Only the Elite 2500 ECU model supports this vehicle. Haltech also offers a number of pre-made Terminated Engine Harness options for the Coyote engine.
Sensor Information
Crank/Cam Sensor
This engines uses a Crank Position Sensor and a Cam Position Sensor per camshaft
The crank trigger is a plate that is sandwiched between the flywheel and the crank. It has 36x teeth with a 1x tooth missing gap.
The cam triggers are located on the end of each camshaft and have 7x teeth. This is 4x equally spaced teeth at 90deg to each other, with 3x of those teeth having an extra tooth.
Crank Sensor
A Reluctor crank position sensor is used. This is located on the back of the engine between the flywheel and the block.
Reluctor Wiring
| Pin | Description | Haltech Connection (Trigger 4-core) |
| 1 | Reluctor - | Green |
| 2 | Reluctor + | Yellow |
Cam Sensor
A Hall Effect cam sensor is used. This is located at the back of the cylinder head for each camshaft. Intake cam sensor on Bank 1 is used for engine position calculation (Home).
Hall Effect Wiring
| Pin | Description | Haltech Connection (Home 4-core) |
| 1 | 12V+ Switched | Red |
| 2 | Signal | Yellow (Home +) |
| 3 | Signal Ground | Blue |
For all additional sensors and SPI is used for the signal input to the Haltech ECU.
Trigger Configuration
Ignition Coils and Igniter
The ignition coils on this engine require an external igniter module. Haltech HPI igniter module are a good choice for this.
DO NOT CONNECT THESE IGNITION COILS DIRECTLY TO YOUR ECU
| Pin | Description |

Haltech HPI Igniter
A Haltech HPI 8 igniter is recommended for this application.
See the Haltech HPI Quick Start Guide for wiring information on these igniters.
Dwell Time
DBW Throttle System
This engine uses a single Drive By Wire throttle body.

MAP Sensor
These engines do not come with a MAP sensor.
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.
Some Ford Performance crate engines do not have any provisions for connecting a MAP sensor to the intake manifold. A fitting will need to be installed in the intake near to the throttle body.
Variable Cams
The Coyote engine has variable cam timing control on all 4x camshafts labelled as Ti-VCT by Ford. This is supported by the Haltech 2500 ECU.
It has a cam position sensor and an oil flow control solenoid for each camshaft. The inlet cam is retarded in its native position and the ECU can advance from there. The exhaust cam is advanced in its native position and the ECU can retard it from there. This is the same as for all conventional variable cam systems.
See the Cam Position Sensor information for wiring of cam sensors. Edge is Falling, Sensor Type is Hall Effect, and Pull Up is Enabled.
The control solenoids require a 12V+ switched power, together with any spare Haltech ECU output. The Stepper Outputs are used for this purpose with our supplied base map to suit the Coyote Terminated Engine Harness. Active State and Drive Type are both set to Low. There are 2x different connectors used for the Coyote engine, referred to as Early and Late.
Idle Control
This engine uses the Drive By Wire Throttle to control idle speed.
Coolant Temperature
Ford refers to these sensors are Cylinder Head Temperature Sensors.
Wiring is not polarity sensitive
| Pin | Haltech Connection |
| 1 | Any Spare AVI* |
| 2 | Signal Ground |
An AVI with a selectable Pullup should be used. If not and external 1k pullup to 5V should be connected.
Air Temp
An Air Temperature Sensor is incorporated in the MAF Sensor. If the MAF Sensor has been deleted and Inlet Air Temperature Sensor should be added.
Knock Sensor
The Coyote engine comes with 2x knock sensors.

4 | Signal Ground |
5 | Knock 1 |

MAF Sensor
Although most users of Haltech ECUs will be deleting the MAF, it is possible to use a MAF if you prefer.
The MAF Sensor is incorporated in the OEM Air FIlter Housing.
| Pin | Description | Haltech Connection |
| 1 | No Connection | --- |
| 2 | Air Temperature Signal | Spare AVI with Pullup |
| 3 | 12V+ Switched | --- |

5 | MAF Signal | Spare AVI |
Alternator
The Coyote engine comes with an Alternator that requires a duty signal from the ECU to control the charging voltage.
Pin | Function | Haltech Connection |
1 | 12V+ Switched | 12V+ Switched (Grey/Red) |
2 | Duty Signal | DPO-3 (Violet/Red) |

O2 Sensors
Adding a Haltech 2-channel Wideband WB2 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. Sensors use a 22mm socket or spanner to remove and replace.
Vehicle Speed Sensor
This engine uses CAN for vehicle speed inputs.
Injector Data
Flow
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: 380cc/min
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.

Base Maps
Base maps have been created for use with the Haltech Elite Terminated Engine Harnesses. These maps come with the ESP Software installation.
