Default Getting MAF ECM, any sugg.?

Well im doing all my homework on upgrading to MAF, now im stuck on what computer i should get, i hear that the a9l's are the best..... why are they? also what is the diff from the a9l, a9p, and a9s, i know the a9s are the CA computers but does that mean i have to have all my emmisions for it to run right?

i dont have smog, egr, a/c any of that stuff, also i have a 5speed.

i think im going to get the a9s because of the cheap price, should i be talked out of it?
let me know

also planning on getting the chip dyno tuned, can they change whatever problems i might have with the a9s?

Typically when you make a post, you should include the year, model and trim level of your car, along with any significant mods

I would use the A9L over the A9S or A9P.

The A9P was meant for an auto, so there are some timing and fuel differences related to shifting (when comparing the A9L to the A9P).

While the A9S will probably work well, I don't see any need to use it.

You can compare the A9L to the A9S to the X3Z on my site...
(it is a large page so it may take some time to load)

Seattle area enthusiasts should contact me via pm!
