I have been thinking about switching to mass air and I would like to get the 5 speed computer from what I read it is a little better. is the A9L from a 5 speed or is the A9P from a 5 speed
quick ? about mass air

A9L is definitely from a five speed. Not sure about the A9P, but I know someone else will be along shortly to confirm that. Been too long that I've been without a Fox, so I've forgotten quite a bit.

a9l can only be used in 5 speed cars. the a9p came in automatics but can be used in either 5 speed or auto. they're both as good as the other and respond well to mods. i actually like the a9p better in a five speed. i put an a9p in my 5 speed coupe and it ran like a CHAMP. also, i just did a mass air conversion to my current car while i'm rebuilding the motor on the stand and i'm using another a9p.
Both are correct above. EDIT: Cenok posted while I ate. Good info from him also 
The P tosses in some extra timing (to accomodate the converter/box) and the 5 speed guys seem to like it ok.
Jason (Vristang) has recently made an interesting comment about the low RPM timing advance with the P (it's a lot under certain off-idle conditions - again, because of expected converter stall. But for a 5 spd, the driver would not realistically notice the difference).
Go with whichever puter you can find Roland.
Good luck.
