can simply remove the Cold Start process that causes the engine/exhaust make a loud unpleasant noise while the ECU tries to warm up the CATs for emissions.  This can become extremely loud on cars with no CATs installed.



Adjustable Pops & Bangs/Burbles

– Requires Bluetooth interface and Phone App


All our remaps have the burble setup similar to the GTS/CS models so it gives a nice sound when in Sports mode. However this can be adjusted using our Phone App to suit each driver’s needs. The simple slider can make the burbles more aggressive of switched off completely.



Adjustable Torque Per Gear

- Requires Bluetooth Interface and Phone App


Within the Phone App the driver is able to easily adjust the amount of torque going to the wheels using a simple slider. We have setup a good default setting for the first 3 gears but now the driver can request more or less torque in 1st, 2nd, 3rd and 4th onwards. This is ideal if you are on a slippery surface, have gripper tyres as few quick changes can really improve the traction and enjoyment of the car.



Optional Ecutek Bluetooth Interface and ECU Connect Phone App

Ecutek’s Bluetooth interface is available now and works seamlessly with the BMW S55 engine in the M2 Competition, M3 and M4 models and allows the driver’s phone to communicate with the car using Ecutek’s free ECU Connect Phone App.

Along with the additional custom maps we highlighted above the ECU Connect setup has a host of other useful features that can be used on most OBD compatible cars (1996+).

  • High Speed Data logging – Display and record factory and RaceROM diagnostic parameters.
  • RaceROM integration – Driver interaction with RaceROM features.
  • Read & clear DTCs.
  • Dashboards – Display real-time data from any parameter in a set of graphical displays using circular gauges, bar graphs or text.
  • Performance analyser – Test and share the performance results online.
  • Archive – Stores log files and performance test results for sharing directly from within the app.
  • ECU info – Provides detailed information about the vehicle concerned.

The Bluetooth interface is in stock now and costs £180 inc. VAT and the phone App is free to download the Apple App Store or the Android Store.



Flex Fuel integration

For customers looking for the ultimate performance we are also able to offer an integrated Flex Fuel system which works with the OE ECU and automatically adjust the performance based on the ethanol content in the fuel tank.

Stage 1 ECU tuning - 520 bhp & 510lbft



Tuning the M2 Competition ECU with the Ecutek software allows us greater control of the ECU and as such provides 520bhp. We've fine-tuned the calibration for both on our in-house Dyno as well as living with the setup day to day on the road with our own development cars. Combined with our various track testing sessions, we feel we have developed the ultimate software upgrades.

Whilst the engine and ECU may be the same as the F8x M3/M4 (albeit with slightly reduced power) there has been some drastic changes to the exhaust system. The release of the M2 Competition also saw the introduction of the new OPF filters in the exhaust. These dense particulate filters form a significant restriction in the exhaust so careful tuning is needed to limit excess back pressure and stress on the engine.

The Ecutek software tool not only gives us access to all the critical maps and strategies within the ECU, but it also provides detailed logging capabilities to allow us to quickly analyse our changes and improvements. We pride ourselves on having the best calibrations available for the F-series engines but the introduction of the Ecutek software has lifted these to a whole new level. With the Ecutek software we are able to combine the best of BMW calibration updates such as the recent CS and GTS models along with our own proven tuning adjustments. All aspects of the calibration have been refined; from the adjustable pops and crackles out of the exhaust, to the recalibrated power dials on the centre screen. We have spent considerable time refining the throttle maps and power delivery in each gear to ensure quick but controllable progress.  We put the power in the drivers hands with instantly adjustable maximum Torque settings that work in conjunction with the BMW Drive selection modes so you can quickly tailor the delivery to the environmental conditions. Even with the OPF filters and standard exhaust in place we are able to release a massive 90bhp extra with our standard tune, with power increasing to around 520bhp, with the Ecutek developed tune. Torque increases smoothly  to over 510lbft and is available from low in the rev range to provide huge increases.

Each car that comes in will also have the engine management system checked and updated to the latest BMW software version.

* Late model BMW M2 Competition models have the latest BMW ECU firmware installed at the factory (~March 2019) or may have been subject to a Main Dealer firmware update. This new firmware version removes the loophole that allows direct programming through the OBD port. We are able to simply reverse this to allowing OBD programming, but we do require the car or ECU to be present so we plug in and unlock it (no opening is required). Once completed we can continue to tune remotely as before.

Stage 2 ECU tuning - 540 bhp & 520 lbft



Our Stage 2 upgrade uses a performance downpipe CAT back exhaust system to allow the engine to breathe more easily and comes with our Ecutek delivered Stage 2 ECU calibration to increase power and noise.

The release of the M2 Competition also saw the introduction of the new OPF filters in the exhaust. These dense particulate filters form a significant restriction in the exhaust so careful tuning is needed to limit excess back pressure and stress on the engine. For this reason many customer choose to change the exhaust to a free flowing design to improve both the performance and the sound quality.

If the car does not already have our Crank Hub Fix installed we would need install this prior to completing this work. For more information on this known problem and our options for fixing it, please read our blog post BMW F8x M3,M4 & M2 Competition Crank Hub Issue.
