Hi jbo, I've searched and was not able to succesfully figure out which wire the tach signal is on the eco so I can run it with my zeitronix unit.
I'm talking about the one that comes off the coil packs..
Thanks!

go to the dealership and ask the service dept for a pin out of the ecu wire harness with wire descriptions and that will tell you which wire goes to what, the wire color and its pin number.
