I have a MSPNP2 on my 1.6 to 1.8L swapped miata and the car cranks and idles pretty well, however as the engine warms up the fan is not turning on. I have the 1.6L thermoswitch installed, I have grounded out the harness and the fan turns on, so I know the fan does work. Before the swap the fan functioned fine as well. I have messed with the settings in tunerstudio. The instructions that came with the PSP said PM4-Accel LED is what controlled the fan. I have changed the values to see if it would come on but still nothing. The car is warming up to about 200 or more degrees and no fan. Any ideas? Does something need to be wired or changed?

Just as an update. I spoke with DIYAutoTune and they said that sometimes the jumper inside the MSPNP can be disconnected and to take the ecu apart and check terminal J8.

So I did just that and the jumper on the J8 terminal was indeed not connected, so I connected it and now the fan functions properly.
