Prv arrived this morning.. Which pipe on the current ebv is the 'boost source' and which is the 'to actuator' ? I have one pipe with red dot and one with blue dot... ? Thanks the instructions provided with the prv are basic to say the least! Think it is written in engrish! ;-)

Red - boost
Blue - actuator

Thanks flea.

I guess I will use my boost gauge to calibrate the PRV to 1.2 BAR but how do I know if the Boost gauge is correct? It sits at -.1BAR when the engine is off... should this be at zero?

Is there a way of setting the PRV to the required pressure release prior to fitting to the car? I have a track pump that I use for my MTB... could I attach the boost pipe (RED)to this to set it to 1.2 BAR before i fit it? Maybe this would then save messing around with test runs on the road etc?

What do you think?

Thanks

to check if your boost gauge is reading right - rolling road it again and compare what your gauge is saying to what the printout says!

Kinda need a rolling road to do that though eh ;-)

Reckon i'll have to wait until the weekend to fit the prv.. Daylight has all but gone by the time i get home.. But i just connected my track pump to the boost side of it and by turning the knob in and out i was able to set it at pretty much spot on 1 bar.. I push the pump down hard and it releases at 1 bar pressure... Neat eh! Well it's a good starting point anyway ;-) least now once it's on i should only have to apply minor adjustment to get it to 1.2 bar ;-)

Just fitted prv.. With a bit of adjustment i got it to between 1.2 and 1.3 bar.. Took it for a run and it did seem to boost a bit quicker but on hard acceleration (i.e. More than quarter throttle) it did the same thing.. It accelerates like nobody's business then judders and continues to do so until i take my foot off the throttle slightly... Like fuel starvation? but if i feed the power slowly it will pull like a train all the way through the revs...So back to the drawing board eh! I put the standard ebv back on for now to be safe until i find the real problem.. going have to get over to flea soon.. :-( so frustrating!

I'll continue this tread in 'Technical Issues - intermittent power loss' Emerson
