I bought a haltech dual channel wideband (HDCW), the one with the 2 trim pots, which i would like to install it on my 350z pro harness.
-now the HDCW has 5 wires:-
Red to ignition switch 12v+
2 Black identical in thickness to be mounted on chassis Ground.
white for channel1 (0-5v analog)
blue for channel2 (0-5v analog)
- Connection Method:
Now do i connect the White & Blue wire to the black 4 position AMP connector fitted to the patch harness and leave the Signal ground & the +13.8v Switched unconnected.
- O2 Wideband Calibration In ECU Manage:
is the voltage table on the o2 wideband tab which is provided with base map from haltech is for the HDCW voltage range, or i need to change, because I'm having hard time finding the HDCW voltage range table on the Internet and it is not provided in instruction paper provided with HDCW Kit.

Re: haltech dual channel wideband (HDCW) installation 350z
I connect the wideband to the switched 12v and ground on the connector you have shown. So, all five wires from the wideband controller would connect to the 4-pin connector.
The calibration for the wideband is 0V = 10:1 and 5V = 20:1.
The calibration for the wideband is 0V = 10:1 and 5V = 20:1.

Re: haltech dual channel wideband (HDCW) installation 350z
thanks for the calibration data
in regards to the 2 black ground wires it states that you should connect them to a chassis ground, i will not harm anything if i connect them to the signal ground ?

I connected the 2 ground wires to the chassis, and its working perfectly plus i connected the VEI dual band AFR Gauge, this gauge is terrific, specially with the filtering option it has.

Question about this calibration, do you select 10:1 and 20:1 then just linearize the points in between?

Yes.
