Ford 7.3 V8 'Godzilla' 2023 Version Crate Engine Control Packs - updated 05.01.2024

Our kits for the 2023 7.3 V8 'Godzilla' engine are based on our E8G 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.

Engine Computer
The E8G 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 if the engine has 16 injectors.  It is used for both the early engine version as well as for the current version, from 2023.  It has most control features expected to find 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 as is an adapter used to fit it onto the intake manifold.  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 only real changes between kits using different performance parts are in the ECU tune.  The only real difference in hardware requirements are with kits for turbo charged or supercharged engines.  These engine require new high flow fuel injectors and a 3 bar TMAP sensor.

Which Kit To Order:
Give us a call to talk about your planned engine program.
To help making us pick the right engine tune, we will need to know for example which intake manifold, which type and model of throttle body and which camshaft you want to use.
Please note that depending on your chosen parts, the ECU tune might need a minor correction.  This is typically an easy fix since you can have full access to the ECU tune.
This can be handled in 2 different ways:
- Rent the tool for a week and correct the ECU tune with our support.
- Purchase the communication kit OB256 and you will have full access to ALL ECU parameters.  You can completely re-calibrate the ECU to suit any engine and any engine state of tune.

Does OBR Offer Any After Sales Support?
Yes, OBR has an excellent after sales service.
For a period of 12 month from your purchase, you are free to contact us by phone and by email with questions or comments about the kit, this is included with your purchase of the kit.

If your ECU tune requires adjustment, the OBR support for this is a one-time service and is also included with your purchase.  To do this you must have the OB256 kit.  You can either rent or purchase this communication kit.
If you decide to rent the kit, we charge $100 plus shipping for a 5-day term. 
If you decide to purchase the kit, the cost is $544.  If you earlier did rent a kit, we will deduct the rental cost you spent from your purchase of the kit.

If you want to have OBR support during a complete remapping session of an engine, we will charge our normal engineering support charge per hour.

Installation of our kits:
Installing our control pack is straight forward:
- Fit the adapter for the TMAP 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 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 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:     500 hp  @ 5,800 RPM
Maximum torque:    560 lbft @ 4,000 RPM

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.
Lately, we calibrated a 7.3 engine fitted with Brian Wolfe's stage 1 camshaft and an INNOV8 intake manifold with 8 individual runners for each cylinder. Power reached 610+ hp....

Our 2023 engine going on the dyno for calibration and performance testing.

After installation we ran a quick check on our calibration and did several power runs.

Power speaks for itself:

This test is the same engine specifications but this time we ran it with our Godzilla dyno long tube headers, a very impressive result considering this is with very simple and affordable engine modifications:

Note the power - 626 HP @ 5,750 RPM and that impressive torque of 643 lb.ft @ 4,400 RPM.

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.

Kit options include:
- Coolant plug kit.
- Ford drive-by-wire throttle pedal with wiring.
- Optional closed loop fuel control by adding 2 x wide band lambda sensors to the kit.
- Alternator fitting kit.
- Power supply harness with relays for power, fuel pump and coolant fan.
- Shift controller for 6R80 automatic transmission.
- Fuel pressure sensor.
- Upgrade kit with injectors, new TMAP sensor plus upgraded calibration for boosted engines.

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.

NGK Racing Spark Plugs
We now offer NGK Racing spark plugs for modified engines.
Two versions are currently available, one with heat range 8 and one with heat range 9.
The standard plug is heat range 7.
These spark plugs fits the standard cylinder heads.

High Performance Plug Wires
OBR offers high performance and high quality plug wires.  They are made with thick black silicone cable covered fiberglass sleeve, heat resistant to in excess of 1,000 deg F.  Coil and plug boots are made with ultra high temperature 45 degree boots with high temperature silicone tape on the spark plug boot.  Tabs are stainless steel with a very positive feeling when connected.
Highly recommended on a high performance engine.

Plug Wire Heat Insulation Socks
The heat insulation heat protection socks have an impressive double-layered fiberglass design that will add extra protection to exposed spark plug boots and wires. These socks will protect spark plug boots and wires from header and exhaust manifold high temperatures. The plug wire socks also provide an easily visible way to detect potential burn areas before they occur. They are soft and very flexible, easy to handle and install and will adapt to stretch easily over irregular surfaces.

All relays are supplied with a 30A built-in fuse.
This harness is included with control pack kits level 2, 3 and 4.

Automatic Transmission Shift Controller
If you are using a manual transmission, our control pack will work perfectly with your engine and transmission.

To control an automatic transmission a separate stand alone shift controller is required.
There are several options on the market and we shall be happy to direct you to manufacturers, we are working with.  Any of these controllers connects directly to our engine harness and secures a trouble-free installation.

Wide Band Lambda Sensor Kit for Engine Development
For engine development work, where the combustion in each individual cylinder must be monitored, please see our kit OB401.  The ECU in our control pack can import lambda data from additional sensors via CAN, up to 8 sensors can be added to the system, one for each cylinder.
The 2 main lambda sensors used for fuel control and self mapping connects directly to the ECU.

The control pack for use with a supercharged 7.3 V8 'Godzilla' engine is based on our E8G ECU, programmed with a tune specifically for this kind of engine performance.  As with the standard control pack, this ECU is specially configured to control standard features on the crate engine, you do NOT have to change or modify any sensor or actuator on the engine.

Our 'Supercharger" kit includes these parts:
- OBR E8G stand alone engine controller - ONE single module to control your engine!
- New OBR high quality engine wiring harness for our E8G controller and with standard Ford connectors for sensors, actuators, coils and injectors.
