Hi guys,

i need help, does Megasquirt have a ecu that will work on a BMW E46 M3 343hp from 2002?

Thank you for you time.

An MS3 can run the fuel, ignition, and double-VANOS systems on this motor no problem. You'd want to keep the stock ECU running the drive by wire throttle and CAN messages if it's staying in the E46 (if it's a swap, you could just go with a cable operated throttle body).

@matt cramer, any tutorials/writeups how this should be done the right way? Keeping the stock ECU for the DBW & CAN control and have the MS3 run evrything else?
Cause i'm trying to achieve the same thing!

Thx!
