G4X ECUs have up to eleven digital inputs. Unused analog input channels can also be used as digital inputs. Digital inputs are general-purpose outputs that can be used to supply the ECU with a wide range of information.

The following limitations apply:

·DI1-4 must be used for VVT Signals

 

Any Digital Input can be used for frequency/Duty cycle signals, the maximum readable frequency is more than 10kHz (Can read higher frequencies depending on signal amplitude).

The digital input Switch On Voltage is 1.8V, Switch Off Voltage is 1V.

 

MAF and Throttle Safety inputs can be either analog or digital (frequency) inputs depending on the vehicle, the help for the MAF input is here and the help for the Throttle Safety input is here.

 

Refer here for more information on CAN DI and CAN DI Frequency inputs.

for specific wheel speeds inputs go to chassis and body, for cam sensors inputs go to vvt.
