I have a 2002 ranger 4.0 4x4, with a 2006 4.0 motor, do I need to replace the 2002 ecu with a 2006 ecu? Does that fix the egr issue? Also I noticed the egr hard line needs to get rerouted around the oil cap right? A couple 45s and 90s should work with no issues? Please advise

 

whats the problem? does it run?

 

No, on the computer, couldn't use a 2006 computer in any case

Yes, is there a running issue or any Codes?
