Hi all,
would it be a lengthy and painful procedure to add and configure a 2 tooth trigger for a v2 engine?
it's a weird one


or just grind the old one off and start fresh with 12-1 or something like it.
I would be using no2c for spark, pickup sensor is 2 wire inductive

2 tooth would never be enough resolution for accurate ignition control...

[Lenny]

ok, what is the minimum for sequential spark just on crank sensor?

[theonewithin]

8-1 or better.

36-1 is really good.

[theonewithin]

Wait... You can't have sequential anything without a cam signal.

So the answer would be N/A.

Could you add more details of the engine/bike?

Like exact year and model?

Virago has inductive coils and VR sensor and two pips on the outside of the flywheel. It runs wasted spark but Ignitech do a programmable ignition system for these for around $136+taxes, so I'm not sure why OP is looking at Speeduino, unless he wants EFI.

My stock CDI died, and I just don't like readily available things, there is no adventure in that, too simple, engineers don't do simple

I will make a build thread when I receive NO2C and begin working on it. Lets consider this matter closed for now
