And by .5" taller or shorter than, I meant for 35" cuz I know not all tires are exactly that. But .5" is about 12mm for reference so you can dial in a pretty close measurement.

 

Ok I see. What about gears, stock?

 

The Edge will retrieve your stock gears from the PCM so you should never have to change your gear ratio through the edge unless you actually swap out for different gears.

 

ok, well thanks for all the help! Gonna go program the truck.

 

NP! Let us know if you need any other help!

 

Hey Irish, I told you wrong man. I messed up in my calculations...
Sorry if I'm makin you program a second time but your actually going to want to put in 2792mm if your exactly 35"

Again sorry for the screw up.

 

I was thinking about getting one of these but are they hard to install? what did you end up paying for the unit?

 

I just reeceived mine from 5 star tuning, he asked all the questions over the phone and then custom tuned 3 programs for me. All I had to do was plug it in and hit a couple buttons and sit back and wait. It took about 30 mins from start to finish but that was also to download the stock program so I could return it to stock whenever.

 

NVM i just discovered it will not work on my truck cause i have manual transmission

 

The equation is for metric sizes like mine 275/70R17.
With a 35" tire, you just times by PI to get the curcumference, then convert that to MM's.
That's assuming your tire is exactly 35". and not accounting for wear or squish of the tread.
Check against a GPS, and lower the number till you get it dead on.

On page 8 of my book for the Evo CS, there is a half page writeup about using the programmer with a CAI. It explains how the CAI can make them run lean, the Edge can also make them run lean, and the 2004 and up trucks are known to already run lean from the factory.
Add them up and bad things can happen.

I looked for it on the online manuals on Edge's website, and it doesn't say much about them. Not like the warning that's printed in my book.

Do some reasearch it. There are tons of posts warning about it.
