im having problems with the 02 map... may afr doesnt change when im decreasing the 02 map. i dont know where i went wrong but i watched the video of the 02 narrowband ,,..
this is what i did..
1 i tap the 021+ to AFS+ of the honda fit ecu without any resistors
2 put a wideband PLX mte 300
when i adjust the 02 map the plx still see,s 14.7
aslo tried in offset mode and percent mode..
connected Maf, MAP (to analog A), tps, CRK, CMP, POWERS and Grounds 021+
what is 022+ for..
Can anyone guide me.. I can send u may calibration file to check or aemlogs. thanx
1. 09 FIT GE has wideband sensor other than narrowband one.
2. Set you O2 mode to Voltage and have High Level Drive checked.
3. Tune you O2 voltage with starting at 2.16V and you will see AFR locks around 14.8. Then tune upward and down.
