Flat spot at 5200rpm on 2.0T - Does yours do it?

[GTIjames]

i have been using the revo guide and playing with the settings.
 
i was getting the hesitation with T6 too, its only when I reduced the settings to T5 that the hesitation stopped and it would pull all the way to red line.

i am pleased with how its running now on B8T5F7

Have you guys tried leaning out the fuel to lower the request on the in-tank pump?

Is this a feeling that when the rev counter goes over 5k it feels like the turbo is running out of steam and then as you approached close to 6k it power comes on full again? I have studied my vRS with a KO4 fitted and i have noticed that it does this ever so slightly in 4th gear only going up an incline, not enough to bother me to be honest. It's obvious the ECU is seeing something it doesn't like and pulling back, maybe a sensor seeing high temps?

Its not the ecu pulling back imo, mine does it now even stock. It will only do it in 4th gear whilst coming from WOT at 3rd. Low revs in 4ths and then going WOT will allow it to pull without hesitation, but then the hesitation will return in 5th if you carry on the WOT.

Trouble in getting it sorted is that to experience the flat spot in 4th you will be doing between 75-80mph.

Mine does it in every gear. Does not matter what boost, fuel and timing is set to. By the way, what does WOT mean.

WOT=wide open throttle

Hi guys quick question about this. when my car was in for its service it showed a cat efficiency fault. does anyone else car show this? as this is why Aps beleive it to be the cat on mine. milltek are currently making me a new downpipe so i will know in a few weeks if this was the problem or not.

Just spoke to someone who reckons this could be the fuel truss sensor in the inlet manifold.

do you mean thrust sensor as in MAP sensor. also what makes them think this??

Could be wrong Simon, but isn't the map sensor the one on the intercooler hose before the throttle body? I thought the one on the manifold was a air temp sensor...

tbh imnot sure micky

Reduced my settings too and the flat spot disappear, and pretty happy with the performance also.

yes the car was at aps on friday again and the same fault code came up. they did an emmisions test and they were through the roof. so its 100% a problem with the cat. which he said would explain the flat spot at that time. its going in on saturday for a new downpipe and cat. so i will report back saturday afternoon if the problem has been sorted.

[chungster]

is the problem with the cat or the probe that checks its efficiency???
