have Lew fix the off speedo, mine is adjusted for tire size, I let Lew know what height I needed it changed to and he added it in the custom tune.

i like it.
the main thing i like is telling the transmission how to downshift.... like: to drop to 1st gear, at 40mph, that way when i slow down to take a turn i can really LAUNCH out of it again.

says on your screenshot not compatible with intune products

Wondering about the Fusions myself, wife just picked up a low mile 2013 SE Eco-boost 2.0 I see the focus listed with the same motor. Is it compatible with the fusion?

Something is now right to have to it off that far

mine read 4.5 miles off after changing tire size and putting the new tire size in the tuner. I read on another forum to put in tire height. I used a tire size calculator and figured out what size height to use (more than an inch shorter than actual size). Anyways I put in different sizes until I ...

I Got my tuner back yesterday and gave support a call to get it set up with stock tune and such. I talked to Richard and I have to say I am very happy with the customer support I received. Everything is all good now
