I'm happy to confirm another happy customer with that map, Caleb. It is a growing list. Please keep us informed of any tweaks to the timing you run across that might be attributed to the EFI. If you do improve on it, then I'll incorporate those changes into the programming for the Rocket's first flight (still months away, I'm afraid).

Have you done any testing to confirm the optimum LOP ignition advance yet? Mine was 3 degrees, but that was with Bendix injection. Interested to see what differences in ignition timing the better atomization of the EFI gives you (if any).

And for all the rest of you, I've been hesitant to publish this map. You should know that it relies heavily on MAP as the primary tuning aid and as such is is pretty conservative at high power, and very aggressive at idle. Anyone who grew up messing with 60's musclecars will recognize the similarity to the logic. Anyway, if there is a fault to this particular method it will be found at flight RPM and low throttle setting such as a letdown/approach to the pattern - be prepared to see 40 degrees advance in the window. Wont hurt anything, but its just a byproduct of the programming method.

Anybody contemplating using this map is welcome to contact me here or via PM.
