Hi Guys,

I just bought a new truck but I kept my Intune. The powertrain in the HDs is basically unchanged since 2012 but the 2015 HDs are the new body style. Is the InTune compatible with a 2015 Silverado 2500 HD L96 6.0L and 6L90?

Thanks for the help,

When I install a tune to my truck I can hear clicking under the dash that sounds like relays while the tune is loading. Every once in a while It will make this sound when driving. Who knows what the heck it is?

Thanks Mike. Nothing changed? If that's the case I won't worry about it.

I just updated my inTune for the first time since feb of this year. I have not done any tuning since then. Have there been any updates to the tunes for my vehicle that would make me want to "retune"?

I had tool firmware 1r03i and now have 1r03m

I had the GM tune db 1r01q and now have 1r01t

I ...

Can I ask why you left DOD on? I get the same or better mileage than stock on my 08 vortec max running the 87 tune with DOD disabled. How many miles are on your truck and does it use any oil? Also, the tune will have no effect on oil pressure. Could it just be that you are paying more attention to ...

I see my InTune updated firmware from 1r03g to 1r03h. Anything note-worthy in the new release?

The TCM tune comes up after the ECM tune. Did it ask you to pick a TCM tune? The TM settings are in the TCM.

The torque reduction range now works like it should on my truck. Negative is less TM and positive is more TM.

Lew and Mike also verified this for me by looking at my tune files.

A update to my update..... The torque reduction range now works like it should. Negative is less TM and positive is more TM.

Hi Guys,

Running the firm shift tune with TM turned down all the way, my part throttle 1-2 shifts are excellent. Firm and fast. Even at 99% throttle the shifts hit hard like they should. At WOT things change. The 1-2 shift is much softer and slower. Even with the WOT shift firmness turned up to +20 ...

Awesome Mike. Thanks. Can you compare these 2 just to be sure? the standard LTW is again the canned firm shift and the TMN file has torque management at -20% for the 1-2 shift. Also, can you tell me if -20% is essentially the same as turning torque management completely off?

Thanks again,

-Eli

Hi Mike,

Several of us with 07+ GM trucks and 4 speed trannys are trying to figure out the torque management settings. I am going to post three files below. The first LTW file is the firm shift tune with no changes. The LTW file with TM in the name has a torque management adjustment made on the 1-2 ...

No. Update and reinstall.

Mike,

Did anything change between the 1t03gc file you posted and the 1r03g file that was released? I just updated my intune and it still says application version 1t03gc.

Is it in the auto-updater yet? If not, here is the file. Drag it to your intune drive and let the tool update.
