I'll need a log of the oscillation to see how that tune is working in the real world, but my prime suspect right now is that abrupt jump in the fuel table between 44 and 48 kPa. Also, that's not very much timing at full throttle.
Thanks, Matt.I will see about getting a log. Last few starts have been sublime - Either at full cold <50° F or full hot without heat soak >195°F I think the low full throttle timing is there to avoid the ping with a stock 1979 Cam and ~9.5:1 Compression. Short duration / low overlap stock cam bumps up the DCR a bit is my guess here.. I will see if I can get it to log and visit the oscillation nation. |
