Unfortunately, unlike the Audi's and VW's, you cannot adjust this setting from within the PST2 (MAYBE the PIWIS has this functionality, but I don't know as I don't have one). I am working with Revo on a custom flash for my 3.8, and I have asked them to write in functionality for turning on the fans at a lower temp, but don't have an exact answer back regarding whether or not they can do this.

I'd be careful about hard wiring the fans, as I can see that pissing off the DME if the fans are on and it didn't they they were.

While the lower temp thermostat certainly helps, the real solution to keeping the temps down is to turn on those fans sooner whenever the car doesn't have enough airflow through the rads.
