Power Commander Use
Hello all,
I have a 2004 Ultra Classic and I was wondering if anyone is using this combination on their bikes. I have the Vance and Hines Oval Slip-Ons on stock head pipes, Screaming Eagle Stage I breather and a Power Commander III USB. I am using the download for the 2005 Ultra with those parts and it runs ok, but the ehaust pops a lot on decells. Is anyone using these parts and download and/or are you using another download? The bikes runs ok, but I think my '92 Softail with a stock EVO and S&S Super E caarb w/ thunderslide pulled harder.
Thanks for any input...

A friend of mine has a RK and he runs slip-ons, stage 1 aircleaner, and PCIIIusb. He tried different MAPs and then tweaked one until it ran how he wanted it. You can go into the MAP and adjust the fuel, etc. to get it right. [sm=icon_cheers.gif]

RE: Power Commander Use
Well your softtail is just a little lighter. Sounds like you may be a little lean on the low side. You can manually adjust the power commander by holding down all three buttons when you turn on the ignition, then you hold down the button to which you want to adjust and it either increases or decreases (I forget). You could look at the owners manual if you still have it, or visit the power commander site for better info.

Is there any reason why you didn't just go with a H-D Stage 1 Calibration Cartridge?
Unless you spend some dyno time, you are unlikely to get the Power Commander set for optimum performance and/or fuel economy.

Sincecrazy,
I agree. Sounds like a lean condition if it is popping. Either an air leak at some connection, or not enought fuel. Check the plugs. If they are real white, you are probably lean.
To do this, run at normal RPM, around 3,000 for a minute or two, then pull in the clutch, shut off the engine, coast to a stop, and check plugs. If you stop normally, by slowing down with the engine running, you might hit a place where the mixture is okay, and the plugs will not show a lean condition. You want to check for lean where the engine is normally ran.
Regards,
Bill

RE: Power Commander Use
The plug reading will not be the correct way to see if lean or not. Nowadays the fuel we get just sucks, it has a lot of oxidizers and cleaners to help control the pollution output, burn cleaner and keep the EPA happy, you really can't do the plug reading anymore due to the fuel and get an accurate reading.
You need to get the bike to a dyno tuner, (if you can find a good one) and the true way to tell if lean or not is with the AFR (air fuel ratio), this is done with oxygen sensors to the dyno from your bikes exhaust. The tuner will ( if he's good) get the ratio correct or near to correct as possible in all the rpm load ranges and the bike should run about as good as it will depending on what cam, compression ratio, etc. I would rather my bike run just a tad on the rich side than the lean side. Just my 2 cents.
