Wiring is not polarity sensitive.
|1||Any Spare AVI*|
An AVI with a selectable Pullup should be used. If not and external 1k pullup to 5V should be connected.
Calibration: Use "Temperature - xxxxxxx.cal"
Created for Haltech ECUs using a 1k pullup to 5V
Although most users of Haltech ECUs will be deleting the MAF, it is possible to use a MAF if you prefer.
|4||Signal 0-5V (AVI)|
The G13B comes with a heater-less single wire Narrowband O2 sensor. It is advised to not use this sensor and instead swap the sensor for a Haltech WB1 kit.
Adding a Haltech Wideband Kit (highly recommended)
For correct operation a Haltech WB2 kit is highly recommended for this application, with the provided 4.9 sensors replacing the pre-cat sensors. Swapping the sensors is accessed only from below the vehicle. Sensors use a 22mm socket or spanner to remove and replace.
Vehicle Speed Sensor
This engine uses a Hall Effect Vehicle Speed sensor that is located on the instrument cluster and is driven by a cable. A single wire is sent out from this to the ECU.
The OEM ECU provides both the 12V+ power and the ground signal to fire the injectors. There are two power pins and two signal pins, however both power supply wires join to a common wire, and both output signal wires join to a common wire, so all injectors will fire together.
It is recommended when wiring your Haltech ECU to run one ECU injector output to one injector.
The injector flow rate is measured with the injectors held wide open at 100% duty. For fuel systems with a fixed regulator pressure (often returnless systems) that is not referenced to manifold pressure the flow needs to be mapped over Manifold Pressure for accurate tuning.
Injector flow rate = 200cc/min
Injectors are 2.2ohm so the injector current control should be set to Low.
OEM ECU Information
The OEM ECU is located in the Left Hand Side of the dashboard

Please double check ignition and injection settings before uploading.
Using the wrong settings can damage hardware or the ECU.
