3.0 Duramax DEF consumption

[BJ Niceguy]

I got controller today but am a little over my head. Where do you find the PID code numbers so know how to add a gauge? Also since the boost gauge just goes to 15psi, is there a way to add a different one that goes higher?  Thanks for any help

Hard to say.  Need more info on what program you are using.  I use ODB Fusion and use the digital version of the gauges so it will go above the 15 psi of boost

i am using the software that came with the unit (just got unit today)

If it's like my app you hold down on the gauge and from there you can switch it to a digital one.  I used this video to setup mine.  Every app is going to be different

Push and hold the gauge, click on display configuration. Here you can change the minimum and the maximum.

You can also change the name and how many decimal points it has.

The only custom PID I added was for the current gear.

Everything else is in there or just might be named differently.

If you want the PID for the gear I have attached a screenshot you have to fill it out exactly like that.

To add a custom PID go to settings, user-defined PID, click okay and then you should see a menu icon and you can select new.

is the PID number 199a or 1199a? it is not clear on my screen Thanks

199a

which PID did you use on Regen to get the active / passive part?  Also do you see a PID or sensor for OIL Pressure (not temp). Since the water temp varies so much from factory gauge, thought it might be nice to see where the oil pressure is.

 

Thanks for gear setup. It took a little testing to figure I was not going fast enough to get to 10th LOL

I added DEF for the first time yesterday at 4,025 miles. I had one full bar remaining and it didn’t come full from the dealer. It was a little over half full when I got it. 

 

I picked up Blue DEF from autozone. Did you guys know it’s not actually blue?

Whoops my draft got deleted.

It uses a variable displacement oil pump. Dealership won't do anything unless the belt snaps or it sends frags through the engine. I don't know of a PID for it. GM is pretty good with their pressure gauges.

I raided PIDs from the L5P and Colorado kids.

It's called DPF regen status I just changed the title.
Never had a "level 2" Regen I assume that is the forced stationary one.

I just refilled my DEF first time since I bought the truck. 5300 miles exactly. Put 5gallons in and it over flowed a little at the end. About 750 miles of the 5300 was towing a 5,000 trailer.

Not sure what is going on with my gauge, but I have 3600 miles on mine and it was down two bars on the DEF gauge and all of the sudden today it is sitting at full on the DEF gauge.  I'm not sure why it is showing that since I haven't filled it.

"range gauge"

It's supposed to be a tool for you to estimate how far you can go before you need to refill based on recent driving history.

I get its a "range gauge" but what I don't get why it would be down two bars for a month and then jump to full
