OBR Ford Mustang 2.3L 4V TiVCT GTDi Control Pack - Coming Soon

OBR has put together a new Stage 1 engine control pack for Ford's 2.3l 4-cylinder turbo charged Mustang engine. Our aim is to supply our customers with a well engineered and easy to install kit, offering very good drive-ability straight out of the box.  With this kit the engine has a wide torque band with significant power increase.  No calibration is required by the customer, it is aimed at being a plug-&-play solution.
This kit includes our new OBR E5RS controller and a bespoke OBR engine wiring harness (build using aircraft style high quality wire).
All standard sensors, actuators and drive-by-wire throttle body are used, no exchange of parts is required.

An even higher performance Stage 2 version is also in development. Check this space....

What the base kit includes....

Our kit for the 2.3L 4-cylinder engine is based on our E5RS ECU.  This controller is specially configured to control ALL standard features on the Ford engine, you do NOT have to change or modify any sensor or actuator on the engine.

Our base crate engine kit includes these parts:
- OBR E5RS stand alone engine controller - ONE single module to control your engine, traction control and race transmission!
- New OBR high quality engine wiring harness for our E5RS controller and with standard Ford connectors for all sensors, actuators, coils and injectors.
- Power supply cable with main relay and fuse plus connections for fuel pump relay, fan relay and tach.
- E5RS gasoline calibration for the standard Mustang crate engine using standard fuel injectors, ignition coils, throttle body and all sensors.  Loads of power and torque.

This kit controls all standard sensors, coils and actuators:
- The standard drive-by-wire throttle body, reading its data stream directly.
- Variable camshaft timing in closed loop.
- Standard ignition coils.
- Works with standard base model turbo charger.

Installing our control pack is straight forward:
- 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 feed fuel pressure to 58 psi.  Use premium gasoline only.
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 2.3 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 then 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:     348 hp  @ 5,500 RPM
Maximum torque:    389 lbft @ 3,500 RPM

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.

We are working on an update of the software which will add a true OBD II port to the system. 
With this option you can plug any OBD II scan tool into the connector on our wiring harness to read engine data. 
You will also be able to connect a stand alone display module which is prepared for OBD II communication.

Where to purchase our 2.3L 4-cylinder TiVCT GTDi control pack:
Our kit is supplied through selected specialist dealers across the country, these tuning shops can access E5RS'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.
