My buddy just swapped to a SLP 160 degree thermostat in his 2012 silverado 6.2L. What do we need to change the fan settings to... (if we do) for EFI Live.

Right now he says its still running at the factory settings. I looked in his file and his fan speed is variable (percentage based) off of his coolant temp. It doesnt even start to work until 192 deg F. im only used to high/low speed fan settings. should this be adjusted at all, if is so what to?

Thanks in advance,
MJ
