Hello,
I know it has been discussed many times and I went through many threads about that, but once I did swap LS7 injectors for LS9,
I went into troubles. Because I swapped more potentialy troublesome items on my car at the same time, I just want to rule out
some of these. So here is my situation:
I had:
LS7, LS7 injectors, stock intake, stock rails, stock throttle body
Now I have:
LS7, LS9 injectors, LSXR intake, FAST rails, 102NW throttle body.
Poblem is that when I stitched together maps for my setup with LS9 injectors, my STFT went over 25% so I suspected my data.
I went back to previous software setup for LS7 injectors and still, my STFT is around +9-10%. I wouldn't believe, it's possible
to run lean with LS9 injectors on LS7 data, so I suppose I have vaccum leak somewhere (I tried it just on idle, not WOT),
but I just want to rule out the most obvious problems. I don't expect that LSXR intake, nor the 102NW TB would cause such high
deviation to MAF calibration as I did a few these in past and never had a problem.
Is there anybody, who can check my data for LS9 injectors that they aren't completelly off, please?
best regards, Filip
