Diablo inTune I-1000

[dinoedwards]

2003 Tahoe 5.3. inTune for tire size and economy mode back in 2015. Never put a custom tune on. Now it will not work just hunts when hooked up. I never did any updates on device.
Looking at a Trinity. Will the Trinity see inTune and be able to reset or delete for new device?

Might be a good question to ask DiabloSport directly. Why not try updating the I-1000 firmware first to see if that makes any difference?

Does an OBD scanner work properly on the truck?
