Thus the ecu in order to make accurate diagnosis on engine control utilizes stored data. This is a short video that will show you which tools is required for ecu rempping.

However keep in mind that different tuning companies have different maps and you should go with a reputable company.

Remapping ecu yourself. The cost of remapping a car varies between different tuning companies. The remapping until recently was done by removing the existing chip containing the software. Diesel and petrol engines work a bit differently but that isn t really important right now.

This system is run by the brain of the engine the ecu engine control unit. A remap is changing the manufacturer s engine map to a custom setup of your own. The ecu tells your engine not only what to do but also how to do it.

There is an open source ecu remapping project out there where people upload and swap files. So ecu remapping can be done by just over writing the existing software program of your car and replacing it with a more tuned software best fitting your conditions. If low quality fuel is present the ecu can adjust the mixture of fuel and air to prevent engine damage.

The ecu also controls the boost of the turbo if you have one. The ecu shuffles through the tons of data that come to it in the form of readings to decide the course of action that should be taken by the engine to ensure an ideal drive. When you put your foot down the ecu decides how much fuel and air to mix squirt into the cylinder and ignite.

A word of caution though getting it wrong can literally destroy your engine the maps are fairly complex 3 dimensional affairs and it is a lot more complex than just hacking in and changing a few numbers around. For example the manufacturer map may include a fuel quality adjustment for safety purposes. There is a good way and a bad way to tune a car.

The stage 1 ecu remap could cost anywhere between 300 to 800.
