Okay so I'm new to this what is a wideband? I have the dual aeroforce gauges I installed about a couple months ago. I still don't know what I'm looking for besides KR. I've heard about and read about the long term and short term fuel trim I monitor them I'm not really sure how to read them they fluctuate. Zzp told me to monitor air to fuel ratio they said should run in the low to mid 900's. I was assuming that's at wot? At wot I'm at about 920 with 0 KR they said it's good. I was wondering other opinions and I'd like to actually understand it better well how to read it anyways. Does the aeroforce gauge store data?
