Hi,
If anyone is preparing to have a custom map for their fuel injected bike that has a Power Commander, I have a new tool that could help dial in an exact A/F ratio at all %throttle positions at all RPM's.
I've created an Excel spreadsheet that auto calculates the exact number to input into the Power Commander for an A/F ratio set by the rider at a given %throttle setting after two runs on the dyno. To make it work I compared the ratio of change to each run then adding the ratios and dividing by them total number of runs. The run is not your ordinary 4th gear roll and cruise A/F ration check run. You would need to run the bike at every point of the %throttle positions at all RPM settings and hold it for about 5-10 seconds to get the exact A/F ratio for that position. Or roll the throttle to a given %throttle setting and record the A/F ratio through that RPM ban. That's about 400 positions total. I've included a screen shot of the front of the spreadsheet. I also plan on testing this on my bike and will report back once I have details.
Do I have any takers? If so, PM me and I'll send the spreadsheet with direction on what to do.
