I would like to close my EGR valve so that only "fresh" air is in the comubstion chamber.
I read my ecu file (EDC15c2 on Puegeot 307 2.0 HDi 90hp) and I located the three bits "EGR Swtich with/without". They are by default equal to 001 so I will put 000 instead and write the new ecu file using MPPS.
Do I need to do any physical change to any component of my engine after this modification ? Are there any points I should pay attention ?
