  1. Hello Adam,

    The BW turbo speed sensors already have a divide by 8 built-in to the electronics inside the connector.  So with just the 1/16 frequency divider circuit above you would have a frequency of 168Hz at 92044RPM.

    For better range you can use instead the Q2 output on the 4024 chip (usually pin 9) which is divide by 8 instead of 16 so will give you 336Hz at 92KRPM.  

    My first post as I'm planning my harness and sensors.

    I have a Jaquet sensor for my TSS PN: DSE 0606.02 T3HV which is the same as most of the Garrett sensors with the M6x.5 thread. I have ordered a TI CD4024BPWR counter (less than $1) and a board from Bellin Dynamic Systems to mount the counter and wires to. I was wondering if there may ever be a need to change the output pins (Q2, Q4, etc.) but I'm not sure which pins may be needed as I don't know their dividing count. 

    My plan was to se a 4 or 6 way connector so that I can bring the wires out of the 2042 ad repin the signal pin on the mating connector that runs the signal to the ECU. This will allow me to pot in the 4042 as an in line device.
