ok so i have tried to find a solution for my problem that has just popped up out of no where. i have looked around for a solution in these forums and cant find a similar problem mine or i cant search for the exact problem im having.
i've had this tablet and header since May. i've ran the E85 tunes since then with no problems and the changed my oil every 3,500 miles. But at the end of September i switched it over to 91oct tune since it was going to get cold and i didnt want to mess with cold starts or adding 91oct into the mix of E85. Drove around for the first tank of 91 easy. it was reading a little rich which i thought it was fine due to 91 tune. but then on the second tank it started getting FLKC all the time no matter what throttle input i gave it. drove easy still and waited for the 3rd tank thinking i got bad gas on the second one. 3rd tank comes around and it gets worse. FLKC are anywhere from -.69 to -3!
so then i decide to go back to E85 thinking it was a bad tune i must have flashed and wanted to get back to a safe tune. flashed E85 tune... drove fine in the first tank mixed with a little of 91 still left in there. the moment i go to the second tank of E85 my LTFT go up like crazy! on start on and warm up they go as high as 25% and during cruise they climbing up to 15% and under acceleration they only settle around 3% to 8% and hardly getting to 0%. some times under hard acceleration without going WOT it will occasionally hit 0%.
ok, so thinking again maybe bad E85 i decide to go to another station and fill up with E85 on 3rd tank. the warm up seem to settle close to 0% but the LTFT sit and dont move at all at 17% on idle.... i drive around for about 100miles letting it learn the "new tank" and i only manage to get the LTFT down to 10% on WOT which is reading 11.25 AFR and the commanded AFR is at 12.59 for those of you that know E85 are supposed to be there. on my 4th tank i start thinking that maybe something is clogging the intake so there for its not getting enough air and its injecting way too much fuel, i unplug the intel that goes to the airbox where the airfilter is. thinking that maybe there was something clogging it and to see if that would allow a little more air in. which it does for about 50miles the STFT drop down to -7% to -12% and its starts running lean again up to 15 AFR on cruise and the LTFT start to drop down to 7% on WOT. happy thinking that maybe there was something stuck on the inlet i decide to run it like this until the LTFT drop down to 0%. but... after this they climb right backup !!! on warm on they now hit up to 27% STFT and LTFT are at 22%! under cruise and acceleration they go back up to around 7%-15% STFT but the AFR are around normal 14.5 - 15.20 and my LTFT on WOT are at 14% running 11.25 AFR!! IM so frustrated and cant figure out why its doing this!
i have flashed 4 different E85 tunes now and this is my 5th tank and still doing the same thing! any help or suggestions! please!
here is a log i did when this started happening
