First off, hello to everybody on this forum. I've been on car forums since car forums started on the internet, but haven't done much on the Mercedes side. This being really only my second time playing with a Mercedes.

Does anybody know how many teeth are on the cam and crank trigger wheels and confirm that they are VR type sensors?

From what I can gather about the crank position sensor wheel, it looks like there is no separate trigger wheel and uses the flexplate teeth. Flexplate part number I believe is 1120320247, but I can't find a reference as to how many teeth are on it. I grabbed an electronic service manual off of ebay, but it is not very forthcoming or (perhaps just easy to use).

As for the type of sensor, I only see two wires on the crank sensor, which typically means VR type sensor as well.

The reason I'm asking is for setting up some aftermarket engine management. A friend of mine physically placed the M113K from a 03? SL55 into a '99 C43 AMG chassis... It's a level 10 kind of swap for his experience level unfortunately so I'm trying to help him finish off the swap and get it running. It has a long way to go, but will get it sorted yet...

Just for future reference (or for one of the established gurus to correct me) ....

cam sensor I get a 3 wire sensor part number A 0041536928, hall type.
Camshaft gear/sprocket 1120500204 - 36 teeth

Flywheel A1120320247 looks correct and I count 144 teeth. crank sensor is only two wire and thus likely VR type.
