Sub-levels 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 increase.
Sub-levels 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.
The amount of
additional fuel added is calculated, the amount actually added after
being compared to boost from the total is as shown below:
Sub level 1:
33% is added at 0 psi boost
100% is added at 20 psi boost
Sub level 2:
50% is added at 0 psi boost
100% is added at 15 psi boost
Sub level 3:
67% is added at 0 psi boost
100% is added at 10 psi boost
Fuel may be
added at 0 psi boost on all Sub Levels and EZ Jumper settings unless
the de-fuel mode is entered as described above.
Power 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
