Hello, does anyone have a afr wideband gauge in his st205 with oem ecu?
Im interested in the afr under boost under 4000rpm (2500-4000 with boost) and over 4000rpm.. in 3rd or 4th gear.
My issue is that i have a afe from 13.1/13.5afr under 4000Rpm with full boost and after 4000rpm a 11.1afe and i dont know if that is normal or what the problem can be if not normal.. map sensor is it not because i changed it already..
