Re: CAN VSS
I was also fighting VSS issues early on, thread here viewtopic.php?f=4&t=822 "4L60E VSS signal jumpy on roll-out".
I eventually got it working quite well, after experimenting with different resistor and capacitors in parallel. Getting a scope on it was key to see what I had to work with. The resistor knocked down my peak to peak voltage, and the capacitor smoothed out some small ripples that is coming from a 120VAC inverter that I use.
I too was thinking about using the MS3 VSS circuit, as it has a more advanced freq to digital circuit. But with a little experimenting, you can get MSShift to work good also.
As another data point, my first MS project was using uS to run a 1958 flat head Cushman scooter engine. I used a front wheel speed sensor off a 2001 Silverado pickup, which was looking at a custom made 60-1 cam wheel. The uS speed circuitry worked right out of the box, no tweaking. So I'm thinking you'll have good luck with the MS3 VSS.
