These devices generally plug into the diagnostic port although in some cases the reprogramming is done directly on the circuit board. The most common way to ‘upgrade’ the ECU is using either plug in modules as mentioned above or using a special tuner device who will use an OBD / BDM /Jtag tool. They are like artists with different philosophies, tools, approaches and abilities.
#ECU TUNING BASICS CODE#
It has a lot to do with the type of car, level of modification, familiarity with the code and the market the tuner is trying to target.
#ECU TUNING BASICS PROFESSIONAL#
Without re-mapping the fuel tables, some of the performance gains from the modifications may not be realized.Ī good tuned ECU can result in increased performance, drive ability, and never cause engine damage, that’s why your choice of your tuner has to be more then precise and only go to professional peoples with a good knowlage in Electronics and Mechanical!Ĭhip tuners will take a whole spectrum of approaches to retuning your car for additional power. These “bolt-on” modifications alter the way that the engine flows, often causing the air to fuel ratio to change. Most manufacturers tune for optimum emissions and reliable engine duration under any condition with purposes which can limit performance.Ĭars with a turbo fitted can have the requested and allowable boost levels raised these applications usually have the most effect if the turbo fitted is a low pressure turbo which leaves the most room for improvement.Īnother reason to change the ECU map is if there are engine, intake, or exhaust modifications to the car. In addition, changing fuel maps to coincide with the best ratio for gasoline combustion may also realize performance increase. Manufacturers design for a lower specific timing and bad fuel quality, this may limit performance accordingly. However, to cope with advanced timing, one must run high-octane gasoline to avoid pre-ignition detonation or pinging. Higher timing may result in higher performance. Performance gains are realized by adjusting the ignition timing advance. That’s why we can’t use chips available from European tuners such as Alpina or AC Schnitzer. market ECUs are very different since the two markets have different emissions regulations and fuel grades.

There are myriad ECU configurations out there some differences are even based on where the car is sold.

#ECU TUNING BASICS SOFTWARE#
This means the ECU software and engine management algorithm would be different.
#ECU TUNING BASICS SERIES#
As an example, one model year of the 3 Series might use an intake air temperature (IAT) sensor in the intake manifold while other model years use an integrated mass air flow (MAF) and IAT sensor. Model year differences and sometimes option levels might also require different software calibrations and setup. Between the car manufacturer and supplier, each system is custom designed and the software calibrated for each vehicle. All the vehicle’s sensors required to run the engine, transmission, diagnostics, ABS, traction control, airbags and even security are also supplied with the integrated system. The primary part of these EMS systems is the electronic brain, called the ECU. These are complete electronics packages including the engine and transmission control units and any additional modules. The ECU in a modern automobile, together with advanced engine technology, makes it possible to control many aspects of the engine’s operation, such as spark timing and fuel injection, Throttle, Valve timing, Valve lift, and many others parameters.Ĭarmakers go to suppliers such as Bosch, Seimens, Motorola and Magneti Marelli for engine management systems (EMS). The Electronic Control Unit (ECU)ĮCUs are a relatively recent addition to the automobile, having first appeared in the late 1980s.As technology advanced, so did the electronics that go into cars.

Modern ECUs can be tuned by simply updating their software.
#ECU TUNING BASICS SOFTWARE UPGRADE#
Chances are, a “chip” for your modern car is nothing more than a software upgrade that’s reflashed onto your ECU’s memory via the onboard diagnostic (OBD-II) port. The days of manually pulling and replacing EPROM chips from a factory ECU are long over. Chip tuning refers to changing or modifying an EPROM chip in a car’s or other vehicle’s electronic control unit (ECU) to achieve better performance, whether it be more power, cleaner emissions, or better fuel economy.
