84 turbo, federalize with a unknown WUR

Car came to me not running for last 3 years.
It did run but got less dependable before parking it.
Aftermarket CD box with prematune innards and matching coil, but not a 001,
I jumped both relays to get the pumps running but non start.
Removed the jumpers on the relays and got the 5 second burn off with some ignition afterward.
So, too much fuel in the system.
Possibly the fuel distributor pin is frozen in the up position.
OR the WUR, which I have never seen the likes of, is the problem
Can I get help with the identifying and possibly how it works, pictures below
Help and Imput is appreciated, thank you
Bruce

Some sort of electronic wur it looks like? Where does that plug go?

Looks like one of the UT Digi WURs? That may be your problem. Suggest you swap the WUR out.You won't get much help from UT.

what are the fuel pressures?

did it flood the engine?

is there a vacuum hose from the control box to the TB?

I think I would dump it and get a regular WUR

A quick search on the UT gizmo will give insight into that silver box. There was a thread some time back that chronicled all the difficulties they were having. Quick fix as others have stated is to swap it out for a standard WUR. You may need to adjust the mixture if it has been manipulated to work with the UT unit. If still dumping fuel then look at the FD.

You cannot tweek the Digi WUR settings without a download programme from UT. You hook your laptop into the black box (There should be a USB connection coming from it.) It also has to splice into the purple/black TD wire for rpm. It looks like a Gen 2 unit. They used a fuel injector duty cycle tweek to control the WUR control pressure. The injector was doing the same job as the diaphragm in the regular WUR. Tweek the duty cycle and you altered the fuel pressure on top of the FD piston. The injector controlled the flow back to the fuel tank. But as far as I know they never worked properly. Mine didn't. Dump it or you will be spending a huge amount of time chasing shadows. Everything should retro fit back to a regular WUR. You will have a spare TD wire to dispose of.
Regards
Alan

I ve been on the search for the proper WUR, got 3 numbers that work and a lead to one.
As I was thinking, replace after imput.
Thanks,
Bruce

WUR for a Euro 1984 930 would end in -112.

i cant keep the numbers straight, but get the USA one, it is a better one to make adjustable.

All can be made adjustable except the early 3.0L 930 units. I run a modified -112 WUR on my 1985 Euro 930. Most commonly found (in the US) is the USA -153. It makes no difference what the part number is once the modification is complete because you can then put the settings wherever you want them (which is both good and bad). We also have made 930 WURs out of 911 WURs, fully adjustable. All you need is the correct housing.

the 054 is the bad one. I cant adjust boost or threshold settings.
I would like to drop my boost about .2 bar.
mine has one adjustment in the bottom and it adjusts the WCP and boost pressure together and one adjustment for CCP.

brian I got this WUR form you. if it can be made to adjust boost separately then we need to talk.

There are 2 versions of the -054, early and late. The early version lacks the ability to adjust threshold, both versions can adjust boost. Yes glad to help if the unit isn't working correctly.
