PowerCommanderin sivuilla sanotaan r-mallista seuraavaa:
"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."
