With Cobb's new CCF Rom structure, you can perform the adaptation directly from the AccessPort. By selecting the “Turbine Actuator Voltage” monitor in your gauges, you can monitor the voltage in order to set your wastegate voltage (~3.9-4.1VDC in most cases), and then
utilize the “Wastegate Adaptation” setting in the troubleshooting section to
set your adapted voltage. To use for setting is38 wastegate voltage, the car
just needs to be in the ACC/ON position (not running). You can then manually
set your voltage, and then in the troubleshooting menu, perform the wastegate
adaptation. To use for setting the is20 wastegate voltage, the car needs to be cycled into the ON (not running) position. The voltage is then displayed as the base voltage, and then after the car is on for more than 10 or so seconds it reduces to a resting voltage. Note that you will need to repeat this action a few times until you reach the desired voltage. Then perform the wastegate adaptation as above.
