  1. Converting a 33 S3 to a Motronic M2.10.3

    Carburetors, Fuel Injection & Air Intake
    Hello guys! Has anyone tried to convert the 1.7L 16V boxer in 33 to the newer version of Motronic fuel injection,put in 145 and 146?The benefits are significant-electronic ignition,sequential injection and hot wire MAF instead of vane MAF. Which sensors have to be changed for the new ECU?I guess...
