Again I should remind: in Russia guys already use knock code for four years. Knock code was prepared by Andrey from Ekaterinburg. And I do not read any complaints about it in their forums. They just use it with their not so good fuel quality....
In official wiki some time ago was 1.1.89 version. I knew who use this code with success. In addition those configs what I see with complaints all was with wrong settings under knock section.
Andrey has also much more stable engine phase angle reading algorithm what VEMS use for injector angle and cam control. Official firmware has some delay for one cycle or one revolution (!) what makes both functions bad at low rpms or high accelerations. (look at VT raeding for sec trigger angle under free rev - it floats a lot!) His reading stays constant like glued (I mean engine with fixed cam, not VVT)
In addition his firmware mod controls automatic transmission on their RHD Toyotas

As I knew he is welcome to share his code with developers. But as we see something did not happening there
