Attitude Box Fuel Controllers


GEN 3 is the short term used to describe the Generation 3 Electronic Fuel Injection (EFI) controller. GEN 3.2 is the same controller, but with a code version update. GEN 3.5 is a complete software and hardware update, which now allows the ability to add and subtract fuel across all vehicles. All the controllers are piggy-back EFI controllers because they do not replace the stock ECU, but rather monitor the signals to the injectors and make fuel adjustments based on the mode settings. Each controller has a push button interface allowing access up to six different modes to allow for quick fine-tuning by the end user without needing a computer.

BENEFIT OF PERCENTAGE FUELING:

Through research and development it has been found that percentage based fueling can offer a more consistent tune-up for applications, which may experience large-scale environmental changes. A few environmental changes to note include temperature and elevation changes. These factors play a large role already in the stock ECU fuel calculations. Fueling a cold motor is different than fueling a warmed-up motor. Fueling at sea level is different than fueling at a mile high.

Offset fueling still has its benefit of being easier to tune since you know exactly how much fuel you're adding. The power of the Gen 3.2 controller is the ability to set each tuning zone independent of the others. The Cruise zone can be offset fuel while the Acceleration and Full Throttle zones can be percentage fuel. This flexibility allows a tune-up to be created which can hold its tune even better through environmental changes. This flexibility is set by Attitude Industries based on each individual application and can not be changed by the end user.

Attitude Box GEN 3.2 Simple EFI Tuning

KEY SIMILAR FEATURES:

  • USES LOAD BASED TECHNOLOGY WHICH IS SUPERIOR TO ALPHN-N TUNING (TPS vs RPM)
  • ABILITY TO MODIFY FUEL WITHOUT ALTERING THE STOCK FUEL MAP
  • CARBERATOR TUNING LOGIC - CRUISE, ACCELERATION, FULL THROTTLE ZONES
  • EASY TO SEE LED LIGHTS TO INDICATE OPERATING ZONE
  • PUSH BUTTON INTERFACE TO ALLOW QUICK FINE TUNING
  • NO COMPUTER OR DYNO REQUIRED
  • EASY INSTALLATION

KEY DIFFERENCES:

  • THE GEN 3 CONTROLLER ADDS FUEL BY OFFSETTING THE PULSE WIDTH A GIVEN FIXED VALUE.
    EX: you can add 1 ms of pulse width

  • THE GEN 3.2 CONTROLLER CAN BOTH ADD FUEL BY OFFSETTING THE PULSE WIDTH OR ADD FUEL BY CALCULATING A PERCENTAGE OF THE STOCK INJECTOR PULSE WIDTH.
    EX: you can add 1 ms of pulse width OR add 10% more pulse width

  • THE GEN 3.5 CONTROLLER CAN ADD OR SUBTRACT FUEL BY CALCULATING A PERCENTAGE OF THE STOCK INJECTOR PULSE WIDTH.
    EX: you can add 1 ms of pulse width OR add 10% more pulse width OR subtract 1 ms of pulse width OR subtract 10% fuel
