Why are the fuel trim values different for 1990?
120%~80% for 90, 140%~60% up

Different ecu and wiring would probly have something to do but other that that, I have no idea.

It must be somthing with the ecu. thanks

Jackie Chan said "lets fuck with their heads and change the fuel trims".

It's called "after a year of production, we made some changes to things that needed improvement". Most first year production runs have more problems than subsequent models.

Thanks for calling my car a pice of shit! No just kidding, but I was thinking the only thing good about a 90 is... the oil cooler, and I like the flip up head lights, mainly because of laser guns, just one less spot for the popo the get me. :rally:

Nothing wrong with them, Mitsu just decided to change for some reason. A DSM is a DSM.

Ya I know, I see things change in the model year, somtimes four times a year on KIAs
