Power commander question
For those of you who tune a PCIIIR using the buttons on the top of the unit I have two questions:
1) how many points of fuel does each bar represent?
2) what are the RPM divisions for low, mid and high?

1) approx .2 per bar
2) 0-33%,33-66%,66-100%

One more question: does each button modify the fuel from 0 to 100% throttle opening (i.e. adding .2 per number in all of the throttle opening positions in the given button range)? what I mean is: if its a zero map and you go up one bar on the high button do all the throttle position readings from 0 to 100% now effectively become 2(or is it 20?)from 66% rpm to 100% rpm?

Fish,
Here's the story. I went to get my new bike tuned (bought it from Cowboy, but it had no PCIIIR installed until I got it. 1270, Ti force, Muzzy high pressure fuel pump, etc, etc) with a map installed I had cobbled together using my timing preferences and the Ti Force map that I found online. I made a couple of changes to get the driveability where I wanted it, and then took it to be dyno'd so that I would know where the a/f ratio was (I'm always concerned about being too lean), and since we were so close with the map (and perhaps because the dyno guy was being stuborn...who knows), he adjusted the map with the buttons. The map is pretty much right on with the changes he made, but for my own purposes I want to have the numbers dialed into the map, and not modified with the buttons. I had assumed that the buttons would actually modify the map #'s, but I see now that it's a sort of modifier of those numbers....and I dislike that. I want to have it where I set the buttons to 0 and have the map numbers adjusted where I want them....but I need to know the magic number to modify the map with.

you never use buttons to tune a map.
useing the buttons is the same as a TFI

Fish,
Yeah I knew that at the time, but didn't know that the buttons were only a temporary modifier to the map information. I was a little leary this last time I showed up to get the bike mapped and the dyno guy that helped me during my first visit was not there. If I would have known that the buttons were only temporary I would have insisted that he use a laptop....hell, I could have brought my own laptop down to do the job.....if I would have known. The problem is that there is litereally no one else within a 3 hour radius of Edmonton to do the mapping. I think next time I will be calling Walt Healy in Calgary (apparently they are dynojet certified). The stupid thing is that all I wanted was a check of the a/f ratio to make sure that I didn't melt the damn engine down.
