OK, I have searched etc - Found the ecu pinout info in Technical, but unfortunately it doesn't help me, or maybe it does & I'm just stupid today. A couple of hopefully quick questions;
Can anyone tell me what each of the 4 wires in the O2 sensor are for - Yes, I know that it has 2 grounds, a 5v signal & one to the ecu, but which way around for each of them? I don't want to end up putting 12v (or 5v) down the wrong way of a current loop, as I assume that it would be . . . bad.
Secondly, once I get the O2 operating, what sort of signal am I going to get out of it - I know that I am after an air-fuel ratio of 14.7:1, but what does that equate to?
I.E. I am going to get a value in the EMS Tuning display of "Insert bad number here" & I will need to auto-tune it to "Insert good number here".
Can anyone tell me what the "Good number" is? :(
I have a B18C5 Type R (I think - It's a 1999 JDM B18C), running with an EMS 8860 ecu.
