Diablo Predator Tuner

[Ozzwoman9]

Sorry if this is in wrong forum.

Just got one of these and added the stock modified tune to it. Gonna be putting headers on soon and add a custom tune.

But for now...
Does anyone know where to go to change the tire size to adjust the speedo? Website says you should be able to change this with it and I can't find it on the tuner anywhere.

You can't change tire size, as I remember. I believe you have at adjust the tire rotation count.

What tire size did you go to?

Yeah he's right, you can't change the tire size, you have to figure out the number of revolutions...there's a calculator somewhere on line

I have 275-40-17 on the back right now (gonna change the fronts soon).

Kinda misleading that it says on their website that you can adjust for tire size changes. I might just have one of the guys on the diablo forum to write up a tune to adjust that as well once I get the headers on.

Thanks!

you can adjust for size changes, however the way to do that is in the Revs/mile setting as Jeremy posted, you may need to got to the nearest "5"
