LEARN DATA

The ECU has several functions that “Learn” what the required settings are based on sensor signals. The fuel learns how much correction is neede...Read more

FUEL PUMP CONTROL

The FiTech ECU for Go EFI systems has a special driver circuit that will drive the fuel pump directly, which means that an external relay is not ne...Read more

FAN SETTINGS

The Electric cooling fans can be controlled separately. Just a reminder – the system only controls a RELAY. DO NOT CONNECT DIRECTLY TO THE FAN ...Read more

IDLE CONTROL

An Idle Air Control (IAC) stepper motor valve is used to open or close a passage in small increments (called “Steps”) that adjusts the amount o...Read more

AFR CLOSED LOOP

The system can sense the lambda in the exhaust system from the wideband sensor. The lambda is converted to an approximate AFR (Air Fuel Ratio) assu...Read more

CRANKING FUEL

The fuel requirements during cranking are very far from the speed density calculated amount. Thus, the fuel is not using that equation during the t...Read more

REV LIMIT DECEL CUT

During certain situations, the injectors can be turned off. At high RPM, the injectors and spark can be cut off at the Rev Limit RPM in order to pr...Read more

FUEL CONTROL

A speed density algorithm is used to calculate the fuel injection pulsewidth. The temperature used is called the “In Cylinder Temperature” whic...Read more

ACCEL PUMP

Intake manifolds are going to get wet with fuel while running. This wetness changes with temperature, engine vacuum, and air flow speeds. This wetn...Read more
