Hi.
Just installed a plugin unit into my GTiR MY90
I have hooked up the Vipec and managed to get the car running, but I have an issue with the Fans not turning on at any temp or even manual toggling the AUX 1 output from the VTS.
The only symptom It seems is if I toggle the Engine Fan output Signal on, the Cat Temp Light on the instrument cluster lights up instead of toggling the Fan relay.
(that is consistent and repeatable)
I have 12 volts to the the Fan relay which has tested good and continuity all the way back to the ECU on Pin 9 (Which is the listed AUX 1 Output on the Vipec install software).
Pulling my hair out.
Dave.
