ok. first post. first time using hptuners.
i've been researching and using the forums and tune samples as much as i can regarding my setup.
5.3 LM4 - gen 3 aluminum 5.3 engine - stock
BTR stage 3 truck cam (specs pictured below) - upgraded springs/lifters, stock pushrod length
gm 50 lb/hr flex fuel injectors 12613412
255 lph pump
58-60 psi fuel pressure returnless system
706 heads
truck intake
drive by wire - 02 Silverado tac and tb.
stock maf/sensors
0411 pcm
4l80e trans
trying to get the truck to start and idle. played with the tune using suggestions/files/other tunes and tables others have posted.
truck now starts and idles, but the warmer it gets the richer it gets.
will begin having misfires on all cylinders after about 2-3 minutes of run time. will eventually foul out plugs unless i clear it out above 2500 rpm.
smells super rich. innovate motorsport lambda gauge is showing a fluctuating lambda around 1.04.
i am attaching a few pictures, as well as the current tune file and a log file of this morning's start up.
i'm just looking for help to get it where it can run well enough to let it just run, and perhaps move it to the other side of my garage under it's own power.
thanks anyone that helps.
