I have 2 maps loaded one map adjusts Co reading and the other doesn’t. I am pressing the map button to change the map and tuneecu shows that I am in that map, then set idle correction and global correction, then re adjust idle correction. The wierd thing is I can get one map set as I want but the other seems unresponsive. I have O2 sensor turned off on both maps. Can anyone explain If you have O2 sensor does it adjust the fuelling in both directions ie reduce if rich, increase if lean? But luckily the map that adjusts is working fairly well.
