PC3 map question
I have a stock ECM, is there an advantage or negative to using the Stage 1 ECM map?

RE: PC3 map question
No, there would be no advantage to using an ECM that's been flashed with the Stage 1 download, nor would there be a disadvantage.
As long as the PCIII map is correct, it will make up any difference that having or not having the download in the ECM.

RE: PC3 map question
So I got my PC3 yesterday, bought it used from a fellow HDF'r, thanks!....(Wild Pigs slip-ons, Stock ECM and Screamin Eagle air filter), installed map M807-059, zeroed the throttle...bike runs good, very little pops, much cooler...
my question is, does anyone know if there's anything else i can do (short of a Dyno) to tweak it?...
no problems, i just want to make it better

RE: PC3 map question
With the PCIII you can adjust the map in any range rpm or throttle %. Most maps run on the rich side to keep things cooler than stock. Check your map and you can cut the higher numbers to give you a leaner mixture. Make small changes and ride for effect. You can tune for better mpg and for more power just by trial and error adjusting and make it run to suit your idea of how it should run. If you go to far with an adjustment it is simple to bump the numbers back to where you were before. When reducing fuel listen for pinging. If you hear pinging you have gone to far.

RE: PC3 map question
i think that if you use a MAP that figures in Stage 1 that you will get less fuel signal because it assumes the Stage 1 fuel values are being used. i found that playing with the MAP that best fits your situation provides better results. a big problem i found with the PC was the retarded timing they had built in. i advanced most negative settings 4 degrees and got much better performance.
