Flash tuning can be carried out with a handheld OBDII device or a laptop with adequate software.The user-friendly interface of TOAD Pro makes it accessible to tuning beginners, while its robust advanced features give experienced professionals lots of options to work with. Often, they include data logging and monitoring features. These can be a straightforward way to increase horsepower, raise RPM limits and improve power delivery. Most of these devices can be used to modify individual parameters, and many are offered with presets to expedite the process. Piggyback ECUs can be significantly cheaper than stand-alone modules, but have significant limitations.įlash tuning is a method that involves reprogramming the ECU chip. These devices aren’t able to read or modify other critical values, making them the most basic form of tuning. Piggyback devices can only create false sensor data, modifying signals from the O2, lambda, fuel rail, and MAP sensors. These devices essentially modify the sensor signals being sent to the ECU, resulting in altered feedback. The most basic tier of ECU tuning is to use piggyback tuners or tuning boxes. Some of these include EGR (Exhaust Gas Recirculation) valves, EVAP (Evaporative Emissions Control), VTEC (Variable Valve Control) and, in diesel engines, DPF (Diesel Particulate Filters). This electronic method works similar to the mechanical action of a choke fitted to a carburetor.Įmissions regulations have resulted in a number of systems that also fall within the authority of the ECU. The ECU manages the air-fuel mixture by collecting data on air and fuel temperatures, air pressure, and overall demand. While some ECUs can be relatively easy to tune, many modern systems are heavily encrypted and require some degree of complexity. It also manages turbo and superchargers and maintains functionality in hybrid configurations. The ECU controls parameters such as air-fuel ratio, RPM limits, and ignition timing. The ECU is sometimes referred to as an ECM (Engine Control Module) or DME (Digital Motor Electronics). Through the 2000s to today, the ECU has adopted heavy responsibility in controlling throttle response, emissions systems, and fuel management. Once fuel injection was introduced in the 1980s, engine control units became more sophisticated in terms of fuel management and lambda control.
In the 1970s, basic versions of the ECU were used to optimize carburetor solenoids and, at a basic level, controlled the air-fuel mixture at idle.
