And also the part that Brian Leask has done a lot of work with...
...for the cost of a GTS WUR, why wouldn't you just pay Brian to modify your stock unit?

Indeed, and more to the point, why not get a digital solution?
As we're hashing this out, I'd like to point out one more major advantage the UTCIS has over any factory setup. This is actually the reason 930 guys are flocking to UTCIS. . .the factory WUR enriches too early, killing AFR and power between 3-4k. The UTCIS eliminates this.

I agree, and I've purchased one already that will be making it into club sport project (mostly likely...if not, then the 941). The only thing I can think of is the pure financial aspect:
<$300 = OEM-spec rebuilt WUR
<$400 = Brian Leask adjustable WUR
$700 = UTCIS-PT

I have the opposite, the wur enriches at high rpm, a great amount to. Good for security but not so good for power. I really hope you get the utcis running as planned, i´ve been thinking about it for some time. Seems like a good way to both be able to tune the AFR and keep the CIS which has been extremely reliable on both my cars. Thats seems not so easy to get on the different efi systems out there.

1+ on the high end enrichment
1+ on the reliability of CIS
i've turned up the boost and as a safety measure i've also dialed some more gas to be put in....just to prevent detonation..but at higher RPM and WOT i get black smoke and 3 pistons firing instead of 4  ofcourse because of the bath of gas that's being put in by the WUR.
i'm also waiting for that UTCIS to become cheaper...i've exchanged some emails with the guys making it...but as much as i'd want one right now..its just too expensive.

The thing that scared me away from the UTCIS was the question of reliability. Which appears not to have been answered yet. Having said that if it works as advertised, being able to precisely tune CIS is an undeniably huge upgrade.

One more thing to add to Dan's formula above. . .the Leask unit doesn't address the "premature" enrichment present with the factory WUR (3-4,000 RPM) unless you buy an additional expensive component for $269.

I've no idea were you got that impression. Daily drove mine until I seized a lifter. Once I repair that, I will daily drive it again. My buddy daily drives his efi converted vehicle also. Started everytime I turned the key.

D'OH, I know he lured you into it Min, but I respectfully ask that we keep on topic in this thread. . .it's a sticky, and hopefully it's eventually a reference point for UTCIS users.

I fired up the new engine and it does run ok.
But the UTCIS sensors seems to be way off.
Tempsensor is reading 10 celsius all the time (ambient is 20).
RPM is set at 1000 when the engine is off, add is approximately adding 500-1500rpms to the actual value. It is connected to (-)15 on the coil.
The pressure sensor is reading 0,2bar when engine is off and 0,45 at idle. Does that make sense?
The start-up map was loaded by UnwiredTools and is called AAAAAAA something.
The controlpressure is fine and according to the map. Did try to upload a new map and reset the sensors, but without success.
Running version 2.2.011 bought June 2009

dont take the RPM signal from the coil...you get spikes and errors from that place...use the DITC wire instead.

Well, that would be nice, if you had DITC  Neither Shaggy nor the 941 have DITC...

Old unit is off the car, and I am currently waiting for the replacement unit to arrive, hopefully soon! When it gets here, it will be installed and tested. . .stay tuned.
An interesting aside, as the product is under constant development, I am receiving the latest and greatest. Features in include modular cabling (separate plug-ins to each component for ease of installation - a no-brainer) and separate sensor box and computer box. The latter new feature should allow installation of the computer into the passenger compartment (a far better arrangement, IMO), while leaving the sensor box and its high pressure fuel line safely in the engine bay.
Fingers crossed, results hopefully soon. Where is that damn UPS truck?
