Timing

After your second test drive, you can replay the log on the computer in the comfort of your own home, and just look at the values next to these additional five channels to see if any of them are making any changes to our base timing:

Fuel / AFR
IAT
ECT
EGR
Catalyst Heating

And or you can clone the Timing Advance graph for each one of these to Geek out even more. It is a bit more work but it will show you exactly precisely where the timing is being altered.

Let's clone/copy one graph together. Let's make a graph for ECT Advance (which again in the graph wizard HP Tuners calls Coolant Advance)

All we have to do is change the following:

Label: Coolant Advance

Parameter: Coolant Advance

View: over on the right hand side we can choose how to show our data the default being Average but if you want to scare yourself a bit especially when it comes to engine knock change that pull down to Max, ha ha

and we are done and ready to see the results on our newly cloned graph
