And is it only at idle that this rich condition occurs?

About the data logging with the E-manage, is the information conveyed in the logs what the ECU thinks is going on, what the e-manage is telling the ECU is happening, or some combination of that information?

For example, if the stock ECU wants to run 10 deg of timing at a given load point, and you are using the E-manage to add 5 deg of timing at that given load point, does the log show 10 deg (what the ECU wants) 5 deg (what the E-manage is adding) or 15 deg (combo of ECU and E-manage)?

One last thing about the Boomslang harness, it has options for "air and water" "knock and water" "knock and air" or "dual knock" inputs. I assume (tell me if I am making an ass of U and Me here) that for the air and water it is talking about temperature? And that in our situation we would want the knock and water as the best choice of what to monitor.

Thanks,

OBD1/2 dataloggers will show what the ECU wants target timing to be, not actual. Some obd1 Dataloggers are off too.

With the boomslang harness you want Knock/Water temp if you plan to use greddys autotune feature.
