Surging and Timing
Surging and Timing I need some guidance to end my surging problems from 1000-1600 at low loads.
My base spark tables are at 20deg from 8-1200 down to .40g to help with the parking lot bucking under 1% throttle where main spark tables arent used, but it still bucks.
I've also tried adding and taking away timing on the main spark tables to help with the surging at cruise, still nothing.
I guess my question is, how do you know whether to take away or add more timing when surging occurs, and when does fueling come into play?
I've got my ltfts at -1 to -4 if that helps any.
Thanks for any help.
