tach problems
The tach works sometimes and dies sometimes.
I have tracked it to the cpu. When i move the wires
it works, but because there are so many wire at the plug
i . Does anyone know which wire controls the tach at at the cpu plug?

i'll be looking at my rpm wire tonight; tach works but the rpm signal to my data logger died. I suspect a wire.
If you can wait, i'll tell you which it is

I believe it is the light blue wire with a tracer? but not 100%.

Ninja12,
mike's right, lt blue (no tracer) goes from ECU to the tach but i couldn't seem to find the number of the pin it goes to in the ECU.
BTW, my tach pulse to the data logger is fine, just needed to fiddle w/the wires a bit. note that rpm pickup i use for dyno and logger is stick coil #4, ECU pin #10 (black w/orange tracer), NOT the tach signal wire.
