Hondata

Cool new features. Wideband closed loop very interesting will see if I can get better fuel economy

afaik the wideband input is display only.

Closed loop adjustment is still made via the narrowband input on the ECU. Some widebands like the PLX do a simluated narrowband so you only need to run one o2 sensor.

I recently purchased one of these and connected it to my Hondata S300.

The analog wideband output works fine (ELD D10), but the simulated narrowband (attatched to stock O2 signal D14) sends a voltage outside the narrowband range (2.4-2.6v, instead of 0-1V).

I have measured this voltage directly ...
