I just bought version 2.24 of HPTuners for my car. It has a LS3 with the GMPP E67 computer. With the headers and intake, it is running lean making it dump extra fuel. My LTFT is in the double digits and I have cleared it out once after driving for a bit to make sure. The STFT seems to hover around zero, but it does bounce around.

I found a really nive write up how to tune your engine on HPTuners, but it dates back to 2008 and the guy hasn't been on the site in a while. He states you need to run the scanner with the LTFT turned off and use the STFT hst file.

Here is the problem. I have a message under the STFT and LTFT stating those histograms are not available. I tried going to HPTuners Help file to set them up, but I followed the instructions and still get nothing. I am confused. Obviously I am missing something, but I have no clue what I am missing.

Any help is appreciated. Asking a question like this on the HPTuners forum is probably like asking how to put gas in your car.

Are you 100% positive you're not looking at STIT/LTIT when you get that message?

It's because your OS has a virtual VE table and those histograms are set up for normal VE tables like the older OS used.

deff double check this kinda goes hand in hand

The preset histograms 3 and 4 do that on every gen 4 data log that has a virtual VE table. Here are some histograms you can use to calibrate the MAF vs STFTs depending on the type of MAF table your OS uses. Put the tune in MAF only mode.

I am going to the Histogram section in Scanner in columns 3 and 4. They are empty. I only have column 1 and 2 taken.

Thank you 2xLS1 for the zip file! I really appreciate the help!

Ok..so I went to load them and I still get the same message. It says they are not supported with the current parameters. I have the same version of software on my laptop, but there are no credits attached and there are empty charts showing in the 3rd and 4th (actually, 5th, 6th, and 7th column also) column. Why do they not show in the version on the other laptop that has the credits for the GMPP computer attached?
