You say "if you command the EGR valve closed..."; it this the same as setting the values for temps as stated above in this thread to the stated values of 300/-40 or is there another parameter that sets the EGR to the state you mention, "command the EGR VALVE CLOSED"??
Thanks for your reply as I do not want to move to a bug smoking killer just yet!
Yes just deactivate it using the temps. Do not disable it by selecting disable in B1501 or you will have a random loss of power and a smoke show while cruising down the highway. I also zero out the desired flow tables but it isn't necessary.
