OBR Ford 7.3 V8 'Godzilla' Control Pack - supports early engine version up to and including 2022.

Our kits for the early 'Godzilla' engine are based on our Euro-8+ ECU.  This controller is specially configured to control standard features on the Ford engine, you do NOT have to change or modify any sensor or actuator on the engine.

Important Notice
Our control packs are calibrated using premium fuel with 93 octane rating with fuel pressure set to 60 psi.

• It is essential that you use this fuel grade.
• Using a fuel with lesser octane rating may result in severe engine damages

Please contact us if this fuel grade is not available in your area and we will provide you with a 87 octane calibration.  
If you are using our calibration tool OB256, you can of course adjust the spark advance to whatever you choose.

Engine Computer
The Euro-8+ ECU is designed and built in Italy, originally as an OEM system for a well know sportscar manufacturer but updated to include on-board data recording and offers full sequential control mode for a Godzilla engine - even with staged injection controlling 16 injectors.  It has most control features expected to be found in an OEM system, including the ability to handle flex fuel control.

Engine Wiring Harness
Our harnesses are built here in Livonia (Michigan) and uses high tech aircraft type wire with an insulation of cross-linked, modified ethylene tetrafluoroethylene co-polymer (ETFE). 
The wire is insulated with modified radiation cross-linked ETFE polymer.  It has a temperature rating of -65°C to 200°C [-85°F to 392°F] continuous using a silver plated copper conductor, and combines the easy handling of a flexible wire with excellent scrape abrasion and cut-through characteristics.
The insulation resists high PH cleaning fluids, fuels, lubricating oils, and many other chemicals.
These wires are a mechanically tough, flame retardant and weight saving solution to many motorsport and aerospace applications. 
Due to the quality of the advanced insulation used the wire is lightweight and very thin.
For example, our 22 gauge wire has an outer diameter of only 0.043" (1.09 mm) and the 20 gauge wire has a diameter of only 0.050" (1.27 mm).  This makes our harnesses lightweight, compact and very robust.  Combined with the excellent fitness on the engine, we supply the top product for the engine.
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 connection to the ECU from the back of the engine is long enough for the ECU to be fitted in the cabin - but it can of course also be fitted in the engine compartment.
The harness is wrapped using a special automotive high strength and high abrasion polyester tape with acrylic based adhesive.  This tape is rated for temperatures up to 300°F.

Power Wiring Harness
The power supply harness is included in the kit and is made using the same high tech wire and tape as used for our engine harness.
It is fitted with 3 relays, one for the engine control, a second for the fuel pump and the third is a spare, for example for a fan.  All relays are fitted with a 30A fuse.

TMAP Sensor and Fitting Adapter
Our control pack reads the manifold vacuum and uses this data as an expression for the engine load.
A sensor measuring the absolute pressure in the intake manifold is included in the kit.  No drilling is required.

Which Throttle Bodies are Supported?
Our system supports almost every single type of throttle body, you can find on the market.
Generally, supported throttle bodies are divided into 3 main groups:
- Operated by a throttle cable and fitted with an analog position sensor.
- Drive-by-wire throttle body with an analog position sensor.
- Drive-by-wire throttle body fitted with a digital SENT style position sensor.

Control Pack
We have changed the way we supply calibrations with our kits.  Initially, there were not that many performance parts available But today there are so many different parts on the market, numerous different intakes, throttle bodies, camshafts etc.
The changes between our kits using different performance parts are with the ECU tune and it can be configured to handle almost any configuration, being naturally aspirated, turbo charged or supercharged engines.

- Connect the fuel lines and adjust your fuel pressure to 58 to 60 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 LS engines.  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 with the alternator active, water pump connected and in use but without the exhaust system from the vehicle.
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:     500 hp  @ 5,800 RPM
Maximum torque:    560 lbft @ 4,000 RPM

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 Euro-8+ ECU software includes launch control and drag race features.
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:
Euro-8+ has a dedicated power shaft and paddle shift gear shift control for use with manual race type transmissions. The closed loop strategy has 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 ECUs can send data via CAN to almost any instrument cluster which have a CAN or OBD II link for importing data.

Where to purchase our Godzilla control pack:
Our kit is supplied through selected specialist dealers across the country, these tuning shops can access the ECUs 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.

We finished mapping our 2023 Godzilla engine fitted with the new camshaft from Willis Performance / BTR, the Ford Performance intake manifold with a 92 mm throttle body. We ran 2 different tests, one using the standard cast iron headers and the second using long tube dyno headers manufactured by McLaren Performance Technology.

Power speaks for itself - 626 hp @ 5,750 RPM and 644 lb.ft @4,600 RPM.
Look at the available torque, it is above 590 lb.ft from 2,600 to 5,800 RPM:

We recently tested our engine with the the InnoV8 intake system with 8 individual throttle bodies and drive-by-wire throttle control.  We fitted it to our engine which is also having the BTR 'Truck Norris' camshaft.
Furthermore, we are using a set of headers, made by McLaren Performance Technology, and the result was very impressive.  The engine develops now 655 hp @ 6,000 RPM and has 624 lb.ft of torque @ 4,500 to 5,000 RPM.  And all this is obtained with the standard fuel injectors at 72 psi of fuel pressure.

We tested an almost standard engine fitted with a Harrop supercharger and our kit #4.  The engine was fitted with forged Mahle pistons, our spark plug cables and NGK spark plugs, otherwise standard.
We also used new, beautifully made fuel rails supplied by Indy Power Products.

The performance is outstanding!  With 7 psi of boost, the engine developed 766 hp and 757 lb.ft - with 700 lb.ft+ from 2,500 RPM, according to STP norm.

The performance, we achieved is astonishing.
At 2,500 RPM the engine has 700 lb.ft. and at 6,000 RPM the maximum power reached is 766 hp.
Look at an impressive power curve for this engine:

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.

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 Rail Connector
Only use the right type of connector for the special connection on the fuel rail.
OBR can supply an aluminum fitting – OB092 - with quick connect to the original fuel rail and a -6 AN male connection to the fuel line.

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.
