Mp8 egr, dpf delete

Recommended Posts

I have a 2009 cxu with mp8. I just had egr and dpf deleted. My water temperature is running hotter than normally would. Any ideas as to why?

The engine is designed to have exhaust gas in the cyl this cools the burn! You have now removed that and if the tune wasn't compensated for this it Is going to run hotter with clean air going into the cyl !

just sayin!

Akzo diesel,  they're saying the water temp isn't affected by the tune since it's  not throwing any codes.

May have been a coincidence! who knows maybe  Try a stat! Log as the temp is in the safe range should be ok! one thing for sure getting dealer help is out for ya now!

The max HP rating for a export MP8 with no EGR is 440. I’ve seen 3 major engine failures on low mileage deleted MP8s . One I know was a 505 , the other 2 I’m unsure on HP. I would feel better if the EGR was not deleted but the DPF/SCR was

Why would no egr affect the motor? Wouldn't it be better for the engine to be deleted?

Milkman!  If I under stand it correctly !  with no egr if the fuel/and timing are not dialed back properly the heat in the cyls exceeds what the engine can tolerate ! It can burn up pistons crack heads bla bla bla ! recently  I have seen  several ISX engines heads  cracked and ruined due to this delete  And no alteration of the ecu! One needs to research who you are dealing with when doing a delete! We have guys that have successfully deleted here but the tune was altered to suit!This is all well and good till big bro starts enforcing the emission laws then were going to have issues!  Also The down side is  you now have no dealer support when it come to repair! your on your own ! Just Sayin! However you have the advantage of less break down due to emission related issues!And that CAN be A big Bonus if you don't get thrown under the the bus wheels!😉

I've been hearing of deleted Volvo engines having the same problems. Seems a lot of the hackers modifying the software to delete emissions are mucking about with code they really don't understand and making things worse.

We saw burned valves , cracked liners and cracked head. To much fuel and clean air and they burn pretty hot.

When doing the tune sometimes the type of fan gets changed in the programming.  There are 3 types.  Viscous, air, and electro- viscous.  What type do you have?  If the computer is programmed wrong it will not turn the fan on.  Does your fan work?

I did quite a few of those, and never had a single issue.
The guy that does them for me, states in his instructions that you should verify that engine fan is working after the delete.
Also I remember that he told me that there is a parameter on which temp. fan kicks in, you can change that in ECM.

Did you block off the egr valve and should it be blocked off on intake side as well?
