[s-cars] CMPS signal shape (was Location of CPS?)

[Konstantine Bogach]

Ref:  UrS4 does not start.
I observed relative location (timing) of signals from CMPS (cam, I also 
use Hall sensor term) and CKPS (crank) on my (running) 200tq and UrS4.  
200tq has perfect timing - TDC pulse is right on the middle of the 
negative pulse from Hall sensor, which is a rectangular pulse.  Bottom 
of the negative pulse is not horizontal but the pulse still have 
vertical front and tail (a better term should exist, I think).  The 
ratio of pulse widths is 8-10 to 1 (CMPS to CKPS).  On S4 TDC this ratio 
wa s 2-3:1.  This is just visually, I did not measure the width.
  But I can not call signal from S4's Hall sensor a rectangular pulse.  
Here how it looked like:

            |
              \
                   \
__                 \_________
   |      /
   |    /
   |  /
   |/
   A      B     C

      ^ - location of the TDC pulse (betwee A and B) on S4.

In 200tq the bottom of the negative pulse looked like this:

            |
              \
                   \
__                 \_________
   |
   |
   |    _ --
   |_--
   A      B     C
        ^  - location of the TDC pulse

|AB| would be different on these two pics (different scale).
I was expecting to see TDC signal not aligned with CMPS signal and this 
would explain no start condition.  But looks like relative position of 
the pulses is good, but I don't know if the signal produced by CMPS on 
S4 is good.  Anyone has comments?
Also, anyone knows a source for fittings which can work with regular 
fuel pressure gauge from a FLAP.  The set I have has no fitting for S4 
(but I can use it on 200tq).   Maybe I don't have fuel pressure.  I can 
hear that fuel pump works though.
