Has anyone installed any on the disableers on the 2023 silverados yet and if so how are they holding up.

There are none available that work with the 22 Refresh and up trucks.  The new trucks have a different computer architecture which GM calls Global B.  The system is encrypted with a key tied to your particular ECM.  Trifecta Performance has apparently unlocked one of them, but doesn't list it as an available service yet.  I have a feeling it is going to take a while.

 

I emailed Trifecta this morning to see if it is something they will be offering, and got a reply.

"Our market research suggests the price point would be higher than customers would be willing to pay for a standard performance calibration like you’re describing."  I asked about AFM/DFM disabling and a tune over stock.  Basically the cost per ECU in time to unlock it is thousands of dollars to get it done.

So doesn’t deal exactly with your question but with the pulsar. I keep throwing a check engine code “P0711”  trans temp sensor, which is a problem the dealers know about, my issue becomes when I remove my pulsar to take the truck in it clears the codes and they cannot replicate. Has anyone else had this issue?

No. Mine is a 2019 5.3 8spd. No issues with the Pulsar. One time after about a week the truck went goofy and acted like it didn’t recognize the FOB. Wouldn’t start. I panicked and unplugged the Pulsar and it started. Got home and plugged it back in and has worked flawlessly. I hadn’t owned the truck long so I’m not sure if I did something screwy…..

I contacted Range Technology and was told they are working on a new version for the refresh but couldn't give me a date of availability. So for now, I drive in L9 which keeps the engine in V8 mode.

Me comuniqué con Range Technology y me dijeron que están trabajando en una nueva versión para la actualización, pero no pudieron darme una fecha de disponibilidad. Por ahora, conduzco en L9, lo que mantiene el motor en modo V8. 

Seguro que manejando en l9 no se activa el dfm?

Question for bikerjon, what can't you stand about your DFM? I can'f even tell when mine is working. I  was using the Range on my 21 5.3 when I had a lifter failure. I am no longer using the Range as I feal it has no benefit and lowers the fuel mileage.

Cant stand DFM. I definitely can feel and hear when DFM engages especially now that I have piped the exhaust. I bought my truck with a 5.3L V-8 and I want it to run on all 8 cylinders ALL THE TIME! As far as gas mileage. If  I wanted good gas mileage I could buy a foreign car or an electric car or ride a bicycle or just walk everywhere I go. The minute Range Technology comes out with a DFM disabler I will have one.

Very sorry to hear about your lifter failure but I don't lose any sleep worrying about sh*t like that. I just drive my truck ride my bike and live my life.

      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.

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

      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?
