Question about reading a datalog.

[mustang_marc]

In terms of reading the knock sensor...what does -0.25 (this happened at WOT from 5300-5500) and -.75 (not WOT...but driving from 1600-2100 rpm) represent?

That is how much timing the PCM is pulling with the knock sensor, but the cruising one is weird. What is your air/fuel ratio?

I'll have to go back later and look at what I logged. My first time to ever really play with the data logging software. I selected a punch of PIDs that I thought were useful. I was just bored last night. I need to get with the tuner and find out what all they recommend to log.

Which data software??
