Here's an update:
While in the garage, the car wouldn't start, alarm probs etc.
They have identified it down to a fault in the 'ignition relay' under the passenger seat, part number 965 618 130 00. Apparently, it affects the fuelling as well?
Now more bad news: it costs £480!
And it get worse: no-one has it in stock in UK, so have to order from Germany. Another week...
... and then he can look at the tuning...

No real progress!!!!!!!!!!
The car is starting at least (it was not the control unit after all, but an electrical fault)...
My guy just phoned me after another week. He has set it as I asked (ie. 3% CO, lamda disconnected and the car is still 'over-fuelling'!!
He is telephoning Stephen at imagine for some help....

Drew, are you serious?
How can we get more boost?! Its been tested at 0.8 (as recommended by Kevin & Stephen) and 1 bar. It has the HFS!!!
My feeling is there is a leak/ blockage or electrical short going on....

I stood and watched him dyno my car some time ago, the main reason was to get afr's on some kind of chart so i could see where i was at, i was dissapointed that he doesn't have the facility to do this as i was under the impression that he did, he just said it was plenty rich enough which wasn't really the answer i was looking for.
He seams like a really genuine bloke though, i think he's more geared up for Motec and spent most of the time trying to convince me to do the conversion. You won't get any luck going to Weltmiester as they won't do any tuning on anything older that a 993 unless it's an RS, they will dyno it for you and they do have the facility to give you a chart showing your afr's across the rev range, as do GForce, i'm not sure about Fernsport but i think they will have the same policy as Weltmiester, maybe GForce might be able to follow instructions, i'm not very knowladgeable on the technical stuff but what Nathan has just said makes perfect sense, if everything else is exactly as it should be then it's got to be the WUR, 9m had mine set for a bit more fuel at WOT by the company that rebuilt it and the car ran like crap, they ended up just getting it rebuilt to standard spec and it was fine, the slightest adjustment makes a big difference apparently, it might be worth getting him to call Brian to talk him through setting the WUR up properly, even then though he simply doesn't have the set up to get you a nice flat 12.0-12.5 afr anyway so you're a bit snookerd, my car still runs pig rich but i've learned to live with it

Thanks guys.
We have tried 2 WUR's, Brian's adjustable, and now back to the standard one. F*** knows how he has set it though. he has left me vmail today, we'll see...

Well, there is one possibility which I thought of but forgot to type on here & that is the ignition timing.
I know that you had a new flywheel fitted. Now, I am guessing here as I don't have a 964t, but does your car have a crank sensor? I am thinking it does as you guys were talking about that modded bracket which advanced your timing 5degrees or so.
I wonder if the sensor is not working properly due to the new flywheel. Did you get it from Patrick Motorsports in the USA, I hear on here that they make mistakes sometimes...
Has he checked the sensor signal with an oscilloscope or maybe even just a timing light (that is what I would do first as I have never even seen a real oscilloscope ).
I see you can buy USB scopes on ebay for about £100.00.

I doubt its the flywheel. Patrick went into great detail with the spec. and balancing. I am sure they have things very well sorted. Besides it would affect the idle, which was not the problem.
The shop called me today and say that the road testing went very well and I am expecting my car back by the weekend....

Mark is saying when the car is just ticking over.
Glad to see you are making some progress and I hope it will all be sorted out very soon. Weltmeister do not exist anymore, Fearnsport look after quite a few 964RS's and ran the one that won its class in the britcar 24 hour.
He does not have a dyno but must have access to one I imagine. I think a lot of the problem is that Bob like many others is old school 911, technology has moved on a lot since then and they are just not up to speed.
