That's about all I can think of.....

Well - I've definitely got the correct wire (Connector #B135 Pin #17 right at the ECM.) What gauge wire should I be using?(any ideas).

And an excessive voltage drop would read 'lean'. As voltage increases to the 1v threshold from the sensor, the leaner the car is running. This the reason why when the circuit is open(ie unconnected), the gauge reads rich (0v).

I'm getting rid of it, but I'd still like to know whats going on with it... it should be half ass reading... which it's not even doing.

On a side note, has anyone used the Greddy E01 to monitor a wideband sensor?
