surely that would not work because the join is well before the centre box.

I might be in Reading next week, but don't know what day yet. If you're nearby I can bring my Nanocom.

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...

But that one didn't tell us to ignore it . . . hence we actually did ignore it.

Similar threads are available. Just to keep.it balanced.... https://www.landyzone.co.uk/land-rover/duplicate-please-delete.398546/

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...

I'm still ignoring 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...

BTW, re the thread title, what is "faked" ? or did you mean "failed"

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...

ok. Ignoring . . . .

Pressure test with engine hot & not running ?

Fixed it . . . .but your reply doesn't update

P39?

Yes after you guys pointed it out, I checked RAVE & it does vaguely show the correct orientation. Can I be bothered to remove & refit ?? Hmmm.

Look for “RAVE All Models” version. It’s got lots of Classic RR stuff

Definitely needs more investigation. You must be the only one with a P38 EAS pump that can produce that much pressure.

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...

Still got same job on wife's FL1, so will probably get polys for that !!

+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...

Yes they look reasonable to me. Voltage difference could either be differences in the sensor tolerances, or maybe slightly different supply voltage due to contact resistance in the connectors. You could try swapping the snsors over to see if...

Yes they are tight. Old bushes are about 49.85mm dia. The arms are about 49.7mm internal, but are about 0.25,, bigger on one side measured with my vernier. New bushes are 50.2mm even after freezing overnight. So heated the arm ends a bit &...

Not sure how 1992 differs from 1995, but here's the later diagram with pin & colour info:

Not sure what the valve block seals will handle, but if it really if getting that high, check the pressure relief valve. It should blow off above 180psi.

Absolutely correct. There are loads of electrical noise sources in cars, hence why the HK Audio uses balanced audio connections & have each amplifier grounded. Most likely that car has corroded connectors in the footwells . . . where the...
