    boost controller issues

    in New South Wales

    Posted

    You need a 'Mighty Vac'. Its like a hand pump with a gauge on it that you would connect to the actuator. You pump pressure (the intended boost pressure level) into the actuator and see if it holds on the gauge. If it drops down then this could be your problem. Not the sort of tool that everyone has laying round the garage unfortunately...

    boost controller issues

    If this problem occurs by fault of the boost controller setting it would normally point towards the gain (the speed at which the solenoid switches on and off to stabilise the boost level) being too low. If the boost was oscillating either side of your desired boost level at a very fast rate as opposed to a slow steady rate (easiest seen with an anologue boost gauge) then this points towards the gain being set too high. You need to find a happy medium with the gain control.

    If you are not able to get the boost curve flat with the gain contol then I would be checking the vacuum / boost hoses that run between your boost pressure source, solenoid and wastegate actuators. Have they all been replaced with new silicone hose? (good idea). Do they still have any factory fitted resrictors inside the hoses? (if so remove). If still using the factory hoses one may have a split in it that will only be visable when the hose expands under boost pressure. Make sure that the solenoid's mounting position is not too far away from the wastegate actuators and if all good then get your wastegate actuators vacuum tested to see if the diaphragms are holding the extra boost pressure that they are now seeing. (could be leaking with the extra pressure but still ok with the std boost pressure). Could also be a boost leak somewhere between your turbo and throttle body..

    See how you go...

    2 Blow off valves (turbosmart copy's)

    Don't mean to be ass but need to put in a breif blurb. The parts on these BOVs are not anodised so the valve (piston that looks very ordinary) will wear very quickly and eventually jam plus the spring has eight active coils whereas ours have 16, for a very good reason.

    Yes these are priced nice and cheap (love to know where the hell they come from) but just wanted set the record strait - will not work exactly the same as a Turbosmart product.. Sorry...
