BMW M3 (E46) ECU TUNING

Litchfield ECU Calibration



We have developed an improved ECU calibration for the 3.2 litre M3 engine with both standard and Evo engines in our fleet. This recalibration enhances both power and driveability. Based on the BMW’s latest M3 calibration we can provide owners with an upgrade that will release around 15 bhp over the original tune and provide a crisper throttle response. Our software also removes the internal speed limiter.

Litchfield ECU Alpha N Calibration



For customer looking for more power we are able to offer our Alpha N calibration. This is designed for cars running full exhaust systems and the CSL style intake manifold and we tune the car using the MAP sensor as the load input. This can see power levels rise to around 360 bhp.
