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. Eliminates downshift hesitation at low speed tip-in maneuvers i. The tune combo has provisions to allow our 88 C thermostat to be added separately.

Overall I'm very impressed with the driveability improvements of the tune and the added power.

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.

If you're familiar with those interstates they're certainly not flat - you're either going up a hill or down with some of the grades in Central PA being pretty long if not high. The upshifts are former and sooner under light throttle and it just pulls using the added torque. Site Vendors. Engine braking can occasionally feel in normal driving, more noticeable towing the trailer. Of course, their new engines have turbines designed for the higher temps and changes to cylinder head stiffness for peak firing pressures. Accelerating is much, much smoother and it has more pep for sure. It's not about the money - I simply do not want to get ripped off.
