I love my Vic , but I find it highly annoying sometimes to have to ride in a way that is conducive to not causing a pop or outright backfire... I have had 10 bikes with exhaust and programmers, none of them ever back fired... I understand why the Vics back fire, but what a pain in the ass.....
Gunslinger helped me with my popping but giving me some tips on things to look at based on his experience. He also took me to school on the PC-V/AT. Although there is more to learn, he helped me to understand the basic methodology of the unit.
I read all of the posts and tried things that worked for others but it did not help me. My bike still sounded like I was being shot at. Here is what I did:
1. Removed any values in the ignition table on the PCV. It now contains 0's only.
2. Removed any values in the cells on the fuel map for throttle position 2% - 100% at 500, 750 and 1000 RPM.
3. Place -20 in the 750, 1000 and 1250 cell at the 0% throttle position in the fuel map.
4. Place 0's in the 500, 1500 - redline cells at the 0% throttle position in the fuel map.
Major change for me. I only get a pop at 2800 and 3000 RPMs if I hold it there to long. I am working to resolve that now. Otherwise no popping at all.
This may or may not work for you but I can get on it or get off and not worry about that popping like before. Others may not agree with what I have done and how I did it. However, it works for me.
Thanks again Gunslinger!!!!!!!!!!!!!!!!
