Does anyone know what the "best" computer to use in a speed density to mass air swap is? I have been told that A9l and A9P are both good. I have also been told that the A9P was originally in automatics and has less timing than 5 spd versions. Confusing!

I've been told that it is better to use the A9P(auto) when converting to 5Spd MAF because of issues dealing with rev. limiters or some crap like that.

Either would work well...
The timing differences are not all that significant.

I'm interested in this as well as I will be doing the swap this winter. Where are you guys finding computers? Ebay? Junkyards?

I have found computers from both of those sources.

There is a small amount of risk, as you can't test a computer on ebay, or in a j/y for that matter.

Check with parts stores too, as sometimes the refubished units are quite resonably priced.

I paid $75 for an LA3 computer on ebay, but could have purchased a reman'd unit for ~ $100.
If it is in the budget, a new/reman'd computer is less risky.



I asked how the reman'd computers were of lower quality...
I doubt there is any difference at all.
The computer code won't be any different, nor will the hardware of the EEC.

I asked more as a challenge, as I don't see any way one EEC-IV can be inferior to another, with the same catch code.
