Hoping to find a different calibration to load into this 2018 GMC Savanna transmission.
VIN# is 1GTW7AFGXJ1911495

This trans is running from a TCM 2650 controller in a 2006 GMC Sierra.

I went through the updates again this AM.
same problems.
Then I uninstalled 2.2.2, reinstalled 2.2.0, things are working normally.
I'll look into it more later.
Updates took about 20 minutes.

check for power at the obdII port.
on the trucks, the cigarette lighter fuse is shared with the port.

Same problem here.

I know several guys who plow with their trucks.

These 4l60s shift pretty slow between R and D.

Is there anything that can be done to get a quicker shift?

Here is a stock file from the 07...

Sure I can post up the tune.

Just to be clear, I was talking about the VCM CONTROLS IN THE SCANNER.
Not the tune.
I am sure you can change whatever you want in the tune.

I can get the tune...

OK
I'll get right on that.:)

I didn't realize it was gen 4

Thanks

BTW, I tried subtracting negative timing, but it didn't work:secret:

I was hoping to try a bit of timing and fuel on this truck to get an idea of what the potential is.

But, these controls are grayed out.

Most of the 99-06 trucks allow adding timing and AFR...

Or only when it's closed?

I remember another thread where this ws discussed.
The heat from the valve vaporizes the fuel better...

Anyone playing with this yet?

Got my 2.19 beta.
Thanks for getting it done so quickly.

FYI the only change that can be seen in HPT is the Idle startup friction airflow decay vs ECT.

Great,
Thanks Bill.
Looking forward to your progress with this.

Among a few speedbumps I encoutered with this truck today, i found no change in timing when using VCM controls.
I tried +timing, and -timing, and absolute, with no effect on the actual timing.

Hey guys,
Well, I did a read entire on his truck after he got it back from the dealer.
everything went fine, until I saved the file, I got a message that I cannot modify the file, and to contact...

I have tuned a friends truck and he is going to get the new flex fuel update on monday.
Anyone know for sure if I will still be able to tune it afterward without buying more credits?

:doh: Mines been plugged in for at least a month.
Maybe I should rig up a switch too.

Trucker here too.

Hey Guys,
Thanks for all the input on this.:chug:
I just bought a PC. :)
I'm sure someone else is interested in this info besides me though.

Thank you very much.

I'll tackle this soon.

How about running a 2005 tune from exactly the same engine?

Does anyone have a 2006 truck with HPT that has the option, or has changed to, a 1 bar MAF enhanced OS, or made any other OS changes.

I...

Thanks for the input guys.
I am using a friends PC right now.
But, I will need to figure this out soon.
I'll post any success or not when I get time to try it on the mac.

Anyone know if I can run it without running XP? (hogs memory)
It's a G4 with Tiger OSX. We currently run Excel, and Word, and a few other windows programs.
