My guess is the EC2 pin28 connection is for some other = application without the EM2. In my manual that pin 28 is for "Future connection to = fuel flow instrument". Al G Another question that may be more suited for Tracy (but I hate bothering = him ever and I still hope to make progress while he is away), however, I = was re-reading both the manuals for the EC2 and EM2 and looking at the=20 pin out sections for the d-sub connections. I noticed that for the EC2=20 it shows pin 28 being for the O2 sensor, however, in the EM2 Manual it=20 shows pin P2-8 as also being for the O2 sensor.=20 Currently mine is only hooked up the the EM2 P2-8 pin. I do not ever=20 recall that there should be two O2 sensors installed and I was under the = impression that you would not have two leads off of one sensor to two=20 different instruments. So, what line of text did I miss (not unheard of = and one of the reasons I keep re-reading the manuals....as I experience=20 more, some of the stuff makes more sense with an additional reading even = though I doubt I will ever "get" the calibration stuff...sigh) about=20 where the 02 sensor should be connected to. Is it preferred to go the=20 the EM of the EC....or do you have a two wires from 02 sensor, one to=20 the EM and one to the EU....or something else all together?=20 Thanks.
