Hi Bobby,

That is correct on the 13B CAS.  I hadn't specifically noted that those
two wires from the CAS needed to be connected together.  It was more of
a documentation change than a wiring change but could have caused some
confusion.

On the Renesis CAS only two wires are used.  Pin 22, white wire, is
connected to CAS pin B and pin 23, white/orange wire, is connected to
CAS pin A.  Wire colors refer to the shielded cable I use for the CAS.

Don,
 
I have an email from Bob White regarding a possible wiring change on the
13B CAS. "One of my customers found an error in the call out for the CAS
wiring.The white wire on the CAS cable needs to be connected to both the
white and white/black wires on the CAS. Please make a note of this
change in your instructions. This only applies to EC2 instructions that
say Mod 1 on the title page."

 

Bob can you clarify this? My EC2 manual is at the hanger. I do not
remember these wires being tied together on Marks but could be wrong.  
 
 
This is a quote from a Motec and Star Mazda document. Different ECU but
the gap they specify seems to fit what you are measuring at the stock
location. This also fits what Mark and I observed with a scope. As the
rpm's increase the peak to peak voltage increases. "The output of the eccentric shaft sensor is surface speed dependant and
is adversely effected by gap. Errors during cranking on a car that will
not start may be rectified by adjusting the sensor gap to be 0.030" ~
0.050" "

If I remember correctly the sensor mount is between the CAS and trigger
wheel. Do you have any washers between the CAS and mount that could be
removed to close the gap?

Bobby
