I dont remember the exact key strokes, but its something like this.
Start car.
Select "Diagnostic"
Select "Real time monitoring" Or something like that
Select "Spark Advance" from the list (or whatever you want to monitor)
Select "Fast sample rate"
Select "No datalogging"
Once youve selected all you want to see, it will have a * by the selected ones.
Hit "esc" twice to get back to logging.
I think next you have to enter "enter" or something, but thats the gist of it. It should beging showing you what your timing is.
These probably arent exact instructions, but it should get you close to where you wanna be. I dont have mine right now to go play and find out, since its at the shop waiting on a custom tune from DS.
Ill find out later if you can tweak a custom tune.
