What have you done to your K2 today?

CamGTP · October 15, 2025

Yeah that doesn't make much sense. The fuel system is still the same on a 2014 Flex fuel Silverado and on a 2015+ non flex fuel truck. The injectors, lines, pump are all the same. It's just missing the sensor. Even the factory harness is on the frame for trucks all the way to 2018.

It's like 3 simple tables to change. Import the stoich table from a 2014 file, import the power enrichment commanded air fuel ratio for full throttle and import the timing table differences if required. The truck does everything else for you once enabled.

Something to consider. When I tuned my 2014 GMC. It had the flex fuel option. Using E-85 gave a bump in horsepower much like when you tuned for premium fuel. So I left the engine tune for regular gas. I tuned the transmission raised the shift points like I usually did with new trucks. I thought GM finally gave us some tools for performance. On trips I used regular gas around town E-85. If it wasn’t for cylinder deactivation I’d still had it.

Replaced my thermostat and sensor. Twice over the past couple of months the fans stayed on after shutting off the truck. Also noticed that the temp guage in the cluster was showing a temperature less than 210. Ordered OEM parts based on everyone's recommendations and got them installed yesterday. Makes a mess with all the fluid. Getting the clamps loose enough to get the tubes off was the only pain. Re-filled the collant to the line and let her sit over night. Had to put a little more coolant in this morning since the fluid settled. Drove it to get lunch and guage was back to 210.

Did you get it recalibrated? don't they always run at 210° on the oem gauge but it's really running at 185° to 190°ish? My 14 and my 18 read 210° on the oem gauge but run at 183° to 187° all day long. On my way to work.

Actually any time the needle is pointed directly at the 210⁰ mark, the temperature could be anywhere from 185⁰ to 220⁰. Once it even slightly moves down off the 210, it is actually falling from 185. If it rises above the 210 mark, it is already going higher than 220⁰. Having the needle steady during a range of temps, I think GM just wanted to lessen concerns about temperature variations.

Working on finding the right stuff to wirelessly hook the backup camera to my iPad also tossing around the idea of getting the wolfbox G900 tripro dash cam setup to replace my rearview mirror.

Yes. I didn't get on the train for all the android based aftermarket radios. I moved the radio screen down to my center console and I'm still in the process of physically having the ipad mounted in the radio spot. I don't get many days off a year so. Keeping my wife happy comes first then I get to work on the truck after I'm done with fixing things around the house and taking her on vacations.

Yesterday was a busy day. I was able to go home for the night. 25 miles from home the torque converter gave up in my 2014 gmc sierra. It had a good run 307,650 miles on that transmission.

So i dusted off the Dirty Max. Trusty L5P to the rescue to carry me back to work. Today i will be updating the software for the banks gauges and the Deringer tuner. As well as looking for a trustworthy place to rebuild my 6l80 transmission from the 2014 sierra.

So the million dollar question ! Did you change your trans fluid on a regular basis ? My dealer said he no longer believes changing the fluid makes any difference .

I have the G850 Pro & I love it, I believe it is the same as the G900 just without support for the bumper camera

I changed it according to the maintenance schedule. It was always still mostly red looking. Never had abnormal treasures in the pan. Also kept trans temp 180° or lower. Pulled trailer a few times. Manual 5th gear.

Yeah, I like that it comes with 3 cameras i have a retaining wall in front of my garage doors so I would like to actually see how close I can get to it for backing into the garage.
