WBO
Wide band oxygen.
We have cj125 integration
TODO: document it better
We have a few rusEFI console commands relevant for cj125
cj125_info
cj125_restart
cj125_calibrate
AndreiKA says Prometheus works
Matthew says 0.3 SOIC-24 boards works
Wideband controller based on Bosch CJ125 chip
green is vUr, temperature feedback
red is duty cycle
yellow is vUa, the lambda current measurement
white is converted AFR
fully operating in <30 seconds
in to closed loop in ~18 seconds
P=30
I=5
D=0.3
though you could probably use D=0 since the system is already damped so hard
50Hz
With SOIC-24 rusEFI module W1=W10=0R means LSU 4.2
With SOIC-24 rusEFI module W1=W10=Do not populate means LSU 4.9
Q: Any troubleshooting hints when things do not work?
A: VM wire between CJ125 and sensor is virtual ground, should measure 2.5v when sensor is disconnected.
