WHAT IS EDC-16 INJECTION SYSTEMS?

Electronic Diesel Control (EDC-16) is an electronic engine-management system for diesel engines. Bosch presented the first system of this kind for passenger cars in 1986. Since 1989 it has also been used in commercial vehicles, where it has now become part of today’s standard equipment. EDC-16 combines all control and regulation functions in one electronic engine control unit to which the injection system and a large number of sensors and actuators are connected.

Bosch Electronic Diesel Control ensures ideal diesel injection control at all engine operating points. It evaluates in real time sensor data on the temperatures of coolant, fuel and charge air as well as the momentary engine speed, the position of the accelerator pedal and the intake air mass. From these values the EDC-16 calculates the best possible injection process and the correct amount of fuel to be injected.

The new Electronic Diesel Control EDC-16 engine management system from Bosch has its debut in the V10-TDI- and R5-TDI-engines. Bosch EDC-16 engine management system is designed to be compatible as both a single and double control unit concept. The actual concept used depends on the number of cylinders in the engine.

WHAT IS BOSCH EDC-16 REMAP?

When a manufacturer develops a new car they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions. These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions.

ECU remapping is taking a read from the ECU’s processing chip of the vehicles standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.

WHAT DO YOU ACTUALLY MODIFY IN MY VEHICLE?

We do not change any hardware in your vehicle, we just modify the operating parameters in the ECU’s program or ‘map’. In many cases the map stored on the ECU’s processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. In some newer models the ECU will have to be removed from the vehicle and the casing opened, our technicians will then use specialist tools to read the original map straight from the processing chip.

The technician will then upload the original map to our map writing team who will adjust the parameters to maximise the performance, fuel economy or a clever blend of both. Depending on the vehicle and ECU type the chip tuning process can take under an hour and if at any time you wish to return your vehicles ECU to its original default settings, this can be done easily and free of charge as we always keep a copy of the original software as a backup.

SAVING FUEL WITH BOSCH EDC-16 REMAP?

When we remap a vehicle, especially when fuel saving is the priority we focus on improving the low end torque in particular and widening the power-band as far as we can.

This increase in low end torque will mean less throttle pedal input is required to maintain cruising speeds, when fully laden or when on a gradient. It will also mean that the vehicle will be more comfortable in higher gears at slower speeds as well requiring fewer gear changes overall.

If you combine these factors with adjusting your driving style to make the most of the extra low end torque you will see an improvement in fuel consumption. This is most effective on turbo-diesel engines where the savings could be as much as 20%!
