The engine braking feature is a useful add-on for customers that tow often or folks that drive down mountain grades. The feature is active when the following conditions are met: in gears , engine rpm above rpm, and foot off the accel pedal. While the engine braking is active the turbo vanes are closed more to create higher back pressure in the exhaust manifold. This makes it harder to push exhaust out and that force acts on the pistons to help slow the vehicle down. This helps to reduce the need for vehicle brakes and reduces wear on the brake hardware. The feature not active in normal driving conditions. This is a very useful feature for vehicles doing a lot of short trips to drive a bit longer when the regen needs to happen to prevent DPF plugging issues in the field. It is also a cool message to see and better understand what the vehicle is doing. After a successful RACE mode engagement, the function is blocked for 45 seconds. This allows all the shift elements to cool down from the prior use.

We focus on utilizing engineering principles when designing engine and transmission calibrations. Testing and measuring the critical parameters on the powertrain are essential to meeting safety and design limits. Cylinder pressure measuring equipment is vital to calibrating correctly for optimum results. We are a team with numerous years experience working in the diesel calibration field. We utilize a full spectrum approach to optimize the combustion cycle for burn rates, peak firing pressure and thermal management.

The results are lowest fuel consumption per a given load and minimized emissions. To determine the overall power-torque curve to meet the performance requirements, and from that point begin optimizing the calibration as a whole to provide the highest fuel economy lowest BSFC and performance. This involves running multitudes of test cycles on dyno and trade-off curves.

Coupled with the transmission tune, it is like buying a new vehicle. Also, the max power of the engine is achieved as soon as possible with the hot tune and maintained over a plateau as wide as possible roughly rpm. This gives a noticeable gain in the performance feeling of the engine while accelerating. FCA Eco Diesel 3. FCA EcoDiesel 3.

There are no ill effects because "it doesn't soup it up, just provides better combustion and burns the fuel more efficiently. I tow a 6, lbs camper frequently. Just 2 words. About twice a year I have needed to pull the EGR and scrub a whole lot of carbon off of it so it actually works. It is a relatively new release, but after installing I am pretty sure this tune was set up by people that have been in the drivers seat.

Trailer towing is greatly improved with the increased torque, improved transmission shift points, and engine braking for descents. This is an older thread, you may not receive a response, and could be reviving an old thread. The tune does everything it claims to do.

So in my case you treat the cause not the symptom! I have yet to take a trip to get any idea of fuel mileage, but on my short trips I am pleased with the drive-ability of the vehicle. I seriously considered going back to a gasoline Chevy. The answer was "No". Joined Aug 30, Messages 84 Reaction score Throttle response is great! They've tested Sprinters for millions of miles and I think they've come up with a very good "balance" of all the compromises. Shifts are strong and quick, making the truck much more driveable around town. Peace of mind. But thats why I decided to get the tune, as to avoid all that BS that will probably start showing up soon. What is it? It's not about the money - I simply do not want to get ripped off.
