    Hello and thanks again for the link.New pipe is in .Problem is still there , no power on hills. I thought I would take the liberty of sending my data output from a friends FOXELL NT301 .Its not a Hawkeye, but its the best I could lay my hands on for now . Also, the MAF reading is in g/s and NOT mg/s. Please have a look at my data and see if you can spot any irregularities.

    methinks more info is needed ..
    e.g. did not spot fuel pressure data in the .pdf
    [ might have missed it due to the length
    [ i more or less did a quik scan thru

    have you got the pierburg lp.fuel pump yet ????
    `````````````````````
    ideally the following data would be useful :
    pressure from the lp.fuel pump
    high pressure in the fuel rail
    voltage on the rail fuel sensor
    voltage data from the hp.fuel regulator

    any idea what this is referring to ?
    "re(kPa)102.0"
    it's repeated a few times
    it's a pressure measurement .. but which ?

    as for turbo boost .. or m.a.p.
    that will also be related to the amount of fuel injected
    i.e. not much fuel = not much exhaust gas to drive the turbo

    You need to get a diagnostic reader that you can understand.
    The low pressure fuel pump needs to supply over 300, preferably over 350kpa.
    The high pressure fuel rail should be around 25,000kpa at idle.
    Boost pressure (MAP) should be around 100kpa at idle.

    Hello, all, so yes, new pierburg LP pump. No difference .Then ,I unplugged the LP fuel sensor (see pic ) .Landy takes off , revs go past 3000 rpm, all the way up to 7/8000 rpm ,she flies for 100 m , then engine cuts out. Can you please confirm the picture is in fat the LP fuel sensor and if so ,where is the best place to buy or can you send me the part numner so I can google. Thanks in advance. It was a great feeling to have her FULL POWER back , even although it was for a short while. Im so relieved its not the Turbo veins that are stuck open or am I being too presumptous as yet ?

    Are you sure? :eek:

    A diesel won't rev above 5300 RPM. ;)

    something's very wrong there

    op.. are you sure it's a td4 diesel ?
    afaik the m47/td4 redlines at 4800rpm
    personaly i keep mine under 3000 [ has larger than stock tyres 2700=70mph ]

    reving a diesel up to 7/8000 rpm be asking for big trouble sooner or later

    ```````````````````````````````````````````````````````````````````````````````````````````````````````
    just my opinion .. feel free to differ. ;-]
