I'm fairly sure it was around 40/50 when mine kicked in a few times going along the river on the way to Lake City, in the hilly windy roads. I had to kinda ride the brake a few times as the cars in front were slowing down a lot on the hills, and the assist would then kick in and turn on.

Just turn on tow/haul mode, that's what I do, its a more aggressive Assistive Grade Braking (AGB) The deceleration created by down shifting is really strong too, strong enough that you hardly need to use the brakes on those steep grades.

 

When traveling in Colorado I would sometimes initiate it since its easier to predict than AGB.

Gotta get used to these steep suckers here. I'll try the tow/haul mode today because we're gonna be traveling for sure.

I bet its gonna be real nice on that 8spd. On my 6spd w/3.42 sometimes it would drop to 3rd going 70mph. It sounded sick and really slowed the truck down, but I can imagine that the 8spd with closer gear ratios will be even better.

Just downshift... use your engine to brake rather than your brakes! the higher RPMs literally slow your truck down enough that you don't need to use your brakes at all, unless you need to come to a complete stop.

 

Tow/haul mode works, but not as good. You will know it's active as a message pops up in the DIC that says "Grade Assist".

 

Hill descent control is more so for off-roading in very slow speeds.

Yeah the more I drove yesterday I used manual mode and would downshift. My mom got scared thinking I was going to blow my truck up. Lolol

attachicon.gifOff into the wild blue yonder.jpg Here is a picture of my 2015 Chevy Silverado in deep ocean metallic blue paint, with a 6" suspension lift, 3" body lift and 37" tires. She came off the dealer lot like this.

Looks good! I plan to do a 3" BL and 37s after my 35s wear out. Not sure if imma go wider on the tires or stay at 12.5

Can you get us some more pictures? Side shots? And maybe even a wheel well measurement if you don't mind?[emoji106]

And do you know which lift and BL were used?

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

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Gas fill door

      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.

      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?
