Stumped ls2 04 GTO

[tana99ss]

So im reviewing my buddies car because he’s having drivability issues

I connected my 4110 Aem to it and I get a .92-1.00 start up then it goes super lean at idle

I haven’t tried logging it while driving cause its 1.26+ lambda and I dare not take the chance. I thought it was my sensor so I replaced it with another working one I had , same thing, bought a new one same thing.

I will post logs here in a few but has anyone ever had these issues?

Car is OL tune right now

I got it figured out , previous tuner had all types of data in it , changed it all back to stock and started fresh …….. time to get it rolling

Good ol OL tune strikes again. Anytime you see OL assume a chimp tuned it. You did the right thing starting over.
