R32 GTR - Type 2 - Electric Fans

Post by jjtxaz24 » Mon Aug 03, 2020 3:41 pm

Hey guys,

Gonna swap the clutch fan set up on my 1991 GTR to 2 12" electric fans. I saw the pin out (#28) on my ECU that I wanna hook them up to with a relay. I was looking through the software and didnt see anywhere I can trigger or set the temperature to turn on the fans on. Can I do that with NISTune? I have a type 2. Thanks in advance.

Pin 28 is the coolant temp sensor signal input. There is no fan control output on the BNR32 GTR ECU

I believe from factory there is a thermoswitch in the driver's side of the radiator with a green plug

There is nothing from the ECU however looking at that particular diagram (R32 GTR ECCS)

Be very careful using thermos. Most of them won't move as much air as the factory viscous coupled fan.
