  • VMAX removed (electronic speed limiter 250km/t).
  • Alpha-N (with this the engine will run without the MAF sensors).

Importan about Alpha-n:

The MAF sensors can be left in place but needs to be unplugged.

An air temperature sensor still needs to be used - this can be either the sensor built in to the MAF sensor by leaving pins 1 (yellow/blue) and 3 (brown/orange) connected or if you will be using a carbon airbox, by connecting a intake air temperature with BMW part number  13621725323

This modification makes the engine perform the best it can in any chassis/car
