E46 M3 3.2

AlphaN is where the air mass sensors are no longer used. Normally if they are unplugged the car will run under a reduced power mode, overfuel and bring up an engine management light with generally poor drivability. Our AlphaN upgrade is where we further develop the programme so that the S54 engine will run flawlessly without the air mass sensors. The overall smoothness of the engine is further improved over our standard ECU remap with the low speed drivability and general connectivity with the engine vastly improved.


This upgrade incorporates all of the features and benefits of the standard software above which include the power increase.

Additional Information:
There is no issue of over fuelling but it is essential that the lambda sensors are working correctly (this is essential even without AlphaN) and you keep your air filters reasonably clean (which most enthusiasts will) in order to pass emissions testing.

The MSS53/54 control uinit is fitted with a barometric pressure sensor and recieves inputs from other sensors (throttle position, lambda, intake air and coolant) to correctly calculate expected airflow and control fuelling.

Air mass sensors are used mainly for emissions purposes where manufacturers are required to setup their cars such that they will pass regulations under the most strigent conditions. For example, the cars will need to pass emissions tests before release with extremely continaminted oil with air filters which are almost blocked. Enthusiast drivers never allow such things to occur and therefore air mass sensors are not essential.

This upgrade will only be noticed upon cold start where the engine will have a higher speed by approximately 150rpm for the first 30 seconds.

AlphaN for the MSS53/54 control unit is also available in conjunction with all other features such as post cat lambda delete and custom remapping for additional upgrades as mentioned below.
