Have you heard of aftermarket ECU

You may didn’t hear of aftermarket ECU, but don’t worry, i have collected some information to help you. First, please allow me to introduce to you the definition and introduction of it.

The ECU ( electronic or engine control unit) controls many aspects of the modern engine. It takes readings like the intake air temperature and mass, amount of oxygen in the exhaust, engine load, rpm and other factors to calculate the optimum duration and timing of the spark and amount of fuel needed.

Manufacturers are fairly conservative in setting up to make the car run reliably under harsh conditions. These unfavorable conditions range from poor fuel to missing maintenance intervals and are generally overlooked. It is worth noting that two identical engines are rare. 20% difference in power has been noticed on the same engine in the plant!

We have seen that this should essentially be a huge difference between the power output and the curve of the same block, highlighting the need for a hard job for manufacturers of all ECU.

For this reason alone, there is a good reason to improve and tighten the timing. When you add other tuning components and other modifications to the mix, upgrading the ECU becomes critical.

Some modern ECU have a degree of self-learning capability and adjust fueling and timing based on the data read over a reasonable distance. This is better than a fixed set of parameters, but still needs improvement, especially if you make other changes.

Unfortunately, ECU need to be reprogrammed, although some engines are too old. Even if some engine ECU are protected or locked, they can not be changed.

One answer is to add an aftermarket ECU. This effectively replaces the car's standard ECU and allows users to write customized fuel and time charts. Turbo engines are even more advantageous when used in conjunction with electronically controlled step-up controllers.

Do not confuse the aftermarket ECU with a knuckle-mounted ECU or plug-in case. We are discussing a complete engine management system that is suitable for adding to older hydrocarbon engines converted to fuel injection and also for upgrading vehicles with non-remappable ECU (mostly manufactured before 2001).

There are a lot of benefits. A standard NASP engine can see a power gain of up to 10%, and you can realize these potentials if you add other changes. The turbocharged engine gains even more, at around 30% extra power, and even more mod There are many types of after-market electronic control units. The basic electronic control unit controls the fueling and timing of the 4-cylinder engine. More sophisticated is the V8 management, faster processing and finer control. A good example of how to get the best out of these settings is that you should use a rolling road. This allows you to see what the engine is doing at any time and easily diagnose lean or rich health and other potential problems.

If your ECU is set incorrectly, it is easy to damage your engine. Wrong sparks, excessive fueling or other problems can literally rip an engine. The immobilizer and other settings on some cars (windows, air conditioning, and even some car gearboxes) are also controlled by the ECU so in some cases you may need to bypass these devices or find a way to keep the car standard ECU Pleased, while aftermarket and engine management actually work.
