need Some help with LT1 MAF issue

[Fastmax32168]

Thanks for the responses. This problem isn't exactly what I thought it was, it was adding fuel everywhere before I replaced the MAF and I thought that problem was back but it appears to be mainly at idle now, and worse on the right bank. I sure would like some of you that are smarter than I am to have a look at this file though since it is all over the place. This is actually my first EE hack file here, I have always used tunercat, but there certainly seems to be a lot more info in this program. A little history here, I have had this car for 15 years, it has a very healthy 383 in it that will propel it to high 11s at our local track. I left it sit with little use for a few years and it was running badly, so I cleaned all the njectors installed a new fuel pump and filter, opti, coil, plugs, wires, and maf sensor to freshen it up. I have new O2s here but haven't put them in yet. Other than the poor idle, it sounds and runs decent driving it around, but as you can see from the file, the tune seems all over the place. I looked hard for air leaks either before combustion and afterwards and really cant find any. Keeping in mind that this same tune would log good a few years ago, on the exact some motor, is it possible that changing around all of these components has affected it to the point where I need to start over again, or has something else gone haywire? Any input here is appreciated. Thanks
Update: I cant get the eedata file to upload and attach. It keeps saying invalid file. I dunno

You can zip the logs and than try to upload.

Thanks, let me know if you can open it now

You are having some troubles at idle, blms jump to 160.

To isolate some of the causes can you command open loop throught the control section of eehack on warm engine.
Just click on the overide AFR checkbox, top left.

If the lean condition is real the 02s will read low and the engine will run like crap and try to die.
If the lean is false the 02 will again read low, but the engine will run great without issues.

This will help us isolate some of the possible reason, leak in intake or leak in exhaust, misfires and so on.

Very interesting idea and great feature on the EEhack program. I attached a file of my doing as you requested. After a few minutes of running when I figured it out you will be able to see when I disabled AFR and reset the BLM. It did not die, it didnt idle perfect, but it wasnt really worse than when I had the O2s at work. The O2 readings dropped out the bottom, are they actually still functioning or are they just disabled by EEhack? After a few minutes I reenabled them and it began to immediately march its way to 160. I am wondering if it might not have a leak in the valley under the intake, I have just discovered I have negative pressure at the oil cap when doing the strip of paper test. Thanks for the guidance.

you said you've searched for vacuum leaks, have you plugged off every vacuum line including the PCV and see if things change?

that log looks like when i had a big hole in my brake booster.

do you have a log of when your engine was idling healthy? i'd be curious what the intake vacuum looked like vs now.

The O2 readings dropped out the bottom, are they actually still functioning or are they just disabled by EEhack?

still functioning

Definitely air leak after the maf or Air pump leak leading to fresh air in the exhaust. You can also check ccp solenoid for stuck open with leak on the lines sucking fresh air.

The final test will be to command open loop with maf disconnected.
