i have an 89 notchback that i converted to 5.0. the eec harness came out of a 93, im using a c3w computer with an eec-tuner. the car run good.

i have always read that the a9l was the best computer for cars with mods. i have looked at both the a9l bin file and the c3w and there are some different tags in the a9l. would there be any gain going from a c3w to an a9l. i know the a9l is for a manual car, what has to be done to make it work in an auto application.
