did anyone here upgrade to the JB4 yet? they just (6/4) released a new software update that includes a MaxCool mode. i'm going to try it out on the 6/30 HPDE up at new hampshire

Water pump and fan will run at 100% duty when water temperature is between 160 and 202 degrees F. At 203 degrees F the DME ignores the fan command but appears to continue to overrun the water pump. We'll keep working on finding a way to extend the fan range upward to make the feature more useful.
