UTCIS feedback - Anyone use this instead of the standard WUR?
 

Is there an advantage to this over pushing the pin up and down on the standard part?

Looks very interesting. Anybody have any experience with these?

These look interesting, but there is no information that I could see on cost, which is pretty critical.

Knocking the plug up or down manually is pretty inaccurate.

Best of all, it seems to me, is just making the WUR adjustable, like this:

The price is listed on the Pelican link, $634.25, plus another ~$34 for fuel lines and an adapter.

As to making the WUR adjustable, the adjustment described in that thread only effects cold control pressure. Once the bimetal strip is hot, it is no longer in contact with the springs, and has no effect on hot pressures. John Walker posted a thread on an internal adjustment screw for the warm pressures.

I still like the adjustable fuel pressure regulator idea. You would lose the cold start enrichment, and the Acceleration and Full-Throttle Enrichment, but that isn't used on CIS-Lamda cars anyway. It would be a hell of a lot cheaper than $670.

Ouch! That's even steeper than a replacement WUR! Seems to me the idea behind this would be to reduce the cost of the factory replacement if you can't modify it yourself...

I agree it's too much money, I would give it a try if it were at least close to the WUR price.
