overall fuel trim

[boostedeh2]

I looked at all the calibrations that was posted and noticed that none of them uses overall fuel trim? On mine I put in the fuel pressure of 45 and it gives me the value of 85% for overall fuel trim. Am I missing something? I'm running running pte 880cc with 1000cc battery offset..I messed around with the offset,ect,iat and got the idle to be around 14.5-15s afr but the rest of the map seems to be extremely rich, especially from column 4-up...seems to be in the 10s afr. What could the problem be? or I just need to edit the rest of the map till it gets to the desired afr? Any help would be appreciated. Thanks

Yes you will need to tune the maps. It sounds like you are pretty much running off the basemap eCtune created. It will still need to be tuned for max power...

I messed around with the overall fuel trim and the injector offset some more. Before I was using 85% overall fuel trim along with about 30FV injector offset value, I got the idle afr to about 14-15s, but the rest of the map would be extremely rich, around 10afr...even on some part of the map when I lowered the fv all the way down it was still rich.... well after looking at all the .cal posted on here, no one was using overall fuel trim...so I decided to set the overall fuel trim at 20% but I had to bring up the injector offset value to 95FV...the map is much better now and isn't as rich anymore.
