Went to check the stock SC and 930 WUR pressures only I can't find my gauge now!!

So whilst I was there I finished off a new oil feed to the main oil tank.
I've made a pipe that goes down into the main refill neck and also has a small air filter as a breather.
So far so good. it seems to work OK. I'll get some images soon and post them.

As for the WUR issue.
I plugged in the 930 WUR and it started, although it did'nt seem to go through the warm up cycle and the AFR at idle was 14.4 even after several minutes. When I revved the car a little the AFR went into the 18's so I turned it off and plugged the SC WUR back in.

With the oil return issues hopefully fixed I went for a drive and very gradually pushed further into the rev range.
The AFR stayed at mid to high 14's as the turbo spooled, then just as you can feel the power come in the AFR dropped into the 9's and power instantly dropped away and the car hesitates.
I'm assuming the issue is the WUR over fuelling as other threads say turbo AFR on boost should be between 11 and 12 AFR.

So the SC WUR does seem to be reading the extra air flow and trying to compensate with extra fuel but if the AFR reading to correct, to much fuel.

Is far as I know the only read adjustment I have is the the 3mm hex fuel head screw. I've read this adjusts the idle and the midrange some.
My current warm idle is 12 AFR and cruise is AFR 14

I'll have a go at leaning it out with the 3mm hex and see what happens. Hopefully it will lean out the on boost also.


If anyone has any idea's I love to hear them
