Doing an M30 swap?

Using the M20 engine loom...


ECU
The standard E32 / E34 ECU should be used. The M30 loom will allow it to be fitted under the dash, but getting all of the connectors through the bulkhead is a PITA! The loom is also slightly short - you may have to rotate the ECU to allow it to bolt in place.

You say the e34 ecu 'should' be used. So a 173 cannot be used?

If you put an M30 chip in it, you can use it.

m30 and m90

[biodose]

So any m30 chip? Because this is what I have...

[Hooffenstein HD]

Not sure what that ECU is, sorry. If it's M1.3 it should work. I was using a 173 chip in a 179(M30B35 M1.3 ECU) in my M20 car for a bit.

EDIT: Looks like it is M1.0 Basic. Not M1.3.

[biodose]

Reason I'm not using that 059 is because the connector does not plug into the 1990 m20 harness I'm using. The 059 is what came with the B35 I pulled when I lived in England.

[biodose]

Well thanks for your help! Guess I need to find a chip or a 179!

A 179 ECU should be easy to pick up.

I've got 3 or 4 of them in my parts stash :D (I'd send you one, but shipping from Australia would likely be too much to be worth it).
