Engine/Transmission (1998.5 - 2002) Understanding the Edge Comp.

[MikeBeggy]

I just completed the install of an Edge Comp. Does anyone know if there's a chart to show what the box is actually doing at the different levels and subroutines? Is the timing being changed, fuel delivery, etc. Maybe this is secret stuff and is not available. Thanx.....

I would try Edge's website and ask on their Discussion forums.

Got this from the Edge Products Forums





There are two types of levels on the Comp Power Levels, and Sub Levels. The Power Level sets the power increase under full boost that the Comp module will add, regardless of Sub Level setting. The Sub Level settings allow for adjustment of low boost fueling eliminating smoke if larger injectors or turbos are added.



Sub levels 1-3 on the Comp will provide defueling below stock. The defueling mode is entered if three conditions are met: rpm and boost are below a set value, and if stock fueling is being increased beyond a set rate. These conditions are different for each sub level 1-3. Once defuel is entered the rate of fueling increase is limited resulting in the defueling to reduce smoke. Defuel mode is exited once stock fuel equals the fueling from the limited increase, this way the transition is smooth and cannot be felt while driving. Defuel mode is entered the easiest in sub level 1 and has the smallest allowable fuel increase, while sub level 3 defuel mode is not entered as easily and has a larger allowable fuel increase.



Sub Levels 4 and 5 (and EZ jumper settings 1-3) allow adjustment of the additional fueling above stock based on boost level. Sub Level 5 (EZ jumper setting 3) will add the most fuel at low boost, Sub Level 4 corresponds to jumper setting 2 on the EZ. The amount of additional fuel to be added is calculated, the amount actually added after being compared to boost from the total is as shown below:

EZ Jumper setting 1 33% is added at 0 psi boost

100% is added at 20 psi boost



EZ Jumper setting 2 50% is added at 0 psi boost

100% is added at 15 psi boost



EZ Jumper setting 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 defuel mode is entered as described above.



Power Level 1 on the Comp is the same as the EZ, on Power Levels 2-5 addition power is added via the wire tap onto the VP44 injection pump. If the pump wire is not attached with a Comp Levels 2-5 can be ran, but the power gain is not any higher than Level 1, the power will come in much earlier in the throttle but overall gain is the same.



Hope this helps

Very nice explanation and really clears up the mystery of how these boxes work. Nice job

Thankyou for taking the time
