Hi,
just how many flywheel ring gear teeth are there on my 76 911? Any of you have a spare around the garage... feel like counting?

I'm tinkering a little with electronics / Data acquisition, and I want to tap into my Tach signal... I'd also appreciate the number of teeth on the diferential ring - for speed.

Also, Soon to come : a lambda sensor and eventually - I hope - Programmable Fuel Injection. This continuous injection stuff has got to go.

Thanks

Laurent
