I just sent my stock tune to get worked on. Is it OK for me to recalibrate my tire size right now or do I need to wait for the tune to get back before I can change anything?

 

I'm in the middle of the same process as you. I changed my tire size before installing the 3.3 tune. Maybe someone who knows the Predator tuner better than me will chirp in but I believe it will stay even after you install the 3.3 tune. Or you can just check it real quick after the install.

They should get that tune back to you pretty quick. I got mine emailed to me a 10:30PM. I was surprised to see it in my in box when I woke up.

 

So it won't screw anything up is what your saying

 

Not 100% sure, but I would think you could calibrate tire size independently of performance tune.

Question: Do our DiabloSport Predators still only adjust for tire size in half inch increments, or have they upgraded the firmware to allow for quarter inch adjustments like the rest of the world?

 

Correct - don't load a tune, only make non-tune related changes (tire size being one of those options).

 

Thank you for the input

 

I just got this tuner two weeks ago and it is still half inch increments.

 

Just a heads-up, but like bubba, I've noticed my settings will change if I replace the tune.
