Ok I just checked my computer and I was going to see if it has a chip or not. well it doesnt. But Iwhile I was looking I noticed that the computer was a a9s computer...would a 89' Lx with a manual come with this computer...I rember my other 89' lx with manual came with a A9L computer.would it make my car run better if I put a A9l computer to help fix the idle issues with the cam?

a9l is the most common computer for 5 speed mass air cars.

would I benefit by switching to the A9L computer?
