I just posted a topic asking about the same thing in the Corral this morning--I got one answer back so far saying that the A9P is the AOD version of the A9L and it has a slightly more agressive timing curve in it.

I just ordered a chip for my car today, my 89 has a aod and A9P computer. I asked him didn't all aods have the A9P and he said yes. I've heard of people putting the aod computer in a 5 speed, its supposedly more aggressive(it probably is).

I have an A9S Computer. I think as long as you dont have a 94/95 or cobra computer its not gonna make much difference.

I dont know the difference between the A9L and the A9P, but I do know that the A9L is the preffered one to have. Also from what Ive been told, you dont ever want to put an AOD computer in a T5 car as the fuel and timing curves are LESS aggresive. Call any tuner shop with Autologic software and they will know the answer.

The A9P was used with AOD cars, the A9L was used with manual trans cars. There's not a big enough difference in the stock computer programs to worry about which one is "better".
