Remapping Details

Just as a brain controls the human body, a unit controls engine operation in vehicles. This is called ECU (Engine Control Unit). ECU has a software thats manages this operating system and this software includes hundreds of maps which each of them has different mission. Tuning companies re-optimise the maps for reaching results targeted. This all process is called ECU remapping

ECU remapping process has 3 steps, these are reading pre-existing software from ECU, developing a new software by re-optimising related maps and writing new software back to ECU. For reading and writing operation, an interface tool is used with different connection types. This tool provides both to download a copy of pre-existing software from ECU to your computer and to re-write new software from your computer to the ECU. Developing new software is done by professional specialists. They use different kinds of editor programmes to edit software

An interface tool can be connected ECU in 3 different types. First is OBD (on-board diagnositcs), second is bench mode and third is bootloader mode. OBD is easiest way because you don't need to take ECU off to be connected. At the same time this mode shorten the period of operation. But bench and bootloader ways take longer time because the ecu must be removed, even the top case of ecu must be opened in bootloader mode. For learning more, please visit blog section and find all detail descriptions of connection types out

There are three connection types (OBD, Bench and Bootloader) for reading and writing. Operation time depends on connection type for the vehicle. OBD (on-board diagnostic) connection is easier than others and takes shorter time. Bench and bootloader types requires to remove the ecu so take more time. But averagely, the operation takes 1.5 - 3 hours.
