2021 Chevy 6.2 build

Post by glockman49 »

When will you have software out to cover the 2021 Suburban with a 6.2? These engines run like crap because they always seem to be in 4 cyl mode. My gas mileage has gone from 22 on the highway to 18.5 compared to what I got with my 2018 Yukon with a 6.2 with the gas mileage tune. These vehicles that are supposed to get better gas milieage end up with worse gas mileage the way they come from the factory. So much for reducing emissions.

Unfortunately the 21 SUV models use the new GM Global B communication system which is so far keeping everyone out.
We could flash the pcm on the bench but thats not a reasonable solution, and even if flashed on the bench you have OTA updates now that could just overwrite it, so we'll be busy trying to find a solution for a while.
We have a 21 Tahoe that we purchased for development, and we'll keep poking until we have something that works!

Man, we really need someone to come up with a way in to these 2020, 2021, & 2022 Suburbans and Tahoes. I lost 4 mpg since I have been unable to tune my 2022 Suburban over my 2018 model. Need to be able to shut off the GM's bs cylinder deactivation too. Help.

Are you guys any further along on this project to allow us to tune our newer GM vehicles? I now have a 23 Yukon xl with the 6.2. It gets horrible gas mileage because I can't tune it. These green weinies talk about what they are doing to be green and all they have done is make the vehicles use more gas than needed by going to this new format of over the air updates etc.
