So I removed the vanos yet again to try and find a gremlin that has been haunting me. Everything checks out except for the Timing. Seems that following the Beisan procedure after all isn't correct.
The car is now error free and seems to pull better, with one problem though. It started pinging and is more noticeable when on operating temperature. This leads me to believe the car is in fact running healthier but also hotter causing pre ignition. Combined with the fact that it's still on OEM DCPR8 NGKR plugs doesn't help.
I'm going to get DCPR9 plugs asap and if that doesn't cure it, add even more octane. I'm pretty sure that will cure it, if not we will modify the map to pull ignition timing.
When this is fixed a rerun with the C63 and K04 GTI is in order :rollsmile:

Andy, you may have seen it but here is the BMW TIS for timing.. I don't know much about the detail, but you can compare for your own info...

Thanks for the input guys :thumbs:
Niks, they are copper core at the end of the day. Merely the tip that is coated. Standard gap is 0.8 and I will set them to 0.6mm as the boosted S54 guys are doing in the states and EU. Will give some feedback once they are in and car is running.

Mini update
Not sure if i posted this before but I want to make a larger cooler reservoir for the charge cooler. Thats not happened yet but I have solved the compressor surge issue.
Removed the hks blow off valve (no more choo choo noises) and fitted another Kayser bypass valve in its place. So now the system has 2 of them. One on the discharge pipe and one further down on the intake manifold.
Seeing as the car stood for a month while I was otherwise engaged I assumed the fuel would have degraded a little bit. My reason being is that the car started pinging slightly again. NF sorted that out though
and I'll be driving the car for a bit now. It feels Mega compared to the NA ones.
It sounds NA now as well. Sleeper!

Could have been that the spring on the HKS was set up for Turbo and Not supercharger. You need a softer spring for supercharger because of the difference in PSI delivered between the two types of compressors. The softer spring will allow the BOV to release sooner whilst the turbo hard spring will hold more pressure. If your BOV had a turbo spring, which is most probably did, it would of been the cause for it not releasing fast enough and thus building too much pressure in the intake which in turn ends up sending the air back towards the compressor.
Very well documented problem on M3forum with guys trying different style of BOVs on their supercharged e46's. The TialQ50 which I had was known for being too loud, so guys installed harder springs to lower to volume of the choo choo, but then started getting compressor surge.
Anyway, glad you got it sorted.

Sleeper is always good Andy. The BOV on my car was way too loud and often scared off the competition
