Well i sont know what you mean about the 3 wire o2...that doesnt have anything to do with it. What I mean is that since the TPS at the ecu shows a constant of 4-6 (anything over 4 will read 100% to the afc) its not fully functional with our cars.
The reason being, is that since the afc has a high and a low setting feature you are normally allowed to control each according to TPS and TPS only. If the afc is always seeing 100% then the only thing we can tune for is high throttle. if you tune anything low throttle it will be disregarded sicne its always 100% and the low throttle maximum NE point is like 49% (signal from the tps) then its impossible.
However I was thinking that since we can screw around with the AFM's, that we could just adjust the afm leaner so it idles and does ok at low throttle, but during high throttle we can adjust the afc and it wil work, because we are always seeing 100% which is ok since the high throttle NE point minimum is like 50 or 60% or something and if it sees 100% it will adjust accordingly. I figure this is ok since Mark said that his idle and everything is ok with just the AFM adjusted as well as a few other MKII guys that dont even have an afc. So the advantage that we will have is we can lean it out a bunch with the AFM and then just ue th eafc to either richen or lean out a few spots where ever as long as its full throttle. So Im not all that upset anymore knowing that I will still be able to control at leist the important (full throttle) side of the tuning....
Im getting real close to finishing up my car. I will probably be done as soon as I get the rest of teh stuff from good ol' Aaron Garney. :evil:
