Modern motor vehicles and bikes are being manufactured with the ECU (Engine Control Unit). This is a programmable device that receives and analyses information from various sensors around the engine. Such information includes the oxygen content during fuel combustion, current accelerator pedal angle, engine temperature among other parameters. The ECU then interprets the information and sends a feedback to the sensors in order to take corrective action or optimize a certain process. Since cars, trucks and bikes are manufactured for different environments, their ECUs are normally uniquely programmed to meet certain standards. The act of readjusting the vehicle’s ECU program to meet specific standards of its environment is referred to as remapping and thus the term, ECU remapping.
Vehicles that should Be Remapped, The Hidden Costs and The Drawbacks
Despite the fact that most modern vehicles and bikes have ECU remapping devices, there are some which are manufactured without. Such vehicles, turbo models, those that inject fuel electronically, TorqueCars and those fitted with additional performance parts should be fitted with ECUs or have their ECUs remapped for better performance. However, this improvement comes at a higher cost due to the need to service the vehicle more frequently and at shorter intervals, one is also restricted to high quality fuels and the need to replace non-performing components due to the resulting extra work. Additionally, the engine experiences more stress as a result of the greater power produced and this may cause rapid failure of sensors and increased wearing of pistons, bearings and clutches.
Specific Benefits of ECU Remapping
In general, this device was designed to increase the engine’s power while boosting its torque. Furthermore, it reduces the throttle response time while widening the power-band. These performance features improve the flexibility of the engine while generating a livelier drive. Notably, ECU remapping has specific benefits for different types of engines. To begin with, the turbocharged diesel engines will experience better torque, increased horsepower, safe overtaking due to improved throttle response and most importantly, better fuel economy.
Turbocharged and Non-Turbocharges Petrol Engines
Petrol engines with turbocharged features are highly recommended as sports flagship engines due to their better power and torque compared to the non-turbocharged petrol engines. When remapped, they perform even better since the ECU reduces wastages by controlling the pressure control of the turbo boost. Other benefits due to ECU remapping include: more horsepower and torque, quicker throttle response, safe overtaking and most importantly, a smoother delivery of power. For non-turbocharged petrol engines, remapping increases the engine power by 8-15% while further improvements cause the exhausts gases to flow freer, air-filters allow high flow and better utilization of re-profiled camshafts.
Legality, Saving and Actual Modification
ECU remapping is legal. However, the insurance company should be notified of these modifications. When performing this modification, the fuel saving property is achieved by ensuring just a little pedal input is exerted to maintain moving speeds. The modifications done always targets the ECU’s program (map) accessed through an ODB (On-board diagnostics) port. In most cases it is normally located on the underlying surface of the dashboard.
