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

3000 on mine and only one notch of the DEF bar gone.

I have about 10,000 miles on mine. Probably just over two tanks of DEF. Minimal towing and hauling but mainly rural roads and around town Sent from my Pixel 2 using Tapatalk

When I got mine (Feb. 27th), it had less than 10 miles and the def was about half full. I had to fill the def(2.5 gals) up at about 2300 miles and it's still showing the same amount of def since then

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

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.

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.

      Gas fill door

      By newdude · Posted

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
