Scott,
It I bought this 2002 in April of this year with 5K on it. I am pretty sure it has been running rich for a while from the looks of the plugs. The map that you are running, is it a .map or a .djm file. I could only find .djm on the dynojet site. Since I have the serial version i am looking for a good .map file until i can upgrade to a new PCIII. Any suggestions?
Good morning!
Just thought I'd share some thoughts on the pc3 serial, .amp and .djm files etc etc.
What I did was I downloaded and installed the pc3 usb software onto my laptop so that I could open the .djm files and look at the fuel tables across the entire rpm range.
I too amd running amospro's map. What I did was create the amospro map in the pc3 serial software from scratch by simpy typing in the values for the rpm range that is supported in the serial software to make a .map file. So on one window have the usb software open (or print it out for that matter) and on the other window be typing in the values.
It will be obvious right away that the usb software has rpm range increments of ? 250 whereas the serial software is 500 rpm range increments. This is where I simple picked the values of the matching rpm range from the usb, and typed them into the serial map.
I mean the usb has obviously got the advantage with the rpm range fine tuning, but it seems to be working for me having transposed the values to the serial unit.
Further, once I loaded the map, adjusted the idle to between 950-1000ish, did some road testing and plugg checking I have it pretty much right in the zone running nice.
Far as the back firing, some of the pros on this site like woody "churchkey" will ask "WHEN" does it backfire? and he was instrumental in helping me tweek the map until the backfiring all but went away. I had to determine if it was backfiring during decell, or between shifts, or was it just my lazy throttle hand no backing off the throttle between shifts (up or down). By tweeking the map (adding or removing fuel) in certain rpm ranges has become quite the art form here. Several guys have become very good at it. My guess is you will be talking to them as well as they are always ready and willing to help with map questions and tweeks.
No doubt that custom dyno map will be the best thing in terms of a map for performance BUT in the mean time I have had very good success working with the folks here on the forum to get my bike running to what I feel is pretty smooth all around with decent power.
Keep firing the questions....lots of good knowledge out here!!!
Oh, and Merry Christmas!!
