In reviewing fuel pump controller circuit, it seems to be identical with the exception for pin 35 at the ECU which connects FP controller. I believe since the NA controller is not setup for the 6 volt speed the controller will not receive signal and therefore continue to run at the 8 and 12 Volts NA set up, so it should be okay to use a TT ECU with NA FP controller. If anyone has information to the contrary please let me know. In addition if anyone has pictures of NA & TT controller circuit board please post them.
