pre-heat wb02 stall
#1 · September 13, 2019, 4:23 pm
Found a setting "pre-heat wbO2 stall=false". Am I correct to assume that this means the it delays activation of the oxygen sensor heater circuit until after a set period of time?
If so, I believe I should set this to True. Everything I read says that if the O2 heater circuit is on, and you start the vehicle, condensation or cold fuel in the exhaust may 'shock' the heater/sensor and cause failure.
Thoughts?

I also have this question. I recently had a code 134 (wide band temp low) and wonder if it should be turned on? OEM's use this function. I do not see any explanation in the fitech definitions file.
