Wow I just finished reading it thanks for the link what an awful journey. Hows the car run now 9 years later?Quote:

I may have bought the undiagnosed reason for him giving up on his 3.5 V8 on 4cu with the though it would solve a problem one day for me in its current state. Interestingly the ECU is the one part the LR expert, I picked the car up from today, didn't substitute. They were nice guys and did a bunch of tests and threw in plenty of moneys worth of 2nd hand spare parts so I can't sh%t can them but I would have thought they would know how to diagnose this car with 2 hours of paid time not keep saying strange this happening or "fuel problems". If they were happy to take it in should they be able to fix this type of system? He told me on the phone last guy that brought one of the flappers in ended up putting a carby on his WTF That would have been very handy information at the time of booking because I could have hung up the phone. Mate, I'm no good at fixing them or I don't work on them would have helped too... I digress
What do you think I should do to this?

My ECU is the same as you picture, but the pictures I posted are of the opposite side. I removed both boards from the housing and inspected the circuit side rather than the component side.
What is the number on the ECU?
Keep all the components they swapped out, they are good trading items in the future.
If you can, have a electronics type fella have a look at the ECU and get it fixed properly. Nothing like "fixing" something only for it to fail 1000kms later.

Tried to lead me down the new fuel pump path followed by the "swap the injector rail over for another one I have sitting here" routine. The dickhead hadn't found the unclipped CTS. $150 an hour but has no idea... He used a pull tie to regulate the fuel in line and though that was some king of achievement. WOW. He replaced the 4 day old spark plugs and the 2 week old rotor button. I said stop working on the car I am coming to get it. I am assuming this bloke is retarded because he couldn't follow the land rover dealer training manual to diagnose the problem and just started swapping parts for $150 an hour. WOW. Land Rover expert... He said the last bloke that came in one of these swapped it out for a carby, no ****. I wish he told me that a week earlier because he can't fix 4CU but won't tell you until hes picked your pocket. Don't get me wrong super nice guy but either can't lay straight in bed or just a **** mechanic.
You've tip saved my arse, thank you so much. I got the rebuilt ECU back from injectronics this week. Injector banks were out of control over-fueling, they gave me the VASS test to prove it. Plugged it in this morning and dialed in the AFM and reset the timing and idle a few times. Car is now running better than ever!!!
That's good news!
Pity about the fella you took it to, these things are just set to try us.
I'd be keen to learn more about the place you sent it to, location and pricing, etc. Can PM if you want.
Well again, good news and you can get back to Range Rovering!
Seems I'm having the same problems. Will start up but have to keep pumping the throttle to keep running before it just dies. Unplug the AFM and it runs fine, no black smoke and ticks over fine. Plug the AFM back in and it stops. Anyone got a spare ECU that I can try ? How do I test the AFM, what should the voltages be? Cheers...
Can you leave the Flapper plugged in and remove the fuel pump fuse and see if it does it? Just want to isolate weather it's the fuel pump component of the flapper that is having this effect or the flapper itself.
I can't ad it, but if you search 'Lucas 4cu testing', there is a pdf from a GoMoG that will give you all the testing info and procedures you need.
