I haven't updated this in a while.
I've had several nice 60-65 degree days(Sunday through today) after we had a short cold spell. I've been tweaking and tuning and today I did some WOT(wide open throttle) testing. I've got it right around 12 to 12.5:1 and BOY DOES IT RUN! 90 comes up QUICK! Must be the absolutely no restriction of the 48mm throttle plates. And there is no pinging at all, even running a bit leaner than with carbs. I copied my spark curve from Megajolt(converted the 10 x 10 table to 16 x 16).
I've still got some warm up work and stepper idle speed adjustments to do. And I've started playing with acceleration enrichment today. Still the AFR control is turned OFF, I've got to get it close first before that control gets engaged.
I'm strongly considering a couple local dyno places, one in particular as they have experience with Megasquirt and it's control program Tunerstudio. It isn't hilly enough close by my house to really load the engine going up hills for long periods. I live right near a river, curvy roads but flat. I could go to some hills, but I need to drive a half-hour to do it and then there would still be traffic and pedestrians to worry about.
I'm thinking a safer and quicker solution is a chassis dyno.
It's been bright and sunny out, but there are no leaves at all, not even buds yet. Makes finding some shade so I can tweak the tune and see the laptop a bit difficult...
