Powering Down
I've recently traded my F-150 for 2012 Dodge Ram 3500 turbo diesel. I've got a tuner which eliminated the O2, with my HOD installed I am getting 17.7 mpg city and 23 mpg on highway. the tuner allowed me to schedule more fuel since it is meant for off road and more hp. It also allows me to have "Zero" added fuel, at that setting with the HOD is where I get those mileage. Now I am trying to find another means to schedule less fuel. Is there any newer model Dodge diesel expert out there or know how to schedule less diesel via sensors on the truck,

RE: Powering Down
You should be able to tweak that down a bit using a MAP/MAF Enhancer. I haven't looked up that truck, so I don't know if it has both devices or not. But I wouldn't try to do both. I usually do the MAF if there is one, and if not the MAP.

Mike,
I think it has two, one on the aribox and one on the intake elbow at the intak manifold. do you have any idea what type they are? I am trying to break the 20's in the city and willuse water injection to eliminate the pre-ignition and lower EGT.

RE: Powering Down
If you're going to use water injection, you can get more aggressive with the MAP/MAF Enhancer.

I don't know which kind you have, but most of them are just simple voltage types that can be adjusted with a home build MAP Enhancer. Have a look at this article: http://www.fuelsaver-mpg.com/simple-map-maf-enhancer .

You should locate the signal wire, and test it. You'll soon see if its voltage or frequency type. But I'm pretty sure Dodge always uses voltage type MAPs and MAFs.
