Just a note to say I tuned my wife's 2012 Vegas 8-Ball yesterday. WOW. I have a PCV and auto tune. Also have the factory swept pipes. I know "they are the worst". We don't care. It's about the look and sound we wanted. We don't want "loud" pipes.
That being said I started with the pcv tune for the Vic swept pipes and filter package.
The bike would surge below 2,000 and it was lazy to rev even in neutral. I checked the A/F and the complete map was set to 13.4 as leanest and 13.0 richest.
My change was to set the A/F to [email protected]
2%,5% ,10%,20% throttle.
40% was set to 13.5 1,250-2,000, then 13.2 2250-3750 and 13.0 from 4,000 up.
I also added 6* timing everywhere.
This is just a quick info for the tune, much more detail, but I hope you get the picture.
All I can say is WOW. The low-end grunt is amazing. Throttle response has improved. Bucking and surging are 90% gone and the backfiring on decell pretty much gone away.
The bike seems louder a bit thru the pipes. That could be the butt dyno.
I've been tuning cars/bikes over 40 years. Dyno stuff for last 25.
I used a temp gun on the bike and the rear cyl was 10*-15* hotter @ idle after a hard ride then 5 min idle to see how hot it would be.
I'll go out to-day to play a bit more.
