The GM one isn't approved yet for 2021 unless it was ordered and factory installed. Dealers cant put them on yet so they wont sell them right now.

Only for 2021?  I have it on my 2020.  I did the install myself (except the tune that was done by the dealership).  It came with a sticker I had to place under the hood to prove CARB compliance.  Seems strange it would be good one year, but not the next, and nothing changed.

Sounds like it’s only for 2021s right now. If it’s ordered and factory installed and delivered that way its fine, it’s just the dealer installed ones after purchase. 2019 and 2020 have CARB approval so not an issue. It sounds like it’s in process for 2021s so just a matter of time before it will be OK for a dealer to add on afterwards. Realistically you could probably install it anyway as no other CAI comes with a tune but those also advertise as also not being CARB client. I’m sure the CARB approval comes with some minor adjustments to AF ratios with the tune which is where the testing comes in and the delay in releasing it. I put intake and exhaust on almost everything I buy and never get things tuned unless it’s an OEM option.

 I just recently found out someone online found  part number 84789802 is CARB approved with an EO number from GM directly which includes an ECU flash in part of your part purchase done by the dealer.  Still searching for verification and I did ask the online Youtuber who posted the video where I can find it.

 

I've been scouring the net and nothing for the past 6 months.  Hopefully he's right.... Repost/reply if someone else in the thread locates or finds it online.  I will continue my search. 

 

Aside from that.... Its the K&N 57 Series OEM Performance Air Intakes 57-3108

Regarding CARB compliance, what's the big deal?  The current test in California is really nothing more than looking for a CEL light.  At least, that's how it was for my test in October, so please correct me if I'm wrong.  I was in and out in a matter of minutes.  Iirc, the guy hooked up an OBD2 scanner, and that was it.  Gave me a printout showing I passed, which I mailed to my home state to prove compliance.  I live in San Diego, but a Utah resident.  I was prepared to point out the CARB compliance sticker, but the tester never opened my hood.

      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?
