The Apexi default is the factory standard wheel circumference.

If your wheel differs from this you have to enter a correction in the setup screen. You need to actually measure your wheel circumference . If you set up with wrong info obviously your readouts will be wrong. Read the instructions again

You can download the RSM PDF from www.apexi-usa.com . It says that you divide the tyre diameter by the factory diameter and this is the "TIRE:" adjustment that goes into the car select section.

Probably 110%

If this isn't very clear just download the PDF.

i have the manual but its in japanese,i think ill go and do a course in japanese, hahaha, so i went to that website, but it aint that clear on measuring the wheel, is it the whole wheel you measure, including tyre, or just rim??

cause on my last 33 the "tyre adj" in the RSM was set to 103% and that had 17" rims on it, i only used 103% as that was an example that they had in the english version of the manual, and that seemed ok.

Thanks for your help, and anymore would be appreciated.

to be really accurate measure the rolling diameter ie....from the ground to the wheel centre then multiply by 2
