Welcome to planet earth...So, i got the motor settled back and wanted to experiment with that yuminashi/keihin 'plug and play' ecu that was mentioned a few weeks ago.
I stuffed it in and set the timing to zero on the PCV as i have no idea what the curve is on the new unit. fired it up and left the same fuel trims in the PCV as was in there with the old (stock) ecu.
Initially, it ran really rich. since the new ecu i am sure had a richer afr target, this made sense. so i set the cells across the board int eh auto tune trim tables to -5, and it then at least got rideable.
I have to say, the ecu learned very quickly. in the closed loop , the afrs were at 13-13.2 and hit targets in open loop very fast. The bike ran smoother as well, somewhat, and was atad more responsive. since there's no rev limiter in the ecu anymore, i set the fuel tables at 11k and up to 11 to act as a soft limiter, and retarded the timing back 3 degrees.
I need to get the idle sorted a bit, seems ok but not perfect, but thats about the only complaint so far.
my plan is to see if the PCV can now be used to tune the cells from 0-60 and not fight the ecu. i'm not sure. i'll get a solid map done, than test this later. BUT, the PCV/WB2 does play with the yuminashi/keihin ecu. IF it can do the closed loop area now as well, us legacy power commander users can now get full tunability in the full range of the map.
considering the -5 setting in the auto tune helped it settle done initially, i'm guessing it might actually work.
