New Computer (pcm)

It's an A9l if it is 5 speed, A9P if it's auto. I would check craigslist first. Then eBay. Don't pay more than 100$. They are out there

Some people may knock of me for telling you, but, you can put a A9P back in there. I am running a A9P on a 5-speed. The only thing is when shifting, the RPMs go up about one RPM for a split second before dropping down again, not really a big deal in my opinion.

Well I am not going to knock you. I am using a C3W '93 auto PCM with my 5 speed and it works just fine.
I was told by a Ford Racing Electrical Engineer that you can use an auto trans PCM with a 5 speed car but you can't use a manual trans PCM in an automatic car.
He also told me that a little known fact is that the auto PCM has just a slightly hotter tune in it than the manual trans PCM to compensate for the power robbed by the automatic transmission compared to a manual.

A9L in my C4 powered car and no problems here. Tuning with an Anderson PMS in this instance however.
