The CCV system is garbage on this engine and lets oil mist blow by, which is sucked back into the clean air duct just before turbo compressor. You will find quite a bit of oil in the bottom of intercooler, some of that blows back into intake manifold, then mixes with egr soot to create a black...
We met our national NOx targets for air quality way back in 1995 for the 24-hour limit of .053 ppm and 1-hour limit of .1 ppm. All the EPA regulations since that time have further reduced NOx at the cost of raising CO2 about 20%. CO2 is the main driver for climate change...EPA is technically...
That is the same disclaimer all the tuners used, for off-road racing usage only. It did not stop EPA from going after GDE. At least GDE tunes reduced CO2 by 18%, the rest of the tuners tend to increase emissions as they have no idea what they are doing.
The swirl ports are used during FTP75 test cycle. Intake throttle is used on all the EPA test cycles. EGR is also used on FTP75, HWFEC, US06 and SC03 test cycles. Where did your information come from EPA that it is not emission relevant? I would like to see that and take EPA to task.
Give GDE a call or send an email today. FCA has a learning correction for the mass air flow sensor on GEN2 engines. They did not implement this on the GEN3 platform. As engine ages, the correction tries to simulate an ideal engine, which seems to lead to P026D and P026C codes on many...
That is why I replied, his answer was misleading as it was not related to a Gen3 Ecodiesel. Gen2 and Gen3 are completely different for hardware and calibration.
FYI, the OP is asking about Gen3 ecodiesel, 2020-2023 model years. A completely different PCM and vastly different powertrain than what is in teh Gen2 ecodiesel 2014-2019. The Gen3 tuning works very well!
This will be like buying a new truck and it will run much cleaner than factory. https://greendieselengineering.com/product/ram-1500-ecodiesel-tuning-performance-fuel-economy/
Who did the tuning? That is what most likely lead to the engine failure. The delete tunes on Gen3 ecodiesel are made by clueless people. Most are just turning off egr and def and sometimes dpf. There is high pressure and low pressure egr on this engine. Turning off the egr effectively...
