We have made an enhancement so that old threads should now link from search results to the correct thread. This is not yet in place for single post links
If you managed to snap it, then it was probably old and brittle...
Btw, I need to send you a chip with logging enabled and you need to start making logs with ZT2+Vag-com cable.
That way we'll see remotely what's going on
Yeah it was a couple of years ago i replaced it because i suspected it wasn't working correctly anyway, i shall get another though to test the one i do have.
I have a serial/usb connection directly out of the zt2, i haven't hooked it up to my laptop or installed the software yet, i've just been using the LCD screen. I have egt, wb o2 and pressure hooked into it in a self-contained system, i haven't hooked anything else like tps or rpm into it as i didn't want to splice into the stock loom without knowing what i was doing. Also it is not emulating nb o2 to the ecu, i've left the stock lambda in there.
But yes, by all means send me something to hook into it and i'll link up zt2, vagcom or whatever we need to log some data.
Not measured fuel pressure, how would i do that? I intend to try another fpr if that's what you're thinking?
I like the idea of hooking up to the rings in the fusebox, but then you have to go through the hassle of getting the wires back into the car behind the dash... not confident enough to splice into the ECU wires though!
The pressure has to push the piston up with the help of the underpressureline. In the pic, the pressure line is attached to the side of the Valve. This is wrong.
In this pic the Forge is in the wrong way:

In stock form yes, but at higher pressures this can push the valve open, as the vacuum hose does not flow enough.

There is only really a right and wrong way for the stock valve, on aftermarket you can run them in reverse to stop the increased boost pressure pressing open the piston and also some cars seem to run better with them in reverse.
A stiffer spring would also help in some case.
i'm not a fan of forge valves, they suffer from air leaks quite a lot especially the ones which are screwed together.
Having tried them both ways around, the orientation of the valve in the picture works better. I remember speaking to Forge some time ago about this and I seem to remember that it doesn't really matter but you do get some odd behaviour with it the other way around (sir buff's way).
I removed a DV like this from nip's car, as it was leaking from tha casing and the first one I had leaked too, but this will show on a leak test. What won't show and I assume what prj is referring to on a few posts, is whether the DV is sealing against pressure or not, as this is not tested under a normal full system pressure test.

Souds like Andy needs to remove his DV and give oral pressure to the piston shaft then... might want to ask his missus for tips
Also to say - I think I'm running mine backwards, it holds 2.2bar fine in this configuration although you do get an interesting sound if you lift quickly with peak pressure - dont think its dumping quite quickly enough!
