Yes I have been trying to program my new truck. All i can change is tire size. If I change anything else I loose throttle. I have tried easytune and advance tune. Any help would be appreciated/

Thanks

I had the same problem.. After trying many things I figured out how to fix it.. I Returned the Diablosport to Summit and got a buddy to tune the truck with HPtuners... WAY Better Now.

Thanks for the response.

We'll have a fix for this shortly, sorry for the bug.
If you want anything adjusted for now please feel free to post a copy of the tunes from your i2 drive and let me know what you need changed.

Thanks

Is your trouble in an 8 speed truck or a 6 speed truck?

I've read that the 8 speed isn't supported yet, but that the 6 speed is. I'm asking because I own a 6 speed 2016 and am pondering purchasing one for myself, but not if it's still buggy... then I'll wait it out, but it will definitely be an i2, seems to me that it's the best in the market right now.

Mine is a 8 speed, but I just skip that for now. I believe they will get it fixed. Just look at dodge you have to replace the pcm to program it.

Here is the file. I would like the 87 tune, speedometer for 34.52, and no speed limit if possible.


Thanks

My 2016 GMC Denali 5.3l is doing the same thing. I was told today there would be an update within the next week.

I just received my tuner yesterday and and tried to install it, I get a messege that says "There are control units in this vehicle that are not currently supported but can be read...." If I select YES then it said cannot be read. If I select NO then I can install the tune but it disables my throttle. I have a 2016 Chevy Silverado, is this the problem you all have been having? And is there anything I need to do? Thanks.

you need to skip it when it says the message about the unsupported controller, because the 8 speed tranny is not supported, can't tune the tranny.. so skip that part..

[soldierscuba]

And when I skip that I have no throttle when I put the truck in gear.

"I restored my stock tune. Throttle works
I hook up tuner fallow its easy commands.
It does ask to read TCM and fails to do so every time.
I have loaded every easy tune and every advanced tune. Not changing anything.. Just loading any and every preset tune on this device. Still it takes the tune every time BUT it does not allow my throttle to work in reverse or in any drive gears. It will let me rev the throttle in Park though. Very odd to me.

That post was from NEMESIS-A/T on another thread, that is exactly what I am experiencing, I will try to copy and put the tunes on here tonight when I get home from work

email your tune files to [email protected] and let 'em know..

save this to the root of the i2 drive and let the device import it then try again.
