MAP Sensor
These engines do not come with a MAP sensor. The EVO 9 has a MAP sensor but this is not used for engine control.
Use the internal MAP sensor that comes with your ECU. For higher boost levels an external MAP sensor should be used instead, connected to a spare AVI.
Variable Cams
Only the EVO9 variant of this engine comes with a variable cam system. Mitsubishi call this MIVEC and it allow for continuous cam control on the inlet cam only.
Wiring for the intake cam position sensor is the same as for the normal engine exhaust cam position sensor.
The MIVEC solenoid can be directly wired to the ECU using any spare output other than the Ignition Output. The other pin will go to 12V+ switched with ignition.
Idle Valve
This engine uses a Stepper Motor idle valve controlled via the Stepper Outputs. It will not work on Elite 550/750/950 ECU models.
12V+ can be left connection for Elite ECU models. Be sure to check your Drive Type setting to suit the wiring that has been used.
Drive Type: "Low Side" if 12V+ is connected. "Both" if 12V+ is not connected

An AVI with a selectable Pullup should be used. If not an external 1k pullup to 5V should be connected.
Calibration: Use "Temperature - xxxxxxx.cal"
Created for Haltech ECUs using a 1k pullup to 5V
Air Temp
The air temperature sensor is part of the MAF Sensor. If the MAF is removed a new sensor should be added to the intake plenum or as close as possible to the throttle body.
Knock Sensor
The 4G63 uses an older design resonant knock sensor. These are prone to failure and are also only suitable for relatively standard engines.
For heavily modified engines it is better to use a doughnut style non-resonant sensor such as the Haltech Knock Sensor.
MAF Sensor
Although most users of Haltech ECUs will be deleting the MAF, it is possible to use a MAF if you prefer. All models use a Frequency style sensor, so this must be connected to a DPI or SPI and not an AVI as with most other sensors.

O2 Sensors
All engines come with narrow band O2 sensors. These are only suitable for emissions use and are not suitable for engine tuning
Adding a Haltech Wideband Kit (highly recommended)
For correct operation, a Haltech WB1 kit is highly recommended for this application, with the provided 4.9 sensors replacing the pre-cat sensors. Sensors use a 22mm socket or spanner to remove and replace.
Vehicle Speed Sensor
This engine uses a Hall Effect Vehicle Speed sensor.

Injector Data
Flow
The injector flow rate is measured with the injectors held wide open at 100% duty.

EVO 1-4
| 510cc

EVO 5-9
| 555cc

Dead Time
When an injector is commanded to open for a certain amount of time, the dead time is the amount of time the injector is not actually open during this period. It covers the time to energise the solenoid and begin to open and the time to close as well. There are also transient periods during which the injector is opening and closing where fuel flow is not at full capacity so this lost peak flow period is also taken into account.

These models have a different connector with 3x rows of ECU pins.
Location
EVO 1-6
ECU is located behind the passenger kick panel.

Base Maps
Base maps have been created for use with the Haltech Elite Adapter Harnesses and come with the ESP Software package. Platinum Pro - Maps come with the ECU Manager Software.
Where applicable those maps are attached below.
To use these maps they should be IMPORTED into your ECU. Follow the IMPORTING A BASE MAP guide.
