Spark Advance.. and other OBDI info analysis requested
OK i have built my own OBDI reader (laptop) and its pretty sweet but i have some questions i wanna ask.
My spark advance is up at or above 20* quite alot. And my O2 sensor readings jump alll over the place, is it normal for them to bounce around or does that tell me i need a new one? And what does "ESC Count" mean? and is it normal for it to climb to like 90 or so in one decently hard trip? Thanks for hte hep and i know i will be back with more questions as i figgure this things out
