2005 FJR Power Commander III

[Ack535]

OK guys, this whole PC III thing is new to me.

I purchased a 2005 FJR 1300 with a PC III installed. Question is, I have no idea what mapping program the P.O. used, neither does he... The bike is running with a K & N filter and a set of 2 brothers pipes. Bike seems to start and run fine, idles down to about 1,000 RPM's when warmed up.

Any suggestions, or just leave well enough alone...

I think you can connect a laptop with the correct software (free download) and check to see what program is in it.,,  I think

Took the P/C off my FJR, make the bike smoother but the fuel millage sucked

[FJRmgm]

the greatly reduced gas mileage is why I have never put a PC III on my '05 FJR.

PC dropped my fuel mileage enough to make it an issue so I went back to stock.

I have stock pipes, K&N filter and the "Wally Smoothness" map in my PCIII.  I lost about 3-4 mpg, but the bike is snappier and runs a little cooler.

That was my experience as well. A good trade if you ask me.

One thing you can do is find the rpm you generally cruise at.  Lean the lower load settings back to stock.

I've never found a pcIII to use more fuel on my 02' or 06' R1.

Say 5% load @ 4k rpm adds 8% fuel. Simply put it back to 0 or lower it to 2 or 4 or....

Now the higher loads are why you'd want to run a pcIII in the first place. Like 20% and up. part throttle roll-ons and such.

pcIII smooth the bike out, can make it run better, cooler and if you're a 65mph in 5th gear kinda guy @ 3k rpm... you can tune it. Running a pcIII doesn't have to add fuel everywhere. You're the boss.  Unless of course you need fuel due to heavy mods.

I have had a PC on several bikes and it always resulted in loss of fuel ecomony.

I hope that preference is based solely on price.

The new one actually handles and stops. The old one... well, it went down the road like the dickens. It needed work to handle well enough.

Power commander handles adn stops welll???

Properly programmed PC can give more power and better fuel economy.It is possible to lean out 2,5 and 10 % of throttle in lower half of the powerband,it should improve cruising fuel economy.

The problem is many of maps available from the Dynojet follow the simplest route,they are tuned to certain A/F ratio,let`s say 14.7 at cruise and light loads and progressively richer at heavier throttle.It is not necessarily the best for the fuel economy and performance.It depends.

Personally I`ve always improved fuel economy with installation of PC and playing with the maps.
