Anyone have any experience running a standalone ecu on these
I know aem have a plug in play infinity series for the e46 m3 but not sure if it will work on the 330
I want to run a turbo on one of these
It will work
But can i add map for turbo to original ecu ?
The MS43 ECU used in your car has reasonable tunability. I would recommend checking out the MS4X Wiki and having a read as a starting point
