Help in Pittsburgh

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.

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?

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

 

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.

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

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.

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?

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?

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.

    • Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.       
    • We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper. 
    • Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money". 
    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
