thanks, appreciate your help.

ok, thanks. what about the lost dvd? is it needed to for setting up for a different vehicle on a different computer? I forgot what was on it.

I want to make sure I properly unmarry my trinity, so that I can use it on a different vehicle. What do I need to do?

I lost my dvd that came with the trinity. Do I need it to set up on a different computer with a different vehicle?

ok, thanks for your help.

do i have to reinstall the tune or is it modified on my currently installed tune?

i'm running v.1r09f

ok, so it says failed after trying to callibrate like you said.

I'll get back to you with the exact error msg

I still can't change my tire size on my trinity. I've tried by diameter and by metric size numerous times. Is there a fix for this?

i'm loving my ds trinity tune so far.... Everything is working well, but i'm unable to calibrate tire size.
is there an update that will allow us to callibrate tire size yet?

i installed the 93 tune with no problem....
but i'm unable to install the 93 tune with mds off or traction control off.
it also won't allow me to change my tire size with stock tune or 93 tune.
any advice or ideas?
