From that graph, it appears that Bank-A is the bad one, however the Nanocom recording you share indicates Bank-B is not swinging through the correct range. This why we suggested swapping them over & cleaning the connector contacts.
They should...
The O2 sensor data looks wrong. They should be switching at similar rates, so maybe it's time to put new ones in ? All the other charts appear ok to me, but it's dificult to tell from the pictures.
As I said before it's generally not...
Nanocom also shows BECM inputs including the window switches. That together with the ability to activate outputs to test the windows & locks means you can nail down where the fault is.
Not usually. Two Cats feed a single centre box, that then splits to two rear boxes. But saying that my MOT guy did find differences in the two tailpipe emissions !! Even he agreed it didn't make sense.
GEMS definitely has separate trims for each bank. Don't know about Thor. The pics above do show trim values, but the recording Pete12345 sent shows zeros ?? Also Nanocom is labelling them as Downstream when it should show Upstream Trims...
None of those show the O2 sensors. As said several times now, emissions depend on O2 Sensors, MAF, Engine speed & Temp, plus Air Leaks and how the trims are behaving.
Not got one, but from various forums it appears Thor are much more...
Another thing to try is to use Nanocom Instrument Mode for recordings. Select Instruments & Motronic.
Make sure Auto Recording is OFF. Then start the car & enable recording.
Here's an example of the recording from one or my P38's. This...
Well that data shows essentially the same as post #30 above. Both O2 sensors are switching, although Bank-B voltage range is lower than Bank-A. My understanding is this shows the air-fuel ratios are adjusting more on Bank-A, but not sure...
Rather than uploading lots of duplicate pictures that don't show dynamic values, just upload the recording file from Nanocom. Make sure you do the recording at Idle & 2500rpm.
Before you upload, change the filename from "xxxxx.csv" to...
Unless you have O2 sensors after the CAT's (i.e. 2 pre & 2 post), don't bother with the Downstream values. Main focus should be these values:
Upstream Bank-A & Bank-B
Short term trims
Long term trims
MAF
Throttle & RPM
Is the ECU in...
Definitely P38 and 2001
I started to doubt the pressure gauges but I went to the guy and checked, everything is correct. This explains why the pump had to be repaired so often. In the end, I put a non-original ring on the pump, which I took from...
+1 on the compressor limit. Even with a gauge directly on the pump outlet, I've never seen more than 190psi. Hence why I asked if it was definitely a P38.
Every time I've tested... maybe on 3 different green pressure valves, they've stopped the compressor at 150psi on the dot.
I'd have thought the compressor itself would have given up the ghost by 200psi!
I don't know how accurate my pressure...
