One more run to the top anybody good with adding used defined to this tune for flex or have another work around?

Bumping this back up to the top, really hoping for some help.....please!

I always seem to struggle with OS compatibility when it comes to P59 controllers. In this case I have am trying to add flex to an 06 Sierra that was a factory flex truck (virtual not a wired sensor)....

Been pulling my hair out on this and looking for anyone's insight if available. We put a PPG gearset in an 18 ZLE with different gearing than the stock ZL1 or ZLE. The gear ratios are close enough in...

I am working through the same issue without success.
07 TBSS with ECM OS: 12611938, TCM 24238660
I have wrote in the TCM OS 24235341 from a 07 Suburban w/E67 and it is always in 2nd gear, cluster...

I hear what you are saying with attempting to reprogram with the same OS, you can get around that by flashing an older OS with HPTuners then "updating" with Tis2wb. This is a situation where it will...

When we pre-program a T87a with Tis2web and send it to HPTuners for unlock there is not an issue reading and programming the car. I was told from HPTuners we can send in new unprogrammed TCM's for...

Had to delete all the channels out and rebuild my list and it started working.

Nailed it, car is wrapped up and runs flawless. Message me your address and I will send you a gift ;) Lifesaver!

So I have been using the same pro interface for about the last year with no issues. Recently I cannot get it to display in my Channels. I have added the MPVI2 PL A/D Input 1 (Red) to the channels and...

I will give it a run tomorrow and post results.

Alright, so I have one that is driving me nuts. Specs on the car are mystery cam, ported heads, Kong TVS2650, suppliment fuel kit, FIC142s, and some other small things. Crazy part is at full throttle...

Better question is what is it in reference too, the stock upper is a 2.5 and lower is a 8.0 so it should be 3.2 not 2.990. I adjust it as a percentage of increase.

Still looking for help on this, we cant be the only ones. I tried setting slip to a low value around 3-5 rpm and that stopped the aggressive rpm changes on lockup. Still looking for an answer to get...

Did you ever find a solution to this, I am working on the same setup with a Circle D triple that is going through the same situation.

I am working with a GM 525hp crate engine w/4L70E. It is a complete plug and play from GMPP. Everything is running well but it will not idle down when the vehicle is stopped. I have reduced my base...

I have done plenty that have not had issues, not really sure what definitively it is that corrupts the file and why it only effects certain cars.

Similarly I did a segment swap for a 4L80 in the...

Rick, I was able to adjust the TUTD tables without issue.

This is Carl, not Shane.

Yes, I worked off the stock tune with the newest version of 2.24 and was able to make it work as needed. Not sure what adjustment was made that prevented it from working in the first place but the...

Working on that right now, we will see how things go.

Update: I flashed the TCM only with the MDI using a stock new GM file and drove it completely unchanged from stock. It shifts through all the gears exactly like it should. I did include the scan data...

So here is a WOT run, on this run I started with the car in TUTD 3rd gear and after going WOT I shifted it into normal mode. DSteck you can see the Trans Shift Mode change from TUTD to WOT Normal....

Added to the new config, see below



I have seen a couple unique shifting issues that did not line up with what the tune was requesting as well. We will see what happens with this one, I am...

I did not log transmission fluid temperatures on this one. On a previous tune file I matched the hot shift speed with Normal and Pattern A and it still did it. To back up the orignial tune was a mail...

I have a 09 G8 GT that has an issue short shifting the 3-4 shift. At roughly 93mph the car will shift from 3rd directly into 5th gear. If you use the TUTD to put it in 4th gear it will also try to...
