There is also real risk of damage to fragile electronic ECU components during this operation. All these events lead to potential danger of engine malfunction or even its destruction. An addition, to allow overwriting, ECU safety systems are blocked during remapping. Remapping drawbacksĬopied to the ECU fresh handling programs as a usual do not pass such strict testing procedures as standard protocols.
In some cases, newly written or deeply revised programs, which were recorded into ECU memory, can radically raise engine productivity to the level, which can’t be achieved by chip-box tools. The manipulation is very alluring due potential ability of maximum speed limit cancellation or modification. Vehicle ECU is connected to laptop through ODB connection (specific type of data transferring cable) and stock operating protocols are replaced with new designed ones.
Only highly educated specialists are able to implement this procedure properly. Modification of the data in directly in the ECU – remapping. It also does not violate warranty conditions because it leaves main operating protocols intact. The possibility of engine destruction due to this way of chip-tuning is unreal. It neither can’t be tracked by car protection programs, so you won’t see “Check Engine” indicator with its annoying yellow light. Supplementary device does not affect any byte in the memory of main control unit. As a result power and torque output grows. The additional unit modifies signals, which sensor supply to the ECU, and in definite situations can substitute handling impulses form ECU to different engine systems. It can be provided just in everyone’s garage. It is quite simple manipulation, which does not require any special education in the field of electronic. This procedure is also known as “remapping” Supplementary electronic device mount Modification of the data in directly in the ECU. There are two different approaches to chip-tuning procedure: As a result, motor power output can be increased or fuel economy can be obtained, according to the needs of vehicle owner. The main issue of chip-tuning is to boost engine potential without any intervention to its mechanical parts but only by modification of handling impulses from electronic control unit. As a rule, the most trustworthy data about chip-tuning is reported by specialized tuning firms.
