Can anyone here or GDE confirm if the swirl motor is disabled standard with the Eco-Tune? If so, any insights to why, other than for those having issues with theirs?
I only ask because if the motor works, and the EGR is shut off then no more oil should be misting into the intake hose and then leaking down onto the swirl motor, right?
If that's true, and it may not be, but wouldn't the swirl motor improve low end responsiveness?
I'm pretty sure Eco turns off the swirl standard.... don't know about EGR. BUT...you will still get oil in the intake hose. Take a look at the source of the oil. See the vent pipe coming out of the passenger side of the head and going right into the turbo intake. Only cure for that is an Elephant Hose Mod, or a filter to clean up the vented air. I did the EHM and get no oil in my turbo.... its not for everybody. Oh, you can also upgrade the intake gasket.
As to the why.... its because the Swirl Motor is such a PITA to replace and they all seem to go bad at an early age, especially if you have the oil problem. Dealers charge anywhere from $1200 to $3500 for the job and if you don't watch them closely, they will pull your engine to do it. I replaced mine for about $400 and did the job myself. It was difficult. Then I bought the ECO Tune a few months later...so now I have a new swirl motor that does nothing..... but I'm happy with that. If I had known about Eco before replacing the swirl, I would not have done the replacement.
