The air/fuel ratio is not a 'standard' display on the Scangauge but, using the 'Xgauge' facility, it should be possible to display A/F by inputing a code available on the Scangauge website. I've done this but no reading appears! I've tried 3 different codes so far but no joy.
Has any user of the Scangauge had any success in this? My PSI3 displayed A/F and it's one readout that I would like to have available.
