Horsepower 1 is derived from the vehicle’s Engine Control Unit and based on a percentage of
maximum Torque. This gauge must first be configured by setting the maximum torque for the
target vehicle. The maximum torque is a common parameter that can be found by searching the
internet for the engine specification for your vehicle. The torque is commonly specified as a
Torque @ a particular RPM. For example, 200 ft.lbs @ 3200 RPM. The Maximum torque is
The torque may be entered in either fl.lbs or N.m
Note
For modified engines, alter the Torque value to represent the new estimated Torque.
Note
. Horsepower 1 & 2 are provided as competing methods of determining the power output
of the engine. In general HP1 is likely to be more accurate. However, use which ever provides
the most reasonable results for your vehicle.

%
Throttle P1
Abs Throttle Position 2
Throttle P2
The percentage that the throttle is open. This is the absolute output from the throttle position
sensor as a percent of the TP Sensor’s max value. The closed and wide open throttle positions
will likely not be equal to 0% and 100% respectively. For example, the physically closed
throttle position may correspond to an absolute position of 8%.
“Throttle Position 2” is for vehicles with a second throttle Position Sensor

Alternate to “% Engine Load” this gauge ranges from 0 to 95% for normally aspirated engines
and 0 to 400% for boosted engines. This gauge is linearly correlated to Brake Torque

Accel Pdl2
The percentage that the throttle Accelerator Pedal is pressed. This is the absolute output from
the accelerator pedal position sensor as a percent of the sensor’s max value. The un-pressed and
fully pressed positions will likely not be equal to 0% and 100% respectively. For example, the
physically un-pressed position may correspond to an absolute position of 8%.
Pedal Position 2 is for vehicles with a second throttle Position Sensor

Battery
Vehicle battery voltage is passed through a fuse and delivered to pin 16 of the vehicle’s OBDII
connector. UltraGauge measures this voltage and displays it as UltraGauge Battery Voltage.
For all intents and purposes UltraGauge Battery Voltage and the vehicle’s Battery voltage are
equivalent. As the battery voltage decreases, a point is reached where UltraGauge and the
vehicle’s computer will no longer function. Battery voltage accuracy is typ- 1% of
reading
