Hey guys im having a problem here and trying to figure it out.
My truck runs great AFR in the low 11 all the way up through the gear but at the top of a pull the commanded AFR will step up a little and then at the very end of the pull will fall out the way out of PE back to commanding a 13.98 AFR. Ill attach the logs so you guys can see what i mean.
What does your P.E. Table look like?
from 2700rpm on its flat at 1.270
Post tune file
there it is. hopefully we can figure it out.Originally Posted by Eperformance
no one has any idea whats going on?
that is quite bizarre looking at your log and file.
pretty out of left field but does it do it if your tune in SD 2bar?
converting my computer over isn't an option. I got it to stop making the big jump at the end by matching my PE for gas and alcohol but it still jumps between 11.2 and 11.8. Next step if i can't get it figured out would be to tune speed density with the VVE table.
Since im street tuning that should be fun.
for anyone that is following this or if anyone comes across it. Once i made all the alcohol and fuel tables in the fueling section and PE section the same the problem went away.
