There is what looks like a crank sensor. I don't have that motor apart in that area just yet. It's still really cold in the shed, so I find ways to procrastinate. There are also secondary valves in the intake that should open like the secondaries of a carburetor, or at high rpm, I can't say for sure...

Not even necessary. I took the cap off and saw just how simple it is. 2 cycles per revolution. 50% duty cycle. Yup, 1 half closed, 1 half open. Makes it kind of easy. Now this engine also has secondary valves for the long runners that open with electrically modulated vacuum servos. This engine also ...

The Beetle is actually a 2017 Pinkbeetle Convertible. There are only 480 left drive cars. Other than the rarity of it, there's not much to really like about it :P The yamaha motor is getting the FreeEms for sure, and that's whats going to be transplanted into something first, and it's looking like i...

Thank you, Fred. I got the motor and transmission home, despite the 10" of snow we got today, and pulling the motor into the shed on a sled. I got it all cleaned up and 'debrided'. I read some about the 'Jaguar' board, and I'll get one, unless I find something better, and with what I've found, ...

Ok let the story begin. Doing my own EFI system has always been a desire of mine. I have been following DIYEFI for years (probably some 10 years). Also I have always been a hobbiest programmer. Lately I have been getting into embedded systems and have even enrolled in a course. Most of my experience...
