1998 c5 brick issue after 3bar swap?

[JASON11WS6]

Anyone else have an issue have they converted to a 3bar set up? I performed the modification to go to a 3bar. Saved it, uploaded it and the car wouldn't start. I noticed I was getting no afr and no spark on the scanner. I switched back to the last maf tune the car had we have the same issue. Car ran fine before this tune. I even did a complete reflash to see if that would help and nothing

Where is the 3 bar tune file you flashed to the vehicle?

That's not a 3 bar tune

It doesn't even have a 3 bar option. Only 2 bar.

Anyway, the reason I said post the 3 bar is because of this ^^^ If you aren't populating the VE this is what it looks like. It won't run like this. Also, if you don't fail the MAF correctly, won't run.

Without you posting the actual tune you're trying to run it on it's all a guess. And being evasive in your posting doesn't do you any good.

Sorry yes, 2 bar is what Hp converts the early ls1 stuff too. Here is the last tune I tried. When I first tried starting it I had a bad map sensor that would not read. I replaced it, got a reading but noticed nothing else was reading in the scanner. The afr doens't read anything and it has no timing. I went back to the last maf tune I had and it's doing the same thing. Is it possible the ecu bricked? It still reads ok

Every bricked 97-98 style PCM I've seen you couldn't read or write to it after it bricked. You will usually also lose the fuel pump prime with key on when bricked too.

Show us the log with this https://forum.hptuners.com/attachmen...1752075604.HPT file of you trying to start it.

Here is the scan on the attempted start up. Not much is reading.

[edcmat-l1]

You're logging way too many pids for the PCM. I'd get rid of all of them except RPM, MAP, MAF, timing and injector pulse. It's not reading any RPM but because you're logging so many pids it's difficult to tell if that's a problem with the car or with the data logger.

See if you can write entire the original OS and .HPT file. I don't think that is a PID overload issue.
