Some of you may know that my RR session was a bit of a no go due to low fuel pressure after about 3k rpm.
Just took it out to the local relief road and ran it through 2nd 3rd and 4th from 2k up to the limiter.
The problems are more prevelant in 3rd hgear. 4rd gear from low rpm you can't tell so much due to the transmission loss in that gear.
2rd it just feels a bit flat but in third from 3k upward it hesitates then you can feel it pickup somewhat then hesitates etc. Not a misfire though and not really drastically noticable.
4th gear is appauling doesn't seem to accelerate as well as it should.
Now could this be the fuel pressure regualtor? Fuel pump was tested and is running 3 bar constant.
After 3k rpm lamba is at closed loop, so relies solely on the fuel pressure regulator.
Anyone got an ideas?
