Hondata

I have a tech edge 1.5. I have access to the NB output but there is only one WB output and that goes to the tech edge display. How do you wire the WB output to the ECU if you use the display?

I opened up the serial end that connects to the grey box and soldered on a new wire to the voltage output. When I connected that to the ECU I noticed that the A/F ratio that was showing in Hondata was significantly leaner than what was showing on the techedge display (yes I did check and recheck my custom voltage/ratio table and even confirmed the voltage that was showing in Hondata with a volt meter.

Please help...I am not sure if I should trust the display or Hondata.

Thanks,
David
