Installed the MAP ECU in my 87 Supra Turbo currently it has stock 440cc injectors with a T57 Turbo. I am using the 550cc map, but I took out 25% fuel out of the map and the car still running rich from what the wideband shows 10.5:1 at idle. I was told to keep pulling out fuel till it drops down to at least 14:1. But it won't go past 12:1 and that when I took out almost 60% of the fuel from the map.
Any suggestions or does anyone have a 440cc fuel map for the MK3 Supra?
Thanks...
