    About 1 bar above atmospheric pressure maximum with the engine under load. On my diagnostics, atmospheric pressure is shown as well as boost pressure, at idle the two figures will be much the same.

    No power and black smoke sounds like turbo pipe has come off or collapsing or intercooler blocked.

    New parts do not always work these days, needs diagnostics to check the MAP output.

    Belt, pullies and water pump if included the system. Peace of mind. I've got a mercs vianno here, a 3.0ltr diesel v6 at the garage with a destroyed belt wrapped up in the fan. An elastic belt to boot as well. All going to be changed as I've...

    It's normal the replace the idler pullies with the belt on many cars.

    This was frankly an incredible read. Thank you for making my flight go by in a heartbeat.

    Bit different in the UK & Europe. anything that could affect the vehicle has to be declared to the insurance and in some cases a check at a government test centre is required. Good luck with your project.

    I have a couple that definitely have issues with solder joints on the wires into the PCB, although that could be PCB track issues. Was planning to replace the capacitor at same time. Will try your heat trick (but not too much heat) !!

    On all the ones I have seen that have failed, it was just the big electrolytic, about an hour to replace. I wonder how your mods will affect the vehicle insurance as they have no type approval.

    We tried to dig out the potting on a valve driver and basically just decided its easier to design and build one from scratch.

    PCB is in the Pick and Place machine.

    A bit of heat on the back helped.

    Pure curiosity, I was wondering if the thing was working.

    Why are you worried about the degree of movement of the EGR valve? It's better to block the vacuum pipe so the EGR never opens and thus saves all the exhaust crap from being ingested by the engine. I run both mine like that. Just make sure that...

    I was unaware that the P38 EDC could report an EGR valve fault as there is no feedback to show if it operates. The fault, if there is one, can only be the solenoid that operates the EGR valve using vacuum. As brianp38dse said, pull the rubber...

    ok so you put a new battery on, then a new alternator. now, you need to fully charge the battery with a battery charger and try again. the smart alternator will eventually learn your new battery profile

    I think it will just adjust itself and work. You do have change the gearbox settings to use a different tune

    GEMS has a setting for 4.0 or 4.6, but cannot find anything in the Nanocom for Thor ?? Either the original Thor ECU might learn the new engine behaviour, or it will under/over fuel because the firmware is wrong !! Best talk to one of those ECU...

    They do a system like this for disco 3 and 4. 😎👍

    The sensors require a Gnd and 5V power supply input and then they have a 0-5v output on the third pin. So they dont work like a convertional pot where you can just invert the signal based on where you put the GND and 5v on the sensor. So the...

    Got PCB, all the components and the new sensors today.
