Now offering M2 CS Engine Tune for M3/M4 (non-CS) !

Guys,

i have successfully tested and i am now offering the CS engine tune flash for the M3 and M4.

Although it is still not possible to flash the M3/M4 CS DME, we are able to successfully flash the tune from the new M2 CS onto the M3 and M4.

This means you will get 530HP / 650Nm torque.

You will all get removal of the top speed limiter.

To answer a few questions:

What models will this work on?

This is best suited to pre-lci auto trans cars (RWD and xdrive) and LCI RWD auto cars. the LCI xdrive cars already have the same power level, but you will still get top speed limit removal. Additionally, at this point there have been many reports of increased throttle response and improved exhaust noise, which applies to all models.

What about manual transmission cars?

Manual transmission cars will not receive the CS power and will remain at your current power level. however manual cars will receive the other benefits of the CS map, including increased top speed (Vmax), improved throttle response, and increased engine sound/more aggressive exhaust flap opening.

Do i need an unlocked ECU ?

no, this is for locked DME cars.

Will it void my warranty?

it is OEM software, but not the OEM software that was made for your car. Do your research and determine your own comfort level.
