Hi guys

I'm doing finishing wiring of my EC2 / EM3 setup.
My documentation is quite old and I'm wondering if anyone has more recent derivatives of Tracy's documentation.

I'm particularly interested in Tracy's latter code that I understand included a closed loop fueling scenario. As I understand closed loop, he would need an input from an O2 sensor. Is this information coming from the EM3's O2 input or is the EC2 reading an O2 sensor directly itself?

Thanks very much.
