Dodge Cummins Comp Box Features:
Comp features five power levels with power gains from 40-120
horsepower. Each of the five power levels has an independent
five-level adjustable responsiveness setting, providing for
a total of 25 levels of adjustability! The responsiveness settings
enable you to dial-in the optimum balance between responsiveness
and low boost smoke control, no matter what additional power
modifications have been made to the engine. The Comp module
is fully adjustable on the fly and mounts inside the cab.

and easy installation
1-3 on the Comp will provide de-fueling below stock. The de-fueling
mode is entered only when rpm and boost are below a set value
and stock fueling is being increased beyond a set rate. These
conditions are different for each sub-level 1-3. During operation,
when the de-fueling mode is entered, the rate of fueling increase
is limited, which reduces smoke. De-fuel mode is exited once
stock fueling equals the fueling controlled by the Comp. This
way the transition is smooth and cannot be felt while driving.
De-fuel mode is entered the easiest in sub-level 1 and has
the smallest allowable fuel increase, while sub-level 3 de-fuel
mode is not entered as easily and has a larger allowable fuel
4 and 5 allow adjustment of the additional fueling above stock
based on boost level. Sub-level 5 adds the most fuel at low
boost; Sub-level 4, which adds less fuel than Sub-level 5,
corresponds to jumper setting 2 on the EZ.
of additional fuel added is calculated, the amount actually
added after being compared to boost from the total is as shown
1: 33% is added at 0 psi boost
100% is added at 20 psi boost
2: 50% is added at 0 psi boost
100% is added at 15 psi boost
3: 67% is added at 0 psi boost
100% is added at 10 psi boost
be added at 0 psi boost on all Sub Levels and EZ Jumper settings
unless the de-fuel mode is entered as described above.
Level 1 on the Comp is the same as the EZ; on Power Levels
2-5 additional power is added via the wire tap onto the injection
pump. If the pump wire is not attached with a Comp, Levels
2-5 are still operational, but the power gain is not any higher
than Level 1. Under this scenario, however, power will come
on much earlier in the throttle.
