G1 V5 NB Oxy calibration

Recommended Posts

Hi - I'm using a Link G1 V5 without the secondary four pin header. I'd like to read in the analogue output from my AEM X-Series wideband to the G1 NB Oxy input for datalogging.

The X-Series does not have a simulated narrowband output, so I'm planning to use an Arduino to convert the signal from 0-5V to 1-0V. I have the voltage/AFR calibration curve for the AEM WB output. Would you be able to provide sample points (or even better a transfer function equation) for the preset G1 NB Oxy voltage/AFR curve?

Cheers.

For the narrowband input I dont think there ever was a conversion to AFR or transfer function, as far as I remember it is just logged/displayed raw voltage.  Curious why you dont have the WB input, was this an older G1 that was upgraded to V5?

Ah I see, thanks. You're right my ECU must have been an upgrade to V5. Do you know if the NB Oxy input will be clipped to 1V Max, or should I be able to use it to log the 0-5V WB signal as raw voltage anyway?
