Has anyone hooked this up? I hooked up an Autometer tach to the signal wire from the CKP and it reads way high and is jumpy. I read somewhere that the CKP tone ring is 32 tooth. Can anyone verify this for me? Also I believe that it is a 5v signal and the autometer tach says it requires a 12v. I have come up with a small circuit that boosts the 5v signal to a 12v signal and divides it by 4. I had it working at work where I have an oscilloscope but I haven't been able to try it out in the car yet to see what happens. I am waiting for one more part to come in the mail before I can do that. Just wondering if anyone else has tried this and what the result was. I just don't want to cut and tie together all the coil wires and pay $70 dollars for the autometer adapter.
On another note, does anyone know if the speed signal from the rear differential that goes to the ABS controller and then to the PCM is changed by the ABS controller or is it the same signal passed right through?
Any input is appreciated.
