I don't understand why there would be confusion but...this might help you (written for the AAN but should have some info that applies to your engine):
RS2'd 93 UrS4 5 spd sedan
94 UrS4 V8 6 spd manual avant -
Just wounder..
Looked in Vag-com and with the engine at idle I have 7,9% TB angle, is this right ? Shouldnt it be at 0% at idle and with the engine off ??
At WOT I have 99,9% TB Angle..Comment
-
Yes, this is OK.
It is also not percentage, but degrees.Comment

awesome!
Stil havin major problems with the car at low speed and cruising.. It stumbles and when I press down the clutch the rpm drops and bounces upp and then down and the engine dies :/
I have no leaks what so ever, pressurised it to 2bar..
Is there any way of diagnose the MAF in vag-com ??Comment
-
Do you get loud bangs out of the exhaust when this happens?Comment
-
Nope.. the only thing is small, small missfires at idle, 2-3secs intervalls..
the sparks look all great... the afr is at 14,7 at idle, around 11 at full boost (1,7bar) with 630cc inj.
Theese symtoms just happens at crusing without any boost or anything, att WOT nothing strange happens at all.Comment
-
Disregard that, I misread.
You probably have a boost/vacuum leak, pressurize the intake.Comment
-
No boost leak at all, pressure tested everything to 2bar.. the problems doesn´t happen with boost, only at vakuum, when I´m crusing..
The only thing I can imagine is a vakuum leak but I have -7bar at idle on my external boost gauge and 0,7bar in the instrument cluster..
The car idles fine at 960RPM..Comment

And this used to work fine before?
Btw, write a complete list of what's on your car.
If it has 630cc dekas it's not stock.
Also who tuned your car? Has it ever worked after tuning? What cams are you using?
Disconnect O2 sensor and see if the problem goes away.Comment

Stock head(stock cams) and stock bottom (AAN)
1,8t ignition coils
gt35rr bb
deka 630cc
rs2 maf with bigger housing
rs2 fpr 3,8bar
rs2 ecu mapped by turbo center in stockholm (450hp)
rs2 str exhaust manifold
3" downpipe and 3" straight exhaust
forge valve
front mounted ic with 2,5" piping
new gaskets everywere including injector bungs
new multitemp sensor and ecu temp sensor
camshaft sensor in a modified disty driven by the camshaft
Stil stock fuel pump since the car ain´t finished yet, new arrives next weak!
everything comes from a rs2, just bolted it up on my car!
Haven´t checked the o2 sensor but the sensor has only like 1000km on it..
works as it chould, no faul codes and has good response when meaturing it!Last edited by Carfreak; 9 May 2012, 15:30.Comment

But all the parts are mapped in a rs2 before I bought everything.. and the problems just accoure when cruising around without boost..
I still think it´s the tps, I will the tps tonight and take the car out for a spin and see! Hopefully I get a fault code if something is wrong!Comment

I know for a fact the TPS has nothing to do with it.
I also know for a fact that it's most likely mapped like sh*t if it only makes 450hp with a GT35R.
I also happen to know exactly what happens to transient fuel calculations inside the ECU when you stick a big housing onto the MAF and don't recalibrate the MAF maps.
Let's just say - either install a standalone ECU (Nira seems to be popular in sweden) and get it tuned by a professional or fly me over and have me map it on Motronic properly.
Or you can continue playing games with swapping chips from other cars that have little to do with your intake geometry and setup. Best case you'll never get anywhere, worst case you'll blow the thing up.
That's all I will say on this topic.Comment
