Hi Paul,
I know you've been traveling so not expecting much. Can you update me
on status of the ultra fast ignition system.

We've been busy testing the engine and would love to incorporate this
asap (even a beta). We are supposed to get 4 combustions per rotation
and we are typically getting only getting 1 to 3 per rotation and we
are now troubleshooting. We know we are getting the 4 sparks and now
are trying to determine any lag due to the ECU or misalignment with
the crank sensor. Over the next few days we will be testing the fuel
injection system and timing to make sure the issue is not on the fuel
side.


I would love to have the fast spark system installed as it would allow
multiple ignition for each event and reduce any issues with spark
timing. We are currently using a standard OEM automotive coil and it
seems to have no issues firing at 2200 Hz (550 RPM). I estimate that
it will be maxed out at about 3,750 Hz (ECU supplier thinks 4200 Hz
max). If we don't have a solution by then, I am considering two coils
and having each fire staggered at 180 degrees instead of every every
90 degrees now. That will allow me to go to ~7,500 RPM, and the next
step after that will be 4 coils each firing once per rotation. The
challenge is that it will be a bit of a pain having one (or two) spark
plugs driven by 2 to 4 coils, but I may not have a choice
Are you aware of any 2 to 1 spark plug wires?

I would appreciate an update on your development. If you want to send
update to all on the mail list, Please delete my email and send a
generic update not referencing the details above

We are working on the printed circuit board for the trigger wheel.

It still needs to be tested on my two rotor in the RV4.
That will need some more work to make it ready.


If your engine is running I might bring some up and test them on your
engine.

What town are you in?

No on the spark plug wires.

Paul, 2-into-1 is done in many Corvair installations with dual coils
feeding one distributor, using this part:
