JonR Posted September 26, 2018 Report Share Posted September 26, 2018 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.

Adamw Posted September 26, 2018 Report Share Posted September 26, 2018 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? Quote Link to comment Share on other sites More sharing options...
JonR Posted September 26, 2018 Author Report Share Posted September 26, 2018 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?

Simon Posted September 26, 2018 Report Share Posted September 26, 2018 It will be limited to 0-2.5V but is expecting a 0-1 volt signal Quote Link to comment Share on other sites More sharing options...
JonR Posted September 27, 2018 Author Report Share Posted September 27, 2018 Great, I can make that work. Cheers for your help guys. Quote Link to comment Share on other sites More sharing options...
