Just putting this to the top. Need Bill or someone to help me out.

So I took my car to get it professionally tuned and the guy put someone elses tune in my PCM. He also changed the VIN number in my PCM. I told him to make it to where I can get into my PCM so he...

This turd is running WAY TOO RICH! Too rich to even drive it. Here are the specs.

*02 LQ4 Flat top Forged Pistons 10-1, fresh build
*Comp Custom Grind Cam...

I have a 74 Corvette I'm doing an LSx swap on with a 4L60e. I am trying to get the tach to read correctly, and from my research, I've came up with this. Everyone knows the LS1 outputs a 4 cylinder...

I have been having a problem with my engine idling and I have found a way to temporarily fix it but I am curious if it would be a permanent solution without harming my engine. Basically if it tries...

Guys I am having issues and I dont know why. I set the the tune up with the way the online guides say to. It kinda runs, not real well, but kinda. Then I go and try to tune the VE table with VE-AFR...

Ok just got back from the store no backfiring but it did try to bog out on me. Not holding idle by itself anymore tho. I wish I could see the histogram for AFR Error % but all the information I...

Ok guys I have restarted the entire process, only this time I didn't use any other tunes to plug into my tune. I used my tune that was completely unmodified and did exactly what the help files said....

woops uploaded the wrong file. I put the wrong tune on I believe. doing it again.

**Added the stock tune with 2 bar support, nothing else done. Welp it wont even run now so I am going to attempt...

Ok I just applied my stock tune, converted it back to 2 bar and did a write entire. Log file is about 10 - 15 seconds of running, no backfiring. Am I ok now?

I hope HP tuners will help me out on this, I really dont want to spend another $200 on credits...hell I cant afford it.

Ohhh I see what your saying. So basically you are saying I have to start all over again, buy another 4 credits because my software in my PCM is and it cannot be fixed?

Ok I found a completely different stock 2000 Trans Am w/ Manual transmission out of the repository. Is there a way to to write that tune to my car or do I have to change my file to what this one says?

Ok I will see if I can find my stock file.

Another thing I noticed when I do my past multiply by % -half it still adds to the number that I paste to in my Primary vs RPM vs MAP. Shouldnt it subtract it?.

Ok I let it run at idle longer this time, I had to keep the TPS sensor to 5% this time to keep it from dying. Here is the log file. Still backfiring yes...

Also reading through one of the help files I read that IAC sensor should read around the 60s range. I reset mine, set the TPS sensor to 2% like the guide said, turned key off, unplugged, plugged in,...

Also I wanted to provide my fuel injector data. I am running stock LS3 injectors. I did a check on the the PSI and put it into that excel worksheet. Their rated flow rate is 41. LS3 operates at 58psi...

This is what my table looks like so far. I have been trying to correct things in here, and the more I correct, the less it will just idle. So far I am having to keep it idling via the gas pedal...it...

On top of all this let me show you what I have been trying to do. I think its what I am supposed to do from reading various help files....

I really dont have the time to wait for Monday for them to respond. Is there anything I can do to alleviate the problem? Is there a beta version I can download or is this a problem in my HP tuners...

Yes it is backfiring BAD. I would assume it is from the many tune attempts I have tried to make and failed. I downloaded the most recent version of HP tuners that did not use microsoft frameware...

I have yet to get this figured out folks. I have a 2000 Trans Am, 408 stroker, P1SC Procharger, Mild cam, 41lb LS3 Corvette injectors.

Problem.
I can get it to idle but at idle it reads nearly...
