Does the oem ecu record the egr data position, why I ask is when using the egr by pass modul on the maf to trick the egr valve from opening, can the dealership check the ecu if the egr been tampered with if the car needs to be taken back for warranty claim.

On Techstream you can see what the EGR valves are doing, so I guess they would be able to see. What module do you have? Wouldn't mind doing something with the EGR on my 79.
