Hooked up Profec E01 and hooked the rpm wire up right ... no rpm showing?
 

Whats going on here? The rpm is not showing up at all. I spliced the rpm wire the wire from the e01 unit and nothing at all?????

Are there some secrete setting or something that im missing?

and the throttle keeps bouncing from 0 to 100% no in between readings.

Connector 2, Wire B

I double checked the FSM and that seems to be the right pin. It connects to the tach signal wire for the stock ECU dealership diagnostic tool. are you looking at the engine harness from the BACK of the connector, the wire side? you're not using one of those awful vampire taps are you?

and your sig says you have a 2nd gen but you posted in the 3rd gen forum and you posted the 3rd gen pinout in that diagram. is this on an FD? If you have an FC, there is a tach signal wire coming off the trailing coilpack I think...

yes i have an fd as well. I was using one of those splice ckips (i think thats the vampire clip your talking about)

how would you splice in then? i als otried shoving thewire directly into the pin and nothing either?
