60840, Wideband o2 sensor reading, what should it read?
Posted by TXTurboGS, Nov-17-03 03:49 PM
Hi. I just recently bought an FJO wideband o2 sensor along with the datalogger and LED display. This is a newbie question for real, which I am. What numbers should I expect to see on the display while at full boost (15psi) or at idle.

The higher the number, the richer the mixture right? It reads particles of air per particles of fuel, or I'm I wrong? SO I assume the higher the number, the leaner. Thanks for any help. :cheers

higher the number the leaner you are.

at idle or cruise.. you should be around 14.3 to 14.6 in my opinion.

under wot at 19lbs of boost i sit at 11.1

even 11.1 is a tad rich.

Turbo 420a's will make the most power at arounbd 11.2-11.5:1 AF under maximum boost.

At idle or under closed loop ecu conditions, expect to see nearly 15:1.
