No. I've looked into it from the opposite direction for those interested in ditching the piece of **** 94/95 PCM in favor of the much more desirable 93 PCM. It'* not worth the trouble. And the trouble is amazing in it'* complexity.

Why on earth? Stick with the 93 PCM, and tell us your problems so we can help you solve them while keeping the 93 PCM.

For the record, I own BOTH.

Soooo many fiero guys use the 94/95 pcm. And it'* not like a large percentage of people on here have problems with it. I can't see it being such garbage as it is always refered to on here.

Mike, to get a PROPER PCM like they do, you have to have dyno and scan data to specify what you want. Most of the details needed to get one are beyond the reach of the average bonneville owner.

The 93 pcm offers the best of the best. A stable L67 PCM with the 'flash' feature for ease of troubleshooting, a standard scantool setup, a non-hybrid PCM, and a good aftermarket PCM ready to go off the shelf.

I have more issues with my 95'* PCM than I have ever had with my 91... The 91'* all be it slower and not as complicated as the 95'* has been better by far... I am now on about 3 years on the Reman AC Declo ECM on the 91.... My factory puter took a puke, then the Reman took a puke, the junkyard unit took a puke.... And now I am on a PCM that came out of a low mileage 95 Bonnie... Its been well over a year so far with no more issues...

In my eyes the 94-95 PCM is junk, and a lot of people have a hard time determining when it actually goes bad... I won't be swapping as the PITA factor... But its a good thing the Auto Parts store can get another one in a pinch

Did I mention that when I go on vacation I always have a spare PCM in the trunk

I had some small issues with my 95 and was scouting yards for a 95 PCM...

One thing I learned... so many of them puke that there are never any to be found.

I'm OBD2 and have no opinons on which is better...I see them as old and older...
