10.11.3. Usage of different tires
The application of the ABS System of the 911 GT3 R has been carried out
with Michelin tires. Therefore, the stored tire circumference is valid for the
actual Michelin tires.
This circumference is
2037 mm on the front and
2230 mm on the rear
If different tires are used one has the possibility to adapt a different
circumference for the ABS system with MoTeC. This could be necessary
when tires from a different manufacturer are used. To change the tire
circumference the following steps are necessary:
•
Open the MoTeC dash manager and load the GT3 R configuration
• Go to Menu

Inputs

Constants / Remote Control
• A window with both circumferences appears
• By clicking on the shown circumference one can alter the value to
the desired one
• After the changes have been made, do not forget to save the
configuration and send the new configuration to the dash
A correction is necessary when the actual circumference value differ by
more than 5% from the above listed values. A correction of the values
when changing from slicks to wet tires is normally not necessary.
