More about our engine and power wiring harnesses
Our harnesses are built here in Livonia and uses aircraft type wire with an insulation of cross-linked, modified ethylene tetrafluoreothylene co-polymer (ETFE).  The insulation resists high PH cleaning fluids, fuels, lubricating oils, and many other chemicals.
The wires can withstand extreme test temperatures, ranging from cold bend at -85°F through to 390°F. These wires are a mechanically tough, flame retardant and weight saving solution to many motorsport and aerospace applications.
The engine harness is fitted with new OEM connectors and terminals for sensors, injectors, coils, ETB, VCT and the oil pressure control valve.  We have changed the harness design compared to the original layout, the Y-split is now located between the two banks at the rear of the engine, between cylinder 4 and 8.
The harness is wrapped using a special automotive high strength and high abrasion resistive polyester tape with acrylic based adhesive.  This tape is rated for temperatures up to 300°F.

Installation of level 2 and level 3 kits:
Installing our control pack is straight forward:
- Fit the adapter for the Bosch pressure and temperature sensor on the intake manifold.
- Fit our new engine harness, it comes complete with original connectors, nothing to modify on the engine.
- Plug the throttle pedal in.
- Plug the included power supply harness into the engine harness power connector.
- Connect the two power supply wires according to the instructions.
- Connect the fuel lines and adjust your fuel pressure to 58 psi.  Use premium gasoline only.
- Connect the headers to the exhaust system.

Your engine is now ready to be started, no calibration or adjustments are required. 
We have done all the hard calibration work.

What to expect performance wise...
All our calibrations are developed to optimize performance, drive ability and fuel economy.  We have spent hours and hours on fine tuning the calibrations we offer for various stages of performance for the Godzilla engine.  One thing to bear in mind when looking at power and torque figures is to look at how the engine was tested.  Typically the engine is tested without the alternator active and without the exhaust system from the vehicle.  We test engines having the original water pump active. 
Furthermore, automotive manufacturers claim their performance data according to the J1349 norm while the motorsport industry uses the J607 norm, also called STP for Standard Temperature and Pressure  This norm specifies different conditions than the automotive norm and therefor the power rating figures are slightly higher than for performance according to J1349.  So, power ratings advertised will therefor be higher than what is originally claimed for the engine.
That said, with our calibration for the standard crate engine we found, in accordance with STP:

Maximum power:     507 hp  @ 5,800 RPM
Maximum torque:    550 lbft @ 4,000 RPM

*BREAKING NEWS*  -  *OBD II*  -  *BREAKING NEWS*  -  *OBD II*  -  *BREAKING NEWS*
Systems and engine harnesses supplied after October 1st 2022 now have a dedicated 16-way standard OBD II connector.  You can plug an OBD II scan tool or an OBD II compliant display module into the connector on our wiring harness to read engine data.
Please note that the engine oil pressure is NOT included in an OBD II data export.  You can use our separate oil pressure sensor kit to add oil pressure to your OBD II compliant display.

OBD II data channels exported from the ECU include these channels:

• Engine RPM
• Manifold air pressure (MAP)
• Mass air flow (MAF)
• Barometric air pressure
• Fuel pressure
• Fuel rail pressure relative to MAP
• Fuel gauge pressure for DI
• Car speed
• Inlet air temperature
• Coolant temperature
• Engine oil temperature
• Throttle position
• Pedal position %
• Lambda value bank 1 (cylinders 1 - 4)
• Lambda value bank 2 (cylinders 5 - 8)
• Fuel correction on bank 1
• Fuel correction on bank 2
• ECU battery voltage
• Ethanol %
• Turbo RPM
• Exhaust temperature bank 1
• Exhaust temperature bank 2
• Transmission actual gear

Data export via CAN:
In addition to the OBD II data export, the ECU also exports 80 data channels via CAN.  With this feature data can be displayed on a CAN based display, exported to a transmission controller or to a data logger.
You can download a document with the specifications from our Support section.

The CAN export is in Big Endian format and the baud rate is 1 Mbit/s.

On-board data recording:
Using the optional communication kit you have access to the ECU's on-board data recording.  The logging capacity is 64 Mb and it can record data from 60+ channels.
The ECU software comes complete with a data analysis software.

Vehicle speed and traction control:
The wiring harness is supplied with an auxiliary input connector.  In this connector you will find inputs for up to 4 wheel speed sensors.  Car speed can be generated from using a single speed sensor triggering off the prop shaft.
If 4 wheel speed sensors are used, one per wheel, a race developed traction control can be activated.

Drag race control and launch control:
A section in the ECU software includes launch control and drag race features.  The system will handle a two-step limiter, the transmission lock.
You can control these engine parameters as function of the drag timer.  The drag timer starts running the moment you let go of the trans lock switch:

• Target boost pressure
• Actual throttle position
• Spark advance offset
• Engine RPM limiter
• Nitrous control

Gear shift control for manual transmissions:
The software includes a gear shift strategy for use with manual race type transmissions.  The strategy includes individual shift settings for each gear for both up and down shift.

Automatic transmission controller:
A stand alone controller is required if an automatic transmission is used.  The engine wiring harness has a connector for such a controller, providing connections to:
- Power and ground
- Engine RPM and load
- CAN data export (used by some manufacturers for engine data)

Connection to instrument cluster:
Our ECU can send data via CAN to almost any instrument cluster which have a CAN link for importing data.
We are building a database for instrument clusters for which we have confirmed they will function with our ECU.  Please contact us if you are in doubt whether your cluster is able to import data via CAN and how to set it up.

Where to purchase our Godzilla control pack:
Our kit is supplied through selected specialist dealers across the country, these tuning shops can access E8G's software features.
So if you are thinking about modifying your engine, for example by fitting a high performance camshaft, fitting a supercharger or going for a turbo solution, our kit is easily updated to accept such changes.  Ask us about these performance updates.

Dealer inquiries are welcome.

OBR development work:
We keep on developing kits and improving current kits.

Coolant Plug Kit
Our coolant plug kit is required to block off the coolant outlet in the block on the driver side by the flywheel. 
If you do not require a heater in your vehicle you can use a second coolant plug to block off one of the coolant pipes for the heater.  This pipe is located in the front of the block, next to the thermostat housing.

Ford Drive-By-Wire Pedal Kit
This kit is a direct plug in for use with our control pack.  Supplied with connection cable.

Wide Band Lambda Sensors
By adding one or (preferably) two wide band lambda (O2) sensors to your control pack the system monitors, regulates and learns the optimum fuel injection.
This is perfect way to ensure your engine always runs at its optimum calibration.

Calibration Upgrade Kit - High Flow Fuel Injectors & 3 bar MAP sensor
If you are planning to build a high performance engine with power exceeding 570 hp you will have to consider replacing the standard fuel injectors.  These new injectors flow a lot more fuel, rated at 67 lb/hr @ 58 psi fuel pressure.  They are a direct replacement of the standard injectors, same length and same connector.  These injectors flow enough gasoline to reach up to 1,000 hp with the right fuel pressure.  Using E85, there should be enough flow to reach over 700 hp.

The injectors can be supplied as a kit with a manifold air pressure and air temperature sensor, having a 3 bar absolute pressure range.  This sensor directly replaces the 1 bar absolute air pressure sensor supplied with our standard control pack.  No modifications to the control pack engine wiring harness is required.
This upgrade kit also includes a modified calibration for use with these injectors and the 3 bar MAP sensor.

Fuel Pressure Sensor Kit
150 psi stainless steel fuel pressure sensor kit complete with adapter cable plugs straight into the OBR engine harness.  No re-calibration is required, the control pack is configured for use with this sensor kit.
The sensor has a 1/8-27 NPT male thread, compatible with most pressure regulator blocks.

Oil Pressure Sensor Kit for use with OBD II display module
The engine oil pressure information is NOT included in the OBD II data from the ECU.  This kit is supplied with a 150 psi stainless steel oil pressure sensor, an adapter between the engine and the OEM oil pressure sensor plus a connection cable.  With this kit connected to an OBD II module you can keep an eye on oil pressure.
Specifications:    0.5 Volts =     0 psi
                             4.5 Volts = 150 psi

Manifold Air Pressure (MAP) Sensor for Supercharged and Turbo Engines
45 psi absolute air pressure and temperature sensor plugs straight into the OBR engine harness.  To use this sensor a re-calibration of the control pack is required, please contact us for assistance.
