If I'm reading my earlier emails, with the stock (180 TS) settings I think the fans come on around 190 degrees. With LMS custom for a 170 TS, they original had them come on at 180 and go off lower than that.
With a 170 TS the car likes to run 182-186 degrees on high end dipping to 178 and sometimes cooler. So I had them adjust the fans again to come on around 184 or so and go off 178 or 180.
I tried the 160 TS before this to see if that would help, but ended up where your at now and went back to a 170.
