Tuning w/ an adjustable WUR

I've got one of Brian Leask's Adjustable Warm up regulators. Though I probably know enough about the WUR to do an ok job tuning it myself, I would love to find an expert. Anyone know a CIS-man who can help me tune this thing with precision? I live in Rhinebeck, NY, 90 miles from NYC.

Thanks.

This may sound trite -
But I have one of his devices myself and the exceptionally well written instructions are all you need.

I suggest you read them and re-read them - easy reading yet full of information, but you need to absorb the information so it makes sense as a whole.

You will absolutely need a way to measure AFRs.
Truly, that is all you need.

Leask

I bought a LEASK unit recently and agree entirely with Craig 930 RS.

As stated above by Craig and EP, you absolutely need an AFR gauge to tune it. It is pretty simple, if somewhat a PITA to get at (although it maybe more accessible on a 930?)

Guys Guys Guys,
Just answer the question here! I know a little bit about Doug's problems he is sorting out. If Doug, doesn't mind, I'll re-state his question.

He has a drivability/tuning issue on a vehicle he just recently bought and then made modifications to. His WUR may be set perfect, it's that he has some starting and running issues he needs diagnosed and it needs to be looked at by someone who will not "GASP" at the sight of an adjustable WUR throw up their hands and say I don't understand that thing.

So he's looking for a decent wrench close to him that can sort his motor out, and the motor has an adjustable WUR, for which setup on it should be confirmed.

I'm thinkin' there has got to be somebody who knows what they are doing around NYC? I can only help him so much from Florida, or I'd drop by...

You'll need to remove the WUR for the adjustment on the bottom, FWTW (to remove: 2 screws)

Doug's question stated he needed help with tuning an adjustable WUR, nothing else.
Sounds also possibly the idle adjustment / vaccuum leaks / other circuitry needs to be addressed.

Yep, send in an expert - hey, I have an idea - contact your local Porsche Club via their website/contacts and speak to people who can fulfill this need.

Not if you make a bracket and move it where you can get to the bottom.

Call Rik @ 854-928-6683 http://cimmotorsports.net/ he adjusted my car after I first installed the Adj. WUR and then readjusted after I added the solenoid, AFR gauge and zork tube. His shop is Central Valley NY about a 2 miles from exit 16 on the NY Thruway.

Yes,
That's why I expanded on it a little for clarification.

Thanks. I'll call him.

Fortunately, I now have an AFR gauge made by PLX set in my tach by www.inyourfacegauges.com. Brian's directions seem very thorough but like Les said, unless the car is free of vac leaks, timing issues, etc. adjusting the WUR is pointless. I don't want to begin adjusting it prematurely, thus I need a pro to check the vitals before getting into the nitty gritty.

Thanks for the help. I certainly welcome more suggestions.

You need the CIS gauges such as those sold by JC Whitney to confirm cold starting pressures of the WUR if you wanted to do this yourself.

A good way to find air leaks is to pressure the intake assy (thanks to Goran). Stephen Kaspar has also suggested using Propane on a running engine.
