For today’s test I increased the pressure delta. One test (pictured) had no TMA at all (yay)
Boost comes right up, and torque is pretty flat. Cooler day, so almost SAE1349 conditions with a small correction factor of 0.2%.
The other test sample for today does show some TMA.
The rate of increase may be addressed now, but I note that the new TMA happens when Cylinder airmass exceeds 1.32. More study is needed; that is below the current tune knock airmass table. I suspect this is a 3rd source of TMA however.
This chart compares total cylinder airmass with boost and TMA
