What is the difference between a Yoshbox and a Power Commander (PC)?
The Power Commander (PC) comes in 2 flavors for the TL an PCII and PCIII. Both are integrated into the stock harness and remain in the bike. Both change duration for the fuel injectors. Both are controlled by fuel maps that you modify with your computer. Both are best when configured using a dyno. PCII vs PCIII; The PCII connects to your computer through a serial port, modifies the map in 1000RPM increments, and many pre-made maps are available for download. The PCIII connect via USB, connect to your computer via USB, maps in 500RPM increments (finer adjustment), can map each cylinder, but has fewer pre-made maps available. Yoshbox; Connect it to your bike, program the ECU (Electronic Control Unit) to adjust fuel mixture, then remove. Modifies mixture by adding percentages to the stock map in the ECU. You can then use the Yoshbox to map other bikes. The tuning increments are not as fine as the PC. No computer required.
