I am VERY new to working on ecu and tuning maps. I bought my car from someone who already had the ecu installed. He went and got it professionally tuned and they said his Idle Air control was bad. So the tuner made a map for the bad "IAC" and made another map for when the IAC was replaced. I bought a new IAC through Subaru for $370. that hurt. Installed it and the threw on the new map.
The "cat tune good iat" map was idling at about 3.5-4k
so i through the "cat tune bad iat" map back on and its running at 2k. better but the idle is set to run at 900...not 2k or 3.5k
i hope i can attach the two maps....
