    sounds like you have an air leak, look at the front of the head on the right hand side, there is an air port there for the air shroud on the injectors. This should connect to the intake pipe between the MAF and throttle body.

    Who made the loom?

    To be able to see what is going on from a far, you really need to post a dyno chart that has fueling data on it, and know if the power is at the crank or at the wheels.

    What size turbine housing is on the turbo?
  5. UnitedMotorsport
    0.9% is the CO content of a VR6 with out a cat. A VR6 with a working cat will read 0-0.3%. Either your car is massively over fueling, or the cat isnt working. If your car falls before the required cat test date, then the tester was correct to use the none cat test.
  6. UnitedMotorsport
    Your cat is not working. Your car passed and your questioning it?
  7. UnitedMotorsport
    Use the 12v water housing Gethin.

    No anti surge machining.

    A waste gate is used to control boost, by controlling the amount of exhaust gas the flows around the turbine of the turbo. A dump/blow off valve is used to decrease the pressure in the pipe work between the turbo compressor and the throttle plate, when the throttle plate is closing. This is to stop the turbo from stalling.
  11. UnitedMotorsport
    There is no vacuum at the turbo.... FPR should take its air pressure reference from the inlet manifold.

    You will need to keep this or fuel trims will never set in the ECU.

    Why do you want to lock the variable cam timing into position?
  14. UnitedMotorsport
    There is no swirl pot between the 2 pumps?

    1H0 972 695 - Plug body ~£3 000 979 131 - Wire - 2 needed ~£1 each Who ever asked for £70 for a diag port is clearing injecting something into their blood stream!!! The pic of inside the ECU shows a secure module not an ordinary chip, still need VAG COM data to see whats going on. If I had to guess I'd say you have fuel delivery problems.
  16. UnitedMotorsport
    You can not diagnose something like this with out OBD' date=' I suggest this is the next thing you do, guessing is a waste of time. How much is a rip off? These are 42lb @ 3 bar
  17. UnitedMotorsport
    Can you post a screen dump of the main engine screen in VAG COM? What injectors do you have? ie part number.

    Just so that you guys know. The 2.8 and 3.2 head has different injector fitments. 60lb injectors are a direct fit to the 2.8 with 12v injector plugs. 52lb injectors are a difrect fit to the 3.2, again the connectors need to be changed. The ECU calibration will need to be changed to cater for the injector size, for fuel and fuel consumption calculations. If your going FI, don't even bother with stock injectors, you are wasting your time. Don't listen to the myth of, "bigger injector use more fuel all the time." If the ECU calibration is correct, injector size doesn't matter. Fuel usage is dire

    What was the result of the compression test?
  21. UnitedMotorsport
    No its one or the other. C2 software is protected by encryption and can not be remapped by a 3rd party. Probably worth finding out which.
  22. UnitedMotorsport
    What software is in the ECU, C2 or stealth? It can't be both.
  23. UnitedMotorsport
    Sounds like at least one cylinder is low on compression too.
  24. UnitedMotorsport
    Me either They didn't. When the VR6 was 1st produced (OBD1) they were 4 bar and then when going to OBD2, they went down to 3 bar. Remember all Corrado VR6's were OBD1 from the factory. I can only think they did this to stay in line with the design/test characteristics of the injector they used, and also reducing stress on the fuel pump.
  25. UnitedMotorsport
    What is the part number of each of your ECU's?
