Hello

Looking for Fan and Tacho output.

We use the SQ6 ecu for a BMW S65 V8 engine so i use pin 81 of ecu (inj #11) and Tacho trigger enabled on Caltool software/Hardware setup/INJ 11, ECU81 also all wiring is ok. But Tachometer not working.

Also for a radiator fan we need a negative output from ECU for run a 12V DC normal relay like attached photo. Now we have an engine wiring from VAC Motorsport and connector for FAN( Pin number 32 from ECU / HB3A).

Thank you
