No thats fine its why I said imo rather than saying its fact. Personally I've seen in person two sets of je pistons that had at least one piston in the set that was not round. Neither set was for a miata though. I know of one engine builder that also refuses to use then and his current ash tray is a JE piston. There are many je motors out there working just fine though so gets hoping you have better luck.
Keep in mind I'm using supertech pistons in my motor without issues. However my next motor will likely be built with mahle or arias.

And the tuning is done by human, not in software. I am much more interested in continuous onboard looping data logging, gear or VSS related boost, extensive tests and diagnostics, CAN output, etc.

Well, I had MS1 so I needed to upgrade to a new platform anyway. The price difference between doing MS2 (or your version of it) or a commercial (and well known and well supported) system like DTA is not that huge.

All I know is that most people running DTA ask me to pull it out and install something else as there is no one that seems to getting it right before the engine dies on the dyno. But you have to put that in perspective: A car that performs on the TRACK can be a total nightmare on the ROAD. A well tuned car that is performing nice on the ROAD will do a good job in little dyno time on the TRACK. You could say a ROAD car is more demanding then. I have found most of the dyno-only tuned cars aren't running well at all and if you have a system like DTA it is very hard to get a nice tune for the road. Running an engine WOT is always easy, just open the injectors long enough and put the right amount of timing on it. Your demands are probably minimal so the DTA might work for you after all.
But I am not trying to start a discussion here at all... Just let us know how it worked out for you, we might learn something from it. Keep building, keep posting.

Updated the first post (here: https://www.miataturbo.net/showpost....12&postcount=1)
The 94 engine broke down due to bearing #3 failure. Root cause was determined to be temporary oil starvation. Long left sweeper ending in heavy breaking zone is probably what triggered it.
More enhancements:
- Maruha Racing Oil Pan Baffle IN STOCK
- Ishihara-Johnson Crank Scraper ORDERED
- Boundary Engineering Chromoly Racer Oil Pump Assembly, 1 shim ORDERED
