You're alive!! I was wondering.
What is the MS's RPM limiter set to? RPM limiter is set to 7200, and the boost cut is 280kpa. |
Check/disable launch control. If OP had it enabled, it could be grounded by mistake.

I'd also recommend a smoke test at this point for boost and vacuum leaks. Glad you got ride of the oil/smoke problem and can continue making sure things are all setup correctly. I would venture your TS settings are pretty good since you didn't make huge changes from PO's setup. Make sure the boost controller-to-wastegate vacuum line are plumbed to the right port on the waste gate. Keep the criticism to something objective and helpful, not snarky and useless. |
Well, I'm glad that got sorted.
Any chance you can get a log of it "hitting the wall" as it were? Post it up and lets see if we catch something you missed.

In for 25psi vids of glory |
I agree with turning off launch control.... My MS did the same exact thing and that is what solved the issue for me.

No launch control active. Maybe spark plug blowout? Gapped at .40 at the moment. Maybe .20?
If it is rich enough you may also be getting into a rich misfire. My Volvo does it but it is in the 9's AFR when it happens. Surely you would notice it on the wideband. |

If stock coils then yes. You'll get blow out above 10psi or so. So gap down to .030 or upgrade to cops. If you already have cops, which I think you do, then that's not the issue.

I think I was getting some fouling..... Time to break out the wire brush. https://www.miataturbo.net/attachmen...ine=1403495897 |
Your spark settings and dwell, what are they?
|
Spark plug gap is .40. I believe off the top of my head my dwell is 2.2.

Number of Coils should stay wasted spark
edit also cranking dwell should be 3.5 and set your Nominal Dwell to 2.1 and while the car is running adjust your dwell correction curve |

So I shouldn't adjust the gap to be more narrow with sequential Toyota COP?
