I like to apply Diaelectric Silicone Grease to all electrical connections. Water proofs and non conductive. Also check active voltage with DVM.

I take the supply fuel pump to mean the lift pump from the tank, its looks good. The CP4 sounds OK for cranking although I see more like 28,000 psi while running. Can you scope the span width and pulse of the injectors while cranking? Try a shout out to GDE they have come up with a couple of...

Wow that is a new one, never have seen or heard of that one. Had to dig to find it. OK lets start that code is referred to as "Reductant Heater Control Module Supply Voltage" it means that the module is receiving too little or too much voltage. You will not be able to just clear the code and go...

I agree with John, but I would add find a different dealer to perform your warranty work. If the diesel tech doesn't have a clue as to how to diagnose an eco then you will never be happy. By the way what is the CEL for, have they told you? Most of the issues I have had with my eco have been...

Forgot, a side note the guys at GDE are all former code engineers from the Big 3. You should get along just fine.

At present she has the OEM tune. This version there is little to no turbo lag and runs out on the highway just fine. Fuel mileage avg. about 24 mpg. There is a noticeable punch at 2K rpm as the Turbo spools up, kind of begs why a variable van? If we had not experienced the improved HP and Torque...

Looks like a list that I used to get when someone brought an engine into my shop for rebuild. Depending on where you live, emissions test or not, your delete with straight pipe will not work, however if possible will require computer tune. This has limited options. New turbo, from what I have...

To clarify; we had the reprogrammed ECM, when FCA installs the AEM it overwrites the tune. GDE developed an EPA Compliant Tune after being slapped with Administrative fines and Cease and Desist Order from the EPA. They now offer the EPA tune via a hand held tuner, I have retuned my truck but not...

Stealership absolutely. If they repaired the vehicle there is no way they should return it to you in "Limp Home Mode", that just sets the truck up for a cascade of DTC's. My 2014 finally lost it's tone ring magnet, replaced under AEM II warranty, I did have to pay for the tone ring as it was not...

I have run two sets of those same tires, great for regular driving, not so much for towing. Just put on a set of Pro Comp A/T's E rated Light Truck tire, much improvement in stability. Under 65mph, good WDH hitch, E rated tire, trailer brake, I run mine at 7.5% gain on two axle 8K lb tow hauler RV.

Solution: Green Diesel Engineering EPA Compliant Tune.

Green Diesel Engineering EPA Compliant Tune, no more error messages.

My 2014 RAM and my wife's 2015 JEEP GC both have the GDE tune. Wouldn't drive without it. No "Service Electronic Throttle Control" error messages. Better power curve and torque curve along with more hp and torque, improved fuel mileage. Only draw back in the EPA Compliant Tune is that DEF is...

Wow!! Assume picture. I have only witnessed this type of wiring "repair" when the gang plug has corrosion or bent connector pins. I would agree partially with Tremper126, You have additional electrical issues. First: the first three codes if not corrected at the source, will result in a "Limp...

NIck welcome to the board. Including my 2014 RAM my wife drives a 2015 JEEP GC with the ecodiesel. We both have the AEM recall and she just got the EGR recall completed. We both had the same issues with the AEM, just to different degrees. Hers less than mine. We both had been running a Green...

Wow, what a plethora of codes and a common running issue. Let me start out by asking who did the delete tune? We have run up to multiple programming issues from switching from CNG only to dual fuel or CNG to gasoline only, with a time period of running then the issue exactly as you described...

I have the GDE tune and I love the power and torque increase as well as mileage increase. My Oil Analysis has shown a continued cleaner oil sample since the tune install. GDE claims a lowering of soot through the EGR diffuser due to improved fuel mapping, I have not inspected my manifold since...

I just looked up the Pennzoil Euro Full synthetic, it is now available in the required 5w-40 for both the ecodiesel and the Cummins. However of the multiple specifications listed by RAM the oil only meets one the ACEA A3/B4. I am not sure if one is enough, the verbiage from RAM is "meet Material...

With the advances in electric mileage between charges it looks like that may be happening by default as well as local government fiat. As long as no looks behind the curtain at the abysmal environmental impact of mining and production of Lithium Ion batteries and definitely not at disposal...

You refer to and yet denigrate the success of the EPA air pollution controls since the mid 1970's. Vehicle exhaust emissions have been reduced by a factor of several 100's, yet you state that vehicle exhaust is still the big bad source. What you may have missed during the years is the change in...
