^^^ Yes. Pulse width, the [U]time[U] the injector is open. I'm just trying to keep it as simple as possible with the learning curve and language barrier
Datalogging with a wideband O2 is vastly faster and more accurate. WELL worth the small expense.
You can add a bung in the head pipe to datalog the front separately if you want. Twice the trouble for 2% accuracy (Based on the front fuel table usually being set 2% different).
Yes, DDFI-3 has at least one extra pin for analog input.
You
can datalog and tune with a NB. It will take much longer, but IMO it will end up being accurate enough for smooth running and long as you allow the ECM to make EGO and AFV corrections afterwards (not locking it out).
IMO,YMMV,IIRC,LOL
