I'm working on an engine swap into an older car, the engine and trans are LY6 6.0l with 4l80e from a 2010 express van. When the customer brought me the engine and trans it had the ecm with harness...

That's because it needs to be on 2.25 to do the 4l80e segment swap and 2.24 won't read the tune after that.

Thanks, real helpful.

Offset vs volts vs vac table? That table looks far more complex then any any injector data I've seen, or am I looking at the wrong table. I've changed the min pulse width, I decided to go 58 psi base...

I have the injector data, that's not was I was asking for.

I added some Ford credits to my account so I can tune a Ford but when I try to save the file it shows I only have GM credits, my account shows the Ford credits. Do I need another application key or...

Sorry, bone stock LQ4 with a small turbo with SD tune. I wasn't sure sure if the problem was related to the P0068 or not and turned it to no error just to see if that made any difference, and of...

I try to make a pull and the DBW throttle shuts off over 3500 rpm and Makes me reset it. If I cruise easy its fine, I don't know whats wrong. When this happens the scanner freezes up so I can't log...

Worth a try anyway, thanks.

I have a Hummer H3 with a bad BCM, is that something HP tuner will let me program or is that a dealer only thing?

Great thanks for the info!

YOU WILL HAVE ONE OR ALL OF P0101/P0102/P0103 SET WITH NO MIL LIGHT, THEY MUST REMAIN THIS WAY!!!!!!!!!!

Why should it be this way? Why not set it to no error in the DTC section?

I looked at the file again after changing it in 2.24 to SD, and opened it in 2.25 and now the VE table shows 320 kpa but the whole table is filled in? The OS tab is still Blank? Does this sound like...

Just for grins I even tried to change the original base tune to SD then open it in 2.25 and it's the same story.

I completely deleted the version I had and re downloaded, re installed 2.25 and there is no change. It's still blank under OS and no change in the VE table.

I've read the guide on changing to SD OS but it's not working like the guide. I'm using 2.25 because I needed to do a transmission segment swap, I clicked on 3 bar SD and now under the OS tab it's...

Now I feel like an idiot, I guess I just thought it was an update to 2.24 or I would have looked harder for it. Thank you.

It still shows 2.24 in the infolog and segment swap is not an option.

I hope someone can help because tech support has stopped responding to me on this problem. I've been trying to download the 2.25 beta version so I can do a segment swap. I've done the download, I've...

Ok so one last question on this, I'm going to a speed density tune for a turbo. Should I do the trans segment swap before or after I change OS?

Great thanks for the help.

So if I find a stock tune in the repository that has the segment swap done or with a 4L80e already I can use that?

I have an engine/ ecm from a 2006 6.0L Yukon that had a 4L60E and I'm changing to a 4L80E. I see people saying it needs to have a segment swap to make it work with the 80 but under transmission it...
