Ecm ?

[hotfordcat]

I just put a B6 in my white festy, and I tried to use the 1986 323 ECM. My festy had a two plug ECM and the 323 was a three plug. I used the Festiva one and the car runs. So, I checked my stash and found a B6 two plug ECM. My question is, do I leave the Festy ECM in, or swap in the B6 two plug one.
Thanks in advance for your input.

swap it out for the b6 one.

Thanks Wes. I thought for sure the early B6 ECM was a plug and play.

only if you have an 89 auto...

REALLY? The ECM came out of an 86 323 with a 4/speed. Learn something new everyday.

Well i should i re-phrase that. If you complete a manual swap from an 89 efi auto. You can use the 86-89 3 plug ecm.
