I happen to be rather envious of that particular vehicle! Though if I had it I'm not sure how long it would be before the cylinder head was swapped onto the Amazon.

I wish I could say I scoped it, that would have been much cooler. I wired the CAS up, fixed a ~300mm dia cam/crank timing wheel to it, and rotated it very slowly.

if you want to duplicate work for your own edification, look for the lines around 'correctEvent' and modify those if statements and contents thereof.

Thanks. I'll see if knowing where to look helps me out :)

OK, your method of figuring out the angles should be close enough at worst. I'll push my work up later today (probably, though very slow start, up at 1pm... sigh) and you can compare notes with what you did.

I got the bulk of it changed to be correct last night, but didn't suss out either the old or new variant of the blue tick. Maybe it was the wine. :-p

Ended up writing some corner-case fixes for the tip in enrich code that someone was having some drama with. He can work around it with data changes, but I wanted to serialise my thoughts ASAP. And now it's midnight. Sorry again. Maybe Tuesday night is *your* night :-)

Doing extra hours at work, and getting through chores at home, didn't touch any of the three software goals I had tonight. Maybe tomorrow will differ. Still waiting on your attempt, though :-)
