Modulation is way out, should be 50% with the engine temperature at 95C. I have an easy way to adjust the modulation, PM me with an Email address if you would like the info.
Fuel flow out of range seems to crop up a lot. some say it's a worn FIP but I am not so sure. I have that fault on my project car, it has no effect on the cars performance. I will get to the bottom of the cause eventually.

The modulation is a must to set back to 50%

Fuel flow goes out of range when it shuts off and the control collar is moved to shut the duel off.
Note the comments above on modulation being read at idle with engine at normal (warmed up) temperature.
I'd be more interested in any faults in the ABS module. If it is a 4W TC model you can read the ECU values as long as you don't go faster than 5 kph (when the lights go out on the dash).
The more I think about it, I feel it MUST have something to do with the ABS module, since I believe it controls ALL the wheels.
As its one of the very last P38s made & DHSE model, I'm assuming it will have 4w TC ??
The way the lockup fades away after a short time suggests to me its pressure related.
Is there any way I can disable ABS/TC to try again & prove it?

Yes your year of car will have 4 wheel ABS. Unplug the ABS ECU and see what happens. Modulation info will be sent this evening when I'm in my office.
Lucky day, managed to source locally a set of 18" alloys from a guy just round the corner who was about to weigh them in!!
Can you believe, £50!!
Even luckier, managed to sell those awful 20" for a little less than I paid for the new tyres.
Even luckier still, I kept a brand new set of 18" alloys from a Tiguan I recently sold which had 20" originally, so the tyres went
straight on the RR!!
Woja fink??

I would be worried about the tyre ratings from the Tiguan, they may not be up to supporting the weight of a P38

Very nice. they are L322 alloys, presume they did not come with the spigots?
Interesting facelift also, first time I’ve seen that

Yes, I do have spigots, I had no choice about the wheels, that's what the guy had, however, of all the designs out there,
they are the best lookers in my opinion, I love the way the spokes end at the back of the rim, leaving a deep 'flange',
just my opinion of course.
The original grill had all the support ribs behind broken/missing, so I cut out the slats, keeping the original outer frame
& grafted on a chopped/altered unit from a RR Sport, it fits ok as its still using the correct frame!! ( I cheat a lot )

Do you think I can pull the relevant fuses & relay instead? The glovebox is back now & it was a cow to set it to work right.

As said before, corrosion in the ABS ECU connector or a duff ECU. They do fail from time to time. I don't know, but you can probably look at live data from the ABS ECU with Nanocom, that might show where the problem lies.
The ABS ECU was removed, wiring connectors again like new, all coated with Stabilant, as well as trying a replacement ECU.
If corrosion bad wiring bad or ECU duff, would not Nanocom flag up a fault??
Is it OK to drive with Nanocom connected?

Certain failure modes of ECU's will not flag a fault.
What is "Stabilant"
Yes you can drive with Nanocom connected, just don't start the engine with it connected, connect after starting.
