I fully understand the fuel transient theory, but as some others, I would like more in depth info regarding adjustment of these tables. Is there any way to "tune" these besides blindly add, subtract, multiply, divide? As it is, we can not scan these tables, only log Commanded AFR and Actual AFR and watch the lean spikes and/or rich dips. I don't mind playing around with these tables (although conservatively), but I prefer to understand the how and why of changing these values. So I ask our more knowledgeable experts here (those who look inside the PCMs ) if they can share their infinite wisdom with us.Originally Posted by HPTuners Help File
