hi guys i have programmed my SGII to display some extra gauges like AFR, absolute load, o2 sensor temp, o2 voltage, maf, etc...

my problem is with the A/F sensor. it is very boring to monitor because it seems to be always at 14.5-14.7 range. unless i climb past 3.5k rpm at wot i don't see much difference. at 6k rpm in wot i have seen it hit 10.9. otherwise its fairly static including wot at 2500rpm in overdrive gear. you guys with wideband sensors, is this correct? is your afr always at 14s unless your operating at high engine speeds no matter what?

thanks
Ali
