We’ll be adding more content and articles in the next few weeks.With ECM Titanium 2.0, Alientech team has brought several important improvements that will simplify your work! A new file matching system, that will be constantly extended and updated, has been created and a new structure dedicated to drivers that enables to increase the maximum number of maps contained has been introduced.

We have a series of how to remap videos on YouTube. In reality the process is more complex, but hopefully this helps to explain. It could move to a meaningless part of the ECU map and add enough 1s to pass the checksum verification. Tuning software with checksum checking can “pad” the file with the neccesary bits so that it passes the checksum test. If it does not, there is an error and the car may not start. For example if a normal file has exactly one million 1s present the car can check the current remap to see if it also has one million 1s. To illustrate we could imagine a tuned remap file and sum up all the 1 and 0 bits in the binary file.

It’s a mathematical check to make sure the map is not corrupt. Manufacturers use a checksum process to make sure the ECU map has not been tampered with.

Software packages like WinOLS and ECM Titanium provide this and you can also find free remapping software such as VAGsuite. A remap must change the contents, but since none of us speak the binary language of computers we need some software or an application to translate for us. The ECU map is stored in digital format on the memory of the ECU. They may be a good way to learn without spending a lot of money if you’re happy taking on the risk of the remap going wrong. These may be illegal if they violate intellectual property, and they also may be unreliable. There are clone tools available from ebay or independant websites. There are excellent flash and read tools such as Amtech MPPS, Alientech KESS/K-TAG, Dimsport Genius, and FGTech Galletto. Official and genuine cables are expensive but more reliable and better supported.

If low quality fuel is present the ECU can adjust the mixture of fuel and air to prevent engine damage. A remap is changing the manufacturer’s engine “map” to a custom setup of your own.įor example the manufacturer map may include a fuel quality adjustment for safety purposes. Too much air and the mixture will go off like a miniature bomb, resulting in bent engine parts and sadness.Ī map is a set of instructions programmed onto the car’s ECU by the manufacturer to handle the fuel air mixture and hundreds of other parameters. Too much fuel and the combustion won’t be explosive enough or it won’t ignite at all. Those mechanical parts are pistons, connecting rods, clutch, gearbox, driveshafts, and more. Through lots of mechanical parts this causes a driving force against the wheels and makes them spin. It burns (combusts) inside the engine explosively.

The thought of doing that sort of DIY remap makes my brain hurt.

Some people are happy to just download a free remap from bit torrent and put on their car. I’m not a big risk taker, so I did things carefully. We spent a lot of time reading and researching before buying our first remap tool and plugging it into a car. We only know a fraction of what is neccessary to remap a car, or how to remap a car on your own, but we’ll share what we do know. So you want to learn how to remap? Well it’s not easy. The long answer is – yes, but it’s complicated. Can I remap my car? Can I remap my ECU myself? The short answer is yes.
