Lucky you... There no one here that can reflash my ECU only for the Temp ... They are Complete reflash... Messing with emission here is a $5000 Fine... SO no thanks... I am happy with my switch as I was with my old 1984 GPz Ninja 900R that is still running fine after 115K Miles and never saw those high 210 F temp...The first thing I did was become familiar with modern motorcycles.
When I did that, I learned that the "hot" temperatures were controled by the ecu. You manage the heat by setting the ecu up to be efficient instead of emissions compliant. I also didnt pretend that I had a problem, or dick around with an automatic fan. That fan is doing what it was programmed to do.
With both of my bikes, I had a trusted professional reflash their ECU's. I also added a full exhaust ( no more cat) . Guess what? No more pretend heat issues.
New one, what you are saying makes good sense. However, you dont need that second switch when you are able to re-program the original switch.
