ECM/VEHICLE SPEED SENSOR

[klill001]

Has anyone out there seen or know of a way to access the ECM and change the tire sizes so the vehicle speed sensor reads true on the speedodometer? I know that on Chevy trucks the various aftermarket programmers allow one to do this, however I haven't found it listed in any aftermarket programmers for Nissan/Infiniti.
Thanks

yup, you need to go into the AV settings menu (turn off the radio, hold the settings button and turn the volume knob clockways). I think in those menus you can change tire size...

This is for a G37...

Thanks, I'll look into it this weekend. Hopefully it will work similar on the G35, if not I"ll know how to do it on my G37.
