Newbie - Looking for Some Guidance...
Hello All, this is my first post. I am in the North Florida area and I just recently bought a 2012 Ram 2500 Outdoorsman with the 6.7 Cummins. It has about 128,000 miles on it and has had some deletes done, etc. My issue is that I have no experience with Ram Diesels and do not have baseline to measure the truck against so I can't tell if its running right. It's my first diesel truck but I have a lot of experience with gas motors and a little experience with marine diesels.
The truck I bought has a factory exhaust brake but I can't tell its doing anything when on. I am also throwing various codes (mostly egr stuff) and getting an EVIC message that the exhaust needs servicing immediately. I have done quite a bit of research and spent some time going over, under and around the truck and I figured out it has the following:
I've changed the CCV filter and that's about it. I want to get the codes sorted out and get rid of the EGR stuff and get this thing running clean, strong and efficient. Questions: 1. Could my exhaust brake be unplugged or malfunctioning explaining the EVIC message? 2. Should I try and update the XRT and re-flash the ECM? 3. EGR and throttle valve delete or new intake horn? 4. Could the motor be starving for fuel? I was thinking of a fuel filter mod and big line kit but will this be enough? 5. The trans seems to shift fine, but under hard acceleration the later gears shift too soon I think. Would a trans tune fix this and is it worthwhile? Any help would be greatly appreciated and thanks in advance! :thanks: |
First I would record the codes then clear them and see what comes back, that way you will know which ones are current codes and not from when the truck was first deleted. You can check the exhaust brake by listening to the tail pipe with the brake off then turn it on and the sound should change to almost a whistle. Definitely update the H&S and their transmission tune works wonders and in my opinion is worth the money. I would get rid of the egr cooler and change the intake horn. Take out the pressure/temp sensor in the intake horn and inspect it a new one is under $50, it's the one on the rear and has a single torx screw holding it. Welcome to DTR.

Okay, the exhaust brake is working for sure now and the codes are all gone along with the EVIC message. I updated the XRT Pro and then re-flashed and it seems to have cured the codes and all. Also the brake whistles loud now when idling so its definitely working.

Removed and cleaned the MAP sensor and you were right, it was gummed up pretty good. https://www.dieseltruckresource.com/...milies/yuk.gif
Worries me about how the rest of the intake/exhaust looks... I removed the power puck and the BD power adder that was plugged into the MAP sensor. The original owner had several power adders stacked up on top of the XRT Pro... So far no codes or messages and its running better. Still not a lick of smoke either...:thumbsup: Thanks to all for your help. :thanks: Now on to adding gauges in a dash pod so I can see what she's doing and getting the cooler out of there... :cheers: |
