Horsepower 1 and Kilowatts 1 are derived from the vehicle’s Engine Control Unit. 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 set via the menu
system:
Note
: In order for the KW1/HP1 or TRQ1 gauge to function, the “%Engine Load” gauge must
be supported on the vehicle.
Note
. Torque 1 & 2 are provided as competing methods of determining the torque output of the
engine. In general Torque 1 is likely to be more accurate. However, use which ever provides
the most reasonable results for your vehicle.

Torque 2 is derived based on the amount of energy being consumed by the engine and the
engine’s efficiency. By default the efficiency is assumed to be 24%. This means that only 24%
of the energy contained in the fuel actually produces power or torque output. 24% is a good
average for typical modern vehicles. This value can be adjusted if more specific information is
available via the menu system:
Note
. Torque 1 & 2 are provided as competing methods of determining the power output of the
engine. In general TRQ1 is likely to be more accurate. However, use which ever provides the
most reasonable results for your vehicle. Torque 2 is typically better for modified engines.

Raw output from the O2 sensor. 0 volts is equivalent of 100% lean fuel air mixture and 1.275
volts is 99.2% rich fuel air mixture. Bank1 is the cylinder bank with spark plug #1. Typically
only two O2 sensors are present, one on each bank. Some vehicles will support a wideband O2
sensor before the Catalytic converter and a narrow band after the Cat.
