Gryphon asking for tire size in (mm). I have 35's....... What is correct mm setting......i tried on a calculatins site but doesnt seem right

 

Put in what it says, then go out and compare the Gryphon speed to a GPS, adjust as necessary to make them correspond.

 

35" to mm is like 889mm.......the gryphon doesnt go that low

 

It's looking for circumference, not height. For a 35, start with 2792mm, and then do what glc suggested.

 

Thanx fellas....reliable info as always on here

 

At 2792, im showing a little faster than actual speed....should i go up or down on the # to get it more acurate....im thinking down towards 2650??

 

Yeah, I think a smaller number is required if it is showing faster than actual speed. I may be wrong on that.

At any rate, I would make changes of no more than 100mm at a time while you're getting it calibrated...a drastic change may freak out your PCM and make the truck do strange things.

 

Thanx netwurk....100mm increments is exactly what i had in mind......other than this calibration, im thoroughly impressed with this programmer....easily noticeable gains even just on the canned tunes

 

Yeah, the Gryphon canned tunes seem alot better than the original Edge canned tunes. I have an Edge Evo that I have had forever, and I recently updated it to a Gryphon.

The new canned tunes rock compared to the old ones.

I have two custom tunes ordered and can't wait to get them.

 

Waitin on my customs also
