Greddy Turbo Timer Issues

[custommx]

I just installed a greddy turbo timer in my car. Everything seems to work great except the timing features. It has features where it will tell you your 0-60, 0-100, 100-200, 100m 400m and the speed your car is going.... BUT. it seems to be horribly off. i'll be doing 100 kmph and it will be telling me i'm doing 160, and its giving me 11 second 400 m times when i'm just going down the street. I am thinking that it is because my car is in mph maybe, and my turbo timer is canadian... Does anybody know? Thanks

There is a set up menu where you have to calibrate the speed of your car with the timer's reading. Did you set it up?
