crappy idle: 80lbs inj on stock LS1

[FPSeth]

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?

Nevermind- I done figured it- something called an A.I.R. Pump that was coming on @ 12g/sec, which, of course when it was a wimpy NA LS1 that was a lot of rpm's but with a D1 blowing down its throat thats a hair over idle. These old cars are so funny with their EGR's and A.I.R.'s and god knows what other emissions crap.

So AIR pump was it...? Cool, glad you found it (I'm running behind in looking at people's files)...
