No tach after flow force cop install

Okay iv been forced to ask this question I’m running out of ideas.

Switched to Flowforce COP now I have no tach. I have jumped b/w & b/y wires from igniter and put a 1k resistor between ig and b+ in the diag port. Made sure tach out was switched on in MS3pro. Still no tach.

Anyone have any ideas?

I believe you need to connect the tachout circuit to the correct pin inside the ECU by adding one of the optional jumpers on the board (J5). The resistor in the diag port should not be required.
