ecu reset after upgrades Options

[carpcrew]

hi all, ive a 94 import with the 3sge engine, ive just fitted a apexi induction kit and a apexi exhaust and car idles lumpy, ive read that i can reset ecu to combat this idle issue by taking out hazard fues , ecu fuse and efi fuse, wait a minute then put them back in and let car idle for 10 minutes then switch off the on again and car should idle better, but min doesnt, it sounds the same, i found hazard and efi fuse ok but theres two ecu fueses, one in engine bay and another in the car by drivers lower dash, do i pull both these out or have i missed something, cheers rob

Then try this, worked for me.

Make sure that the engine is at full running temp, let the rad fan kick in at least once. Then remove the ECU fuse and leave it out for about 2 min. Refit the fuse, start the engine and let to idle for a bit and then go for a Quick drive using all the revs in the first three gears.
This should help your ECU to reset to new fuel and ignition pionts that are within its limit.

hi thanks , i will try it, also has i was tying to find fault yesterday i disconnected the maf sensor whilst car was running but there was no change in engine note at all ! i dont know if this is normal but ive owned a few jap scoobies and when they had hesitation and bad tickover it mostly always turns out to be maf sensor, if sensor was disconnected car would stall or idle badly, as i say i dont know if toyotas are the same, failing that it would be 02 sensor but i dont know were they are on a celica, anyway will try reset and post back, cheers rob
