Have you tried to incorporate lean cruise into the .bin? Sounds like it's leaning out under mid MAP. I don't think it's pick up coil or you would be having misfires.

Hmmm, you got me thinking. Data log doesn’t show lean cells but the AEM wideband o2 gauge does. Could it be the 3 wire o2 sensor?Have you tried to incorporate lean cruise into the .bin? Sounds like it's leaning out under mid MAP. I don't think it's pick up coil or you would be having misfires.
Could be if you have leaned out the .bin. Normally the if the O2 goes bad it will go into open loop and run off the programmed AFR table. Look for O2 cross counts in your datalog.Hmmm, you got me thinking. Data log doesn’t show lean cells but the AEM wideband o2 gauge does. Could it be the 3 wire o2 sensor?
That's not a part I would used in the used condition. They're only good for about 60,000 miles.I go to the salvage yard a lot and when I see an ac delco sensor that looks good I buy it. I have 2/ o2 sensors
Do you still have the stock unmodified .bin? For $hits & giggles drop that back in and see how it acts. Do a datalog and focus on TPS,MAP and O2. Look for any glitches in readings. Maybe even take the emulator out.
Good idea. I’ll load the stock VE and timing table. Should I set fuel pressure to stock? Its at 23psi and 89 lb/hr in the bin. If so 12, 15 or 18psi?Do you still have the stock unmodified .bin?

And money on the Burn 2. Started burning, the emulator got unreliable for long term. I only use the emulator for open loop and real-time tuningThat's not a part I would used in the used condition. They're only good for about 60,000 miles.
Good O2's are $40-$70,I'm sure you've spent a hell of a lot more for your emulator.
Spreadsheet numbers! 83 lb/hrStock flow injectors? Go 14-15lbs. Why so much pressure? Why 89lbs/hr?
I don't think you're making enough HP to support that much fuel. Lots of headwork?
