I'm going to socket an ecu for my csx-t with a 2.5 t-1 in it. Right now I'm running an 89 t-1 smec, but my 88 t-1 smec is just sitting in the garage. I know the 89 has more code in it than the 88, but didn't know if this would make a diference since it's going to be a custom cal anyways? Can some one clue me in on wether or not it makes a difference on which smec I use? Thanks alot. Also if anyone has a good place to get flash memory 28 pin dip chips, that would be helpfull too.
