We have tables that we think are related to EGR in our test builds. We will expose them in a future update if we can confirm that after testing.

IMO reducing EGR amount (as SH engine's deNOxing only through uncommonly cooled EGR) would be good step to improve combustion efficiency and reduce EGT mentioned in your last article. At the cost increase of NOx emissions, of course... 8-)

Nice links, especially the 2nd one. Is there a workshop manual or any other documents that would go into technical details about the operation of the 2.2D SkyActiv Mazda engine? Any pointers would be much appreciated!

Sorry, we do not have any news on that. The rumor has it that Mazda will start selling the 2.2l diesel in the US. It will be much easier for us to obtain a test vehicle and do some serious tuning on the dyno and add features.
