Temperatures running mountains

Those new engines are the same as the mechanicals in a few ways. If you’re climbing and can’t accelerate the engine by stepping into it, you’re a gear too high. The engine basically pulls the whole grade over fuelling if your toes are in the carpet. If you can accelerate the engine off the pedal, the computer is fuelling the engine and will use less fuel even though it’s running faster. If it’s rugged out the engine might hang on to the gear it’s in, but will be using all the fuel in the world trying to rev itself up.

 

These new rigs do a real good job at fluctuating temps. Since it runs at ~220 degrees oil temp on a casual cruise, the rig does a great job of fluctuating the coolant temp and kicking the fan in and out. I seen my coolant fluctuate 25 degrees up n down, oil held steady 240-242 degrees at its max going up the grapevine. I took her up in the low side of 6th, just near 80k gross. She did a good job, had plenty of power left in that gear to climb faster but I kept her steady at 1500ish rpm the whole way.
