[Diy_efi] Typical boosted ignition timings

[Marc Reviel]

The distributor was gutted and a simple sensor added for Sync Signal 
to the MoTeC. No advance/retard of any kind.  MoTeC also uses the 
60-2 factory crank trigger wheel.  Never any issues with the MoTeC 
working properly.

I did get some feedback from Todd at ProtoMotive. He did say they had 
to retard to 14 degrees @ 1 bar on 91 octane on an engine very 
similar to mine to be able to run on street gas.

Experimentally, I was arriving at 12 degrees @ 1.25b and Lambda set 
to .85 on 93 octane to get detonation-free on my engine.  That seemed 
a little too retarded at first, but considering Todd's experience, 
maybe that's just the way it is.

Have you worked much with engines similar to this one?
