a9s or a9p?

[Camman]

I have both computers now. This would be for my 89 vert, it is a manual. The a9p feels like it has more power, but this could be psychological . Thanks!

One of those is for an automatic. I think it's the A9P.

a9p was from auto cars, which supposedly adds more timing to compenstae for the auto. But either will work. Just go with your gut, you say the a9p works fine, so leave it. If it aint broke, dont fix it

have u guys ever heard of an A9T I have one but don't know what it's from it worked on a 5.0 ho no probs.

 

[TIMMY2734]

there are soo many computers that were used for mass air cars. A9 is or should be the same family though

 

[Fostang]

Well what family would it belong to under the tweecer groups???

 

[GT40XStang9]

A9T's came in '89 (only year I know of - could be more) model years with AODs.

 

[GT40XStang9]

Turns out - '89 is the first and only year for the A9T.
