Hi folks,
Was reading that the injection timing is "derived" from optical slots in the dizzy on 3.0 V6 applications. Was just wondering if the SMEC applies any advance or retard to this or whether it's more or less what directly sets the timing with the SMEC only varying the pulse width or what.
Also curious as to why there would be 6 slots when '88 is meant to be batch fire in pairs, not sequentially.
I'm curious because I want to screw with it, and try it earlier and later in the induction cycle to see if I can set up a condition that favours leaning out the mixture for economy. (i.e. whether slightly earlier or later firing can land the mixture closer to the plug)
So anyone have a good idea how this works? Certainly seems interesting now I know this that advancing the dizzy gives a good power boost on these motors, considering that that would appear to advance injector timing also.
thanks for any useful tidbits,
