Future TODO:

Change nbo2 to wbo2

Throw out the distributor, and replace with wasted spark coils or COP

Questions:

--How to set up the NBO2?

Config taken from here: http://www.vems.hu/manual/html/ch09s07.html but on test bench MT reads (fast changing) random voltage (2-5V). It seems that the NBO2 input is the 2nd nernst channel (this is correct in manual), but that is pin EC18-1, not EC18-13. When I short this pin to ground, then it reads constant 0V.

So, what did wrong?
