I was reading (and re-reading!) the initial trigger wheel timing for megasquirt. In my mind, the wording is backwards. That is not a big issue because there are many things in my mind that are backwards... So, looking at the picture, does my initial timing look ok? I am using the distributor as my main crank trigger.
Thanks in advance!

Re: type 3 megasquirt initial timing - distributor orientati
I'm assuming your picture is at #1 TDC.
You'd set for "Toothed Wheel", "Trigger Angle/Offset = 0", "Single Wheel with Missing Tooth", "Main wheel speed = CAM", "Number of Teeth = 24", "Number of Missing Teeth = 1", "Tooth #1 Angle = 60".
Your sensor is 30 degrees after Tooth #1 (aka Tooth #1 passes the sensor 30 degrees BTDC), but because you're on the cam, you have to double that value to get the crank angle degrees which is what that "Tooth #1 Angle" setting is asking for.

Oh man! That actually makes way more sense to me now! Thank you!
