i have a 2013 zl1 25k on it
18% percent overdrive pulley rotofab intake lt headers no cats id 1050x injectors and all the correct data
ive tried the 3 different ways to enter injector data
1/2 ivt double stoich 1/2 ifr
used multiplier
and also set constant 400 kpa in fscm ive even taken the maxed data in fscm and used 1.866 multiplier. match both fscm and engine ifr tables also
I always have to add over 20 percent fuel at 2500 rpm and extra pe still yet to get correct afr.
if i go any higher with ve table its messes up above and below that rpm rang if i use the maf i end up with two frequencies with same lbhr. i have to use all three. PE VVE MAF just to 12 afr.
All limiting has been turned off so im wondering the Can this be part of the intake valve temperature chart throwing it off??? Why 2500 rpm??? Ive moved rpm boundaries map boundaries tuned 2bar table vve. once i hit 2800 rpm to redline its fine. can someone give me a hand as to why the vve isnt being calculated correctly. what parameters do I need to change in order to get rid of this problem.
is there a a predicted coefecient i need to change. also ltft and stft at lower rpm says pull fuel also yet if i do it goes way lean. I dont want to use open loop airflow gain multiplier to compensate as I don't feel this is the "CORRECT WAY" of tuning. I could do it and multiply 2400 and 2600 vs kpa but this still wouldnt explain why???? its off by 20 percent for crying out loud. ive just managed to compensate using all three tables
