Hi All,
i am new to tuning for my Gen4 Ly6 Engine with 6l90 Trans. i am running MAFless setup with only running Front o2 sensors and standalone IAT.
I am asking for support to check my logs and tune file and give me some tips and hint and what shall i do for better performance.
also i am looking forward for better pedal response After Writing New Change 26Jan.hplHawas new Changes26Jan.hpt
Check that IAT wiring or something. The log starts at -40 degrees and then it comes alive and stays at 68 degrees without moving at all.
What is your fuel pressure on a manual gauge?
The o2 sensors show that it's really lean at idle. Or you have open headers still, which will throw everything off.
You will require a wideband o2 sensor for tuning this. VVE tuning really needs a wideband to dial in the fueling.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
