Engine & Tranny problems 2

[Don Bradner]

From what Martin says, the HP and torque are derived from power curves based on
things like throttle position and rpm. Use the parameter editor and change the
Horsepower setting - put in a multiplier of 0.95. He says leave the torque
settings alone. The HP would not be reduced by the fan being on - the HP
reaching the wheels would, and there's no way for them to see that.

Headed up to Grayland State Beach on the Washington coast for a weekend
gathering of RV internet folks, then we'll be hanging around the Portland area
for awhile.
