This fixed the problem I had with the car wanting to die at stops - coming down from RPM. And it seems to run better overall, BUT, now when I hit about 33 mph, it starts to die.
I've only driven it once, but it seems like I can drive right at the 33ish mark, and the car will run great below and as soon as I go over, start -I think- cutting spark. And if I stay over the mark, the engine will die.
I put 5 magnets evenly spaced (probably not exactly) on the drive shaft. I'm thinking it's the wrong number.
Anybody know how to figure the right number?
For the Vanagon, the axle mounting bracket has 5 readings per rotation.
The subie speedo VSS's have 4 readings (which is 4000 pulses per mile) (how many rotations/mile for the driveshaft?)
That's about all I know. I don't know where to start for mathing it, so I might just have to try 4 magnets and see what happens...
