Does anyone have any input thay can share tune2.hpt i have tried to adjust my injectors but i dont think im doing it right. they are from a 6.0 part number for injectors is # 12580681
Im struggling with these injectors. i cant seem to get the flow rate done correctley . Can anyone help me because im lost
Is your fuel pressure regulator vacuum referenced?
can you explain that ?
my injectors are ls4 injectorspart # 12580681 30 lb/hr @58psi
The tune i have is saying 24.2 lb/hr some how i need to get the flow rate on my tune to be 30 and then then interpolate from 0 kpa to 80 kpa i need to interpolate this an thats where im confused on what to put
Here it is.
I got it from a 2008 LY5 tune (avalance, silverado 1500, etc). The column labels use different units, but it's easy to get it moved over.

today i actually drove it down my street an heres my log file . still cant figure out why im not getting my o2 sensors to read an it was like dying out when i tried to throttle the car so i basically coasted an was able to give just a little gas . Also my ltft an stft arent reading either drive on street 2nd trip.hpl
The fuel trims can't work until you fix the oxygen sensor problem.
Problems on swaps is usually wiring issue. Very common for purchase harnesses to have issues.
O2s look disconnected.

Post the log.
If it was me though, I would get the wiring diagram for my donor ECM and check every connection, both for where it lands and for proper connection.
