Well, it is an improvement over stock if tuned right, but the wideband o2 sensor based systems are way better.

Power Commanders have been in use for years. It provides an economical alternative to the HD SERT or SEST as it is called now. It is tunable or you can get a canned map for starters. The SEST will set you back about $600 plus d-tune. It has more ***** than the PCIII and nothing is added to the bike. I have no complaints with my PCIII and I am still using the canned map with some minor mods. The PCIV looks even more impressive especially since it is significantly smaller.

MoparDave's is about the best I've seen short of going back to a hub speedo and a custom ECU....which I guess they autotune really is.

The Tuneboy for it lets me play with timing, rev-limit, map engagement, speed limiter ect ect and for $100 more DEFINITELY improves it across the board. Of course since I have a Daytona motor in a Speed Triple, I had to do something as the airbox volumes are different enough that the PCs HAD no canned map and I'd rather tune the existing ECU then piggyback it and have one more thing to break.

All PCIII's do away with O2's. They run only with the map, the new PC is a closed loop system as is Thundermax. It's all in what you want and willing to pay $ for. I think if it wasn't for the EPA there would still be carbs on them

You are right about that, but I would still want my EFI, having experienced it first hand already. It is such an improvement in every way that I will, eventually convert my 69 Dodge over to EFI. The drivability improvements alone are worth it, not to mention the increase in fuel mileage and engine longevity.
