I have been using Mobil1 0w40 the last two track seasons, and I have only seen excellent blackstone results. See attached. It was after I believe 5 track days and some autocrosses.

But thanks for sharing. I'll have to compare it side by side with mine. Oil change planes for next weekend on the Miata and will do another analysis.

My 6ULs for the S2k shipped, at least the ones from JR. Haven't received shipping notification from the 949-ordered ones....
Next up for ordering is the SM damper and hood vents. I have a bunch of little stuff to deal with on the car, but have been out of town and busy and sick and unmotivated. But I drove the car a couple weekends ago and had a total blast -- love this thing.
Also, does anyone want a wrecked, low-mile, VR6 Eos with the DSG? .....
Also also, got the interlagos wheels installed on the wag. I luvs it. You can tell they're really heavy though, and it rubs a bit over big bumps, but love how it looks. Going to drop it just a wee bit with VW DriverGear springs and leave it like that til VW issues their fix and all that **** is done so I can do the tune and DPF delete.

Yeah. I want to be able to let VW do their fix on the car, THEN mod it. I don't want to mod it, then not be able to do the fix and remain compliant.
There's more and more rumors of buyback, though. Ugh, I hope not. I love this thing.

Getting rid of the oil cooler made oil pressures good. So thats good.
But other bad news.
Were getting weird misfires when upping the boost. Timing is also ridiculously retarded. @curly can you comment on this? I wasn't there for the dyno session.
Here are logs of wastegate and boost control turned on. It sounds almost like fuel cut, and you can see rpms drop.
Another issue is a VVT1 error. I'm not sure what this mean, but one thing I did find out was that by using VVT test mode I could adjust the VVT duty cycle. When the VVT duty cycle was > 43% the VVT error went away. Back to 40% output and it shows up again. There is a log of that too.
@Ben, @Braineack any pointers?

Just change your min so it doesn't error. Sounds stupid but that's what I've done with no issues so far.
Eds car was a little prone to spark blowout and ping. We were extra cautious at the dyno with spark.
I think he's on open loop boost. Is he hitting higher pressures with the cooler temps? What's his over boost set to and what's he hitting?

Pretty much rock solid 14psi with the open loop settings. Nowhere near overboost (220kpa). This was much more subtle, overboost is sudden.
I'll try changing the minimum and see what happens.
Looks like we need to play with some plug gaps and dwell settings and see what happens. Maybe get a knock sensor wired up.

Maybe the overly rich AFRs (gauge usually reads mid-10's in boost) and shorter trips have toasted my plugs. Will try a new set of plugs... But I doubt that's the issue. It did exactly the same thing at 12 PSI. Uploading a video of it.
Edit: video does nothing,can't hear the difference in the video. No bucking or anything. Just engine sounds different and makes less power.
Thanks for the help gents.

That's a good point ed, just run a bunch of ping until your motor explodes. Best idea ever.
Wideband is a AEM uego, so only 10-18.
Are you on the GM coils yet? New plugs can do wonders especially after how poorly it was running while we were initially tuning. Throw some new ones in and see what they do.

GM coils are hot, should be able to fire a .030" gap at 3.5ms dwell at 20+ PSI boost. I'd make sure your gap is reasonable.
If the motor pings on 12 PSI boost with more than 8* of timing at redline, something is WRONG. Does it detonate with more timing? It will have retardedly high EGTs running 8* timing in boost, I played that game running 28 PSI boost on 8* on pump gas, burned up all 8 exhaust valve stem seals in one night of racing at the drag strip.

I can link you to another BP that ran single digit timing that burned all 8 exhaust valve stem seals up too if you like.
