2002 camaro auto LS1 w/ Procharger D1, all stock sensors, trickflow/Bosch EV1 80lbs inj
Before you all harass me for putting 80lbs inj where they don't need to be and for not having correct injector data before tuning- I know, but I'm trying to work with what I have here in front of me.
Only issue is at idle, on start up it it will idle really lean until I just 'blip the throttle' then it falls into a rich afr- but look at my VE table- it makes no sense that I have 100%VE @ 55-60kpa in the idle areas then a sudden drop off into the 30's @ 'normal' vacuum areas. Rest of the tune up is great with minimal corrections.
I attached a log of me putting it between N and D and you can see how bad the AFR jumps at idle, yet the IBWpw is not that different. Could this just be a matter of bad small pulse injector data and latency data or is there something on these GenIII's that I'm missing or that I screwed up?
