Power Commander II
The Power Commander II was introduced in 1999 and featured the
latest surface mount electronics. Additional features were added
like the faceplate button adjustment. The Power Commander II also
allowed fuel and ignition adjustment on select models. The PCII
utilizes "sensor offset" technology to adjust the fuel
curve. Signals from the various sensors on the bike are monitored
by the PCII and these signals are recalculated and sent to the ECU
in order to achieve the required fuel curve.

Power Commander III
The Power Commander III was introduced in 2000 and is
externally similar to the PCII. The PCIII utilizes "direct
injector control" technology to control the fuel curve for
models that do not possess the appropriate sensors to allow
sufficient fuel adjustment using the PCII technology. The PCIII
takes the injector pulse from the ECU and changes the pulse width
signal to the injectors. This unit allows "Fuel Only"
adjustment.

Power Commander IIIr
The Power Commander IIIr was introduced in November 2000 and
utilizes the same "direct injector control" technology
as the PCIII. The "r" version contains additional
circuitry and in some cases, additional connectors, which allow
Ignition adjustment as well as fuel adjustment. Ignition
adjustments can provide very positive results on the race track,
where factors like special fuel and highly tuned engines are used.

computer.
This model also features an expansion port for future add-on
modules
like an ignition module.
