Manually adjusting power commander map? (too rich)

[AKDMA]

I'm using another member's map right now that was done at about 1200 feet below my elevation and in turn is a bit rich. I've also added in a uni filter to my turn one box, which made the mixture considerably more rich. I don't have any tuners here in the mountains really, the one trusted guy pretty much advised me that since his dyno was in SC at a much lower level, I'd be better off waiting. In the meantime, I've considered just reducing all fuel parameters in the PC by a set figure, say 3. I'd obviously rather be too rich than too lean. What are you guys thoughts on this?

Send me your e-mail ...

I'm currently on your map Wingnutt. It's the closest to my elevation of the ones I have, but I have a considerable amount more filtration and 1200ish feet more elevation.

sorry to threadjack, but if anybody can help:
PCIII programmer module
DynoJet can help but I have to send it away for probably 2 weeks, which means no riding

I just googled elevation and I think you are on the right track.

I was thinking of making a few.

I just don't want to burn anything up by dropping the parameters too low and am a rookie when it comes to tuning.

Since it is an efi system, soundn't it compensate for changes in elevation?

[AKDMA]

I'm unsure. The major issue is likely my filter, which is considerably more restrictive.

It should, but the system can only do so much and be so accurate without a MAF or MAP sensor.

Even the PC3 has limited resolution, and fine tuning is not really an option. When I tuned my Cobra on the FAST system there was much greater resolution in the tables and more tuning parameters were available. I could tune for every 50 rpm, volumetric efficiency, cranking fuel, timing, etc.

they have a "baro" sensor which is a barometric pressure sensor. It should make corrections every time you key the ignition on and off. they don't make real time changes like a closed loop system would. our beautifully rudimentary open loop systems are much more barbaric and take a reading upon "ignition on" and scale appropriately. they do however scale real time by coolant temperature.

all that being said how rich are you and how are you measuring?

[AKDMA]

I'm not measuring, it's just noticeably less responsive since I've added the new filter. That's why I wouldn't want to make any major adjustments. It does seem to run better when hot though.

The ones Brett gave me work fine ?

[AKDMA]

Might be the environment you ride in or maybe you don't log as many miles. Myself and a few others have seen fine dust in the airbox. One member had to do a rebuild on his as a result of the scoring from this. I can't risk that kind of engine damage.

Oh SHIT... Now Everyone on zilla is going to figure out that I am just a poser

Hey Just... Check your PMs

Peace

Someone hooked me up with a map that's pretty close for my setup, so problem solved. But I'd like to mention that even on an airbox map that was fairly rich, just adjusting fuel by one increment manually on the PCIII in all ranges using the external buttons/LCD caused the bike to be very lean. Tons of popping. Glad I got a map that works nicely.
