Can the thermo fan on/off settings be adjusted to work with an 82 degree thermostat?

Yes we can.

In fact we recommend that when fitting a 82 degree thermostat that the thermofan on/off setting are altered in the tune to suit as this will prevent excessive heat soak in the engine/engine bay.

Keeping the engine cooler aids in power delivery, this is especially important in blown applications where excessively hot air intake temps quickly reduces torque as the engine management pulls out timing to prevent pinging.
