Below are the power/torque curves for the soon to be released GDE turbo kit. It is a replacement unit for the factory part. The performance is phenomenal! The tune for this part allows for three power settings: Tow (active with tow/haul button), Normal and Overboost mode. With the kit will be a...
There is an oxidation catalyst just in front of the dpf, both are in the same can. If the cat is not working correctly, it could lead to failed regens and subsequent plugging and code. Being a repeat issue, the dealer should take proactive action and replace the dpf. Do you pull trailers much...
We will find the happy balance for more effectiveness at lower rpm without impacting city traffic driving. Maybe more braking down to 1800 rpm in gear 5 and 6, then a bit higher threshold in gears 3-4.
The cruise control uses a PID control loop to govern the set point speed. The stock tuning is very aggressive and holds speed within 0.5mph of the set point. This leads to more fuel burn during cruise. The GDE tune relaxes the governors a bit and the speed will fluctuate +/-1.5mph around the...
We do not recommend k&n style filtration on a turbocharged engine. The hi-flow filters do have less pressure drop, but they let larger particles through the media. These particles can reduce turbo compressor life over time. Naturally aspirated engines can eat the larger particles without...
My guess is they never thought about it. The Garrett turbo used on the VM motor is designed to handle engine braking, the critical factor is drive pressure not to exceed about 3.5 bar if I recollect correctly. The exhaust temp limit pre-turbo is 850 C or 1562 F. The engine self regulates this...
For some clarification, if you are in cruise control with the stock tune going down a grade and start exceeding the vehicle speed set point by 3-5 mph for a certain time period, the trans will downshift one gear, then after a little more time downshift another gear. It will keep down shifting...
We just signed up to this forum and can answer questions pertaining to the GDE tune. To date our customers have accumulated almost 4 million miles running the GDE tune and no issues. Our main goal is improving engine longevity while increasing fuel economy and upping the power/torque to the...
We just signed up to this forum. Our Ram is a 2014 with about 35,000 miles on it and running like a top. We provide fully developed engine tuning for the Ram ecodiesel at www.greendieselengineering.com and can answer questions for those that are interested.
Thanks
GDE Team
