marcello7x Posted March 4, 2015 Report Share Posted March 4, 2015 (edited) I started a thread on HPtuners when i first started tuning the truck a few days ago and had issues starting it up in subfreezing weather. Turns out it was super rich and i was flooding it.After letting it cool a 3+ hours last night it was below freezing out but ECT was still around 40*. Anyways she started right up, as well as this morning. Tomorrow will be back down to below freezing in the morning and i will log another warm up.In the meanwhile here is my current tune and a Log from this mornings warm up as well as the drive to work[edit drive to work log is too big to attach]. I made a few WOT since i saw my LTFT were dialed into +/-3%. I did get some KR, so i need to go back and dial back timing in those areas for now.The two logs have a LC2 wideband reading that makes no sense. The sensor seemed to crap out so Im going to run new ground and power wire tonight.My Idle is still to rough and needs work, but at-least shes derivable for now.
