I would check e-bay if you dont have any luck on here. Thats where I got mine for cheap and brand new.
The ECU does that to compensate for changing conditions on the car such as a fuel pump slowly going out etc.whys that?
Open loop operations are effected by the long term fuel trims that were adjusted in closed loop operations. So the thought process that at WOT when the ECU doesn't listen to what changes the ECU has made left us back in the 90s.Not to change this to a safc2 info page but would the changes work if the ecu is in "open loop" due to a bad o2 or something. I read that somewhere on another mitsu forum a while back. Just wondering...
