guys,
I think I need some explanation on the o2 readings from the torque app via the obd2 connector (elmxxx).
On idling the values are the following
Intake 5.1psi
MAF 3.2g/s
Revs: 845
Load: 2.4%
o2s1Eq: 1.0
Timing Advance: 14.0
Throttle 10.2%
What I'm curious about is
- the throttle opening seems right?
- although the equivalence ratio seems to be right, but the voltage on the parameter: o2 volts bank 1 sensor 2 : swings from 0.1 to 0.8 but not in any periodic matter... most of the time it sitswell below 0.5.
- AFR ratio on idling is 14.6, but while driving it goes up to 22 and down to 10 or less..
- regarding the 02 sensor settings in torque app in the Test Results section, I couldn't get ANY reading to give a nice sinus! Basically only that could come close to it would be the O2 1x2. Anything other than that is just not right, but even values from this parameters are definitely nowhere near the sinus graph Isn't the 02 1x2 the post cat sensor ? shouldn't that be steady? Is the catalyst ok ?
I've uploaded some values from the short trip I've made (the engine was warmed up before the trip).
What I need would be someone to have a look at the data (will do another trip with more settings and could send it) and explain if there is anything ok.
I have a multimeter, how could I test the sensors (both the front and rear) with it? Where should the probes go and what should be the values ?
Cheers,
M
