Given the dearth of decent 320's in my local scrappy's,

been wondering i fthe e34 ecu's for the m40 1.8, m20 2.0 and 2.5 are the same as the e30 counterparts?!

Don't suppose they'd be different?

Check numbers first tho?

same as dude, well for the M20, M40 engines anyways

as Dave has said, just get one from the correct engined model... or any of them and swop your chip into it, they're all the same on the inside.

Oddball ecus' are for the M42 engines, they run a 175 (e36) stylee ECU and are poop :wink:
