hey guys, I recently inherited a computer from my friend. It says its from a B18 A. Along with this computer came another one, and i believe it is brand new, but looks SLIGHTLY*different from the other one. It might be like an aftermarket one or something like that. I have a B18B1 motor( 95 rs) and was wondering what the difference is on these two motors, and what will this B18A computer do for my motor? thanx a lot! oh, by the way u guys know what these computers sell for?
