Hi, I'm having fun setting up my snowbike and wondering what everyone thinks would be a good AFR table for my auto tune system. So far I have it ranging from 13.2 at the bottom end to 12.8 on top. In practice it's been leaning it quite a bit at 5000' altitude. Running strong, sometimes chuffs a bit getting it started particularly if I've stalled it somehow. I'm new to detailed tuning like this. So these tables are a little advanced for me. Speaking of advance, ignition is advanced on the PCV map I have in the top ranges of rpm/tp. Is there a way to tell what is safe amount of advance at these altitudes? Also, I've got the startup fuel box checked, and 10 seconds time with 15% fuel added. Is this a good idea? Would more fueling help the stalled restart performance? Sometimes I have to massage the throttle to get it started again when I feel it trying to catch.
