I recall throwing a 91 FWD turbo California ECU in my 90 AWD turbo Federal car. I got a check engine light (missing a piece of CA emission hardware) and the tach read incorrectly. Does any one remember the procedure for correcting the tach reading? Will this reading mess up my SAFC as well? Basically I am looking for an EPROM ECU. Being able to use 90-94 ECUs would widen my search options.
