Help in Pittsburgh

[paauto]

Would like to have my TPMS thresholds reduced because I run my tires at 50 front, 55 rear and am occasionally getting the "low pressure" warnings on the dash.  Had the truck into the dealer for the ECM/TCM re-flash and asked if they would do it.  They have the capability to do it, but refused citing federal law, etc.  Called another dealer and they said no.  

 

Anyone know of a dealer in the Pittsburgh area that will change the thresholds?  PM me if you do as i doubt they would want it in the open that they are doing this.

 

Thanks.

I'm in Canada, I was able to get my dealer to do it, dunno

Changing the pressures is not against the law, defeating the TPMS would be (for them).

Agree, but they don't see it that way unfortunately.

See if a local garage can help you, sometimes they can...

The Hypertech Max Energy 2.0 tuner (#2000) can adjust the TPMS thresholds, and I have a used, like new one to sell.  But for 2017 HD trucks, it appears to only work on 6.0 gas motor trucks.   I assume yours is a diesel?

[paauto]

Yes, diesel.  Any idea if there are any other tuners out there that would work on the diesel?

 

Thanks.

Thanks.

I think my local guy has a Snap-on that will adjust the pressures. Even try a local (read: mom and pop) tire shop...

My dealer did mine, but I made them as part of the sale...it's a daily driver, I don't need something to tell me a tire is low.

Requires a GM laptop/software.  

Talked with tech while mine being done --  using the wifi in truck and wifi in shop. 

 

Interesting side note is that now when I look at the myGMC app on the phone, the 'recommended tire pressures' it shows are the ones we programmed, not the ones on the door sticker.

 

And no, there are no tuners out for the L5P.

 There are 'foolers' out that plug into the harness and intercept sensor info send incorrect information in order to change ECM response.

I had the same problem. My dealer couldn't or wouldn't help.

So, I'm 0-5 with local dealers.  Thinking about buying a MongoosePro GM2 interface (cheapest interface i can find for about $450).  The Mongoose apparently acts like the Midi and will allow me to interface the truck to my laptop and pass codes thru.  Then buy a 3-day license to GDS2 for $100 and make the changes myself.  

 

Aside from being somewhat expensive, any thoughts on this approach?

 

 

[sdeeter19555]

There is a deal offered that fools the TPMS...it's to run aftermarket wheels without sensors. I've only seen it once, and just recently.

Another option...

OK, bit the bullet and bought the MongoosePro GM 2.  I'll give it a whirl with the GDS 2 software and see how it works.

Don’t forget to report back. Will you be able to remove the speed limiter as well?

[paauto]

Once I get it I'll snoop around and see what is modifiable.  I have a BMW M5 and had a guy get into the programming using BMW software.  On the BMW there are a ton of  (~50) different things that can be lit up/modified (essentially check boxes - so no re-mapping anything).  Mostly stuff that is de-activitated in the U.S. - e.g. I can (but don't) watch DVDs on my front screen, close windows with my key fob, monitor tire temperatures (apparently the TPMS sensors have thermometers in them), put a lot more functionality (radio, turn signals) in my HUD, remove lawyer messages, turn on high beam assist (if ordered from the factory it costs extra).  The list goes on.  

 

So, on the GMC wondering what is available outside the US.  I read somewhere that there is high beam assist but de-activated on the 2500.  Maybe we can figure how to light it up and other stuff.
