In the case of a higher redline, the engine may very well be capable of performing at a higher engine speed, though this also means higher levels of wear and a far higher risk of catastrophic engine failure if pushed too far. Should this detonation occur, the knock sensor may not be able pull out enough timing to protect the engine. If tuned improperly, it can cause immediate and serious engine damage.Īdvancing timing can mean more power but also a higher chance of potential detonation. Leaner fuel maps mean more power but are far more vulnerable to a bad tank of gas or higher air temperatures. The problem from the factory’s point of view is that changes to the ECU tuning all have a potentially negative impact on reliability. Some of this damage may be irreparable and to the engine. Interfering with the systems that it operates by accidentally adjusting some of the settings on the chip or by tampering it without knowing exactly what you’re doing can cause your vehicle to lose performance quality and even to break down entirely.
In most cases, it is best to leave the handling of the chip to professionals. It is accessed through a port called the diagnostic port.
The ECU in your vehicle is typically located within the dashboard controls. The chip responds to stimuli from the vehicle in order to boost pressure to the valves and fuel injection systems, to regulate the top speed and acceleration of the vehicle, and more. All of these are crucial to the functioning of your vehicle. Among these are the automatic transmissions system, the vehicle stabilization system, the fuel injection, the valve support systems, the timing and ignition systems, and the speed governance system. Systems the Chip Controlsĭepending on your car type and year, the ECU may control a wide variety of different systems. The chip in your vehicle controls a number of different systems, regulating and ensuring they’re properly powered at all times. The cost of this can depend on how you have it done.Īn engine tuning chip is a crucial part of your car’s electrical and computer systems. When you reprogram this, you can tell the chip what you want to happen with this mixture. The ECU chip is located in the injection system and regulates the amount of air and fuel mixture that takes place. Engine chip tuning is a process where the electronic control unit is reprogrammed, making the engine work within different parameters.
