A9L is a mass air computer that can only be used on manual transmission car. A9P is a mass air computer that can be used on auto or manual. Both are great computers that respond pretty well to modifications.

i heard the same thing about the A9L. I have a 94 and the computers in those are not supposed to be as good as the A9L. Would i be able to put the A9L in my car just plugging it in? or would i need to change things?thanks
