But is this VAG, odd length on one window trigger signature necessary if you can pick the right edge already? Selecting the correct edge with this setup gives you 4 evenly divided triggers.
Maybe I'm missing what you're after but I'm not really seeing the benefit of setting up a specific trigger pattern for this besides knowing which cylinder it's on once it figures out the odd trigger.
I think if you're looking for accuracy you're ditching the distributor crank triggering because of its slop and using
a crank trigger anyways. If the crank trigger / rear main seal setup I mentioned / linked to fits your engine it's a relatively painless way to get accurate timing (but of course requires getting behind the flywheel to install it.) The distributor wheel could be modded to a one window if you need to use it as a cam pulse along with that crank trigger setup.

This should be separated out from the VAG vvt cam trigger / sync pulse that is at a quick glance similar but it's really not. That's a different story, that one is to be able to see what the vvt is doing at a finer resolution coupled with a crank trigger wheel if speedy can calculate it / make use of it for fine tuning vvt or possibly watching for misfires if that's in the cards for speedy.

Quick side-question - How reliable is the 36-1 system? I'd like to use it on the race engine (Suzuki G13B) , it runs to about 8,000 rpm and has a bit of vibration as there's a lot of weight removed from the crank.
I can run a TDC #1 sensor on a cam easily enough, but I'd like to avoid the extra complexity* if possible.

* If it's not on the car it doesn't weigh anything and can't break.

That's not suitable at all...

Not enough information to get accurate ignition timing.

You would be better off finding a new flywheel or making a trigger wheel. One or the other. You want 12-1 at least ideally or stick with OEM ignition.

Hello,

I would prefer not to modify the wheel, if for some reason down the track I want to sell the motor it won't run on a factory computer, be nice if it could be configured for speedunio to dectect this trigger wheel.

Thanks
Bruce
