    Procedure to disable EGR

    One of the first things I want to do with my custom programming is disable the EGR. I'm trying to find a procedure for which parameters/settings to change but I haven't found anything. I sandwiched a piece of sheet aluminum between the EGR valve and intake to block it off. So far I have increased the EGR On/Off RPM to the maximum values and zeroed out the SA - Spark Retard vs EGR % table. Do I need to modify any other parameters to keep the EGR from changing anything else?

    Max out "EGR - Enable Temp" and that should take care of it.
