if your car is SD you need an SD ecm

i just converted my 86 from a sd to mass air and had to put my stock computer in for some testing, it ran but not well, if you have a mass air car it will run with a sd computer but it won't be the way to go, if you want your car to run right, get the mass air computer it's the only way to go.

my little red 90

i believe an A9L is the one you want.
