I installed a PowerCommander on my '05 Heritage this week along with Stage I upgrades. I loaded the appropriate map and everything is working well. I tried to use the "accelerator pump" software when I was connected to the bike while it was running and it could not detect the PC.

Anyone else have this problem? I also remember reading that the accelerator pump doesn't do anthing for Harleys because the "pump" functionality is already built into the stock ECM. So should I even bother with the accelerator pump?

Thanks,

wingnut79,


You install (save) the pump free download to the computer, connect to the PC III usb on the bike (motor off) after the upload (which will update the program you already have), when you open the Power Commander program you go to the tools menu, you can enable or dis-enable the pump, change the settings for the pump etc. Upload the map with the pump enabled and the settings you want (you can tinker around with them) without the bike running. Print the PDF below and take it to the bike and computer with you. Hope this helps and explains it better than I can.

I just got back from a test ride using some new accel pump settings and it really responds now. I can't address what comes with the stock ECM, but this really seems to add some kick.

After installing the application called "PCAccellPumpEnable.exe" connect via USB and plug in the 9v battery to the Power Commander. Turn on the ignition (NOT the engine), then run the new application. Select ENABLE the accel pump. Then exit that app. Now start the "Power Commander 3 USB.exe" application, go to tools/Accelerator Pump (John TN's attachment is a good reference). The doc contains a couple of good setting choices depending on your riding style.

I just got a 97" upgrade w/heads/cams/pipes/dyno but was still lagging or pinging on hills under load. So my mechanic suggested a setting that put 50% additional fuel for more revolutions... and man does it kick!
