Wideband setup.

My friend has a 95 Civic DX, It has a B16A swap in it with GSR cams.
Its turboed with a 60 trim Turbonetics Turbo, SLS log mani, RC 750, Walboro 255lph, full 3" exhaust.
Well the problem Im having is im trying to set up his wideband and I cannot get my reading shown in S300 to match the gauge. The Wideband is a PLX M series with the control box. I tapped into the gray wire and attached it to D14 and unpluged the O2 sensor. I've played with the offset and still cannot get it to match when it does match its only at Idle. Im looking for the cal to post up. Any ideas as to what it may be? I did type WIDEBAND LAMBDA PARAMETERS in the content area and it explains everthing pretty good but at the end of the page it has a screen shown that I guess in v1.3.0. Is there a way to select the series/ type of gauge as shown on that page. Finally what do you all use for the voltage conversion table theres 3 block and im not sure what to type in im sure 0.0 is 10.1 and 5v is 20 but whats the proper input into the center one. Any help is appreciated.

Here the Cal. Its very choppy but he just really needs to get around town til he gets tuned and the ECU is not setup for vtec, his is currently getting fixed.

Use another input than D14 for wideband opertion eg. D10, D12, B6

Note that if the ELD input (D10) is used then R136 and R138 (US ECUs) may need to be removed.

Pin D12 can be used as a 0-5V analog input. Note that the ECU must have a 0.1uF capacitor in C42 for the ECU to read the voltage correctly.

Pin B6 can be used as a 0-5V analog input. Note that the ECU must have R2 and R3 removed or replaced with 1N4148 diodes
