thats a good question, your not fitted with a SC, your turbo, so you just want the IAT2 to read. The parameters for the IAT2 are already programmed in, not sure that it has to be "turned on" necessarily, just that the ECU really wont use it for anything.

You maybe able to use the SC "fitted" to activate the IAT2 torque management settings and then program just to use spark cut based on IAT2 readings. Enabling the DTC's for IAT Sensor 2 may also help you out.
