2015 GMC Sierra 6.2 - no options?

[robvas]

I can install the Diablotune and the truck runs great - however, 'adjustable parameters' and 'tune vehicle' seem to launch the same process on the tuner.

I don't get the ability to change the tire size, AFM off/on, throttle boost...none of that stuff. It just installs the canned tune and doesn't give me any options.

when you select the ECM tune to install, it will then ask you if you want to MODIFY the tune.. select YES/green checkmark to get into the adjustable parameters for the tune you selected...

I know how it works - it worked right on my last truck. It just never does that. I'll have to take some pictures to 'prove' it

I am having the same exact issue as described here. Hoping there is an update so I can turn v4 mode off....same truck and everything.

Mike posted a file in another thread that I had made, check it out https://www.diablosport.com/forum/viewt ... 13#p284413

I was able to adjust tire size and disable AFM and the speed limiter etc, give it a shot

thanks Rob, yes, the attached update should resolve this.
