I also adjusted idle to 850 rpm.

I'm glad this was useful to you. In my climate radiator coolant temps were always a concern and I think this will keep the engine temp under control safer in the long run.

I was able to set the fan temp triggers to primary 186F (85C), and secondary to 193F (193F or roughly 90C). Basically, I just added 0.17 volts to the on/off fan relay triggers 1-4. I did not change fan relay trigger 5. Plan to reevaluate this during the colder season, if there is one in Texas.

I was resetting fan temp controls with trial and error and ended up very close to your suggested parameter. My primary is set at 186F or 85C, with my secondary set for 193F or roughly 90C. Good to know I was right around your suggested low point in the range.

Will look at the idle rpm next.

Thank you!

I am wondering if someone could help me understand the radiator fan control settings. I see a primary and secondary trigger in the ECU definitions, but there are five on/off relay coolant temp points as well. What would control the fan speed?

Thanks

So with the Personal Lite version, can I set a temperate to trigger the fans below the stock temp?
