PCIII also does more than just adjust A/F in 225 areas. It can change the rev limiter and map the ignition advance in the same 225 areas. For most people that is all that will be necessary.

This is a misunderstood downside of the PCIII. It's true that it works in tandem with the ECM as an extra module in line, but that is not an issue for two reasons. First, the chances of a failure are slim, and if it does fail you can pull it out of the system and return it to the stock configuration. Since the O2-sensor eliminators can be retained, the EFI will not work in closed-loop mode and thus there will not be heat issues as would be the case if the sensors were active. I'm now running with 0's in most areas of the PCIII's cruise range, and if I remove the PCIII the A/F and ignition-advance in that range will not change. Areas changed by the PCIII will likely not work to peak efficiency for performance, e.g. full-throttle acceleration may suffer a bit without its influence, but there will be no catastrophic failure or an untenable situation where the bike self-destructs because of runaway heat, detonation, or other malady. Thus, I don't feel it is a disadvantage at all.

On the plus side, the PCIII has many more third-party combinations in the canned-map pool to choose from. SERT canned maps from HD are largely restricted to those composed of HD parts, so if you use third-party components (e.g. Rush mufflers with 1.75" baffles and K&N AC) you will likely require a dyno tune, unless you know someone who's had one that will share his map, which is an added expense. There are PCIII vendors who do hundreds of dyno tunes, thus providing a huge pool of resources to select from. In this case a dyno tune will not be required and the cost avoided. I still believe the PCIII purchased in this manner is the best bang-for-the-buck available at this time for people who plan on making a one-time change (mufflers, EFI, and AC) and staying with the result. SERT falls flat like the PCIII for people who plan on making incremental changes over time, like head work today, cam next month, compression increase even later on. In this case the wide-band closed-loop EFI-replacement options like DTT or T'Max may be preferable. By eliminating repeated dyno tunes these items may turn out to be the economical winners over both PCIII and SERT.

 

I have been told by my local dealer that they have had a lot of trouble with the power commander and that the moco will void the warranty. They recommand the SERT or Dobeck.
