ECU file desk guide: how a workshop order runs

Reviewed by the lab engineers. Circuit / motorsport only.

This page is the map of the desk. A workshop sends a read. We write a file on that read. The file comes back in the portal. That is the whole job.

You need three things before anyone writes. An account, credits on the account, and the original dump from the car on the ramp. 1 credit is 1 euro. Credits do not expire. We do not host the bin. You put the original on Dropbox, Google Drive or MEGA, 5 MB at most, and paste the share link on the ticket.

Stage 1 means the car is still stock. Same turbo, same exhaust. The map uses the torque earlier. It is not a dyno promise. The short explanation is what a Stage 1 remap is. If parts have already changed, that is a different file. Read Stage 1 versus Stage 2 before you pick the job.

Prices are on three lines: the Stage 1 file, the Stage 2 file, and the TCU file. Stage 2 needs the parts written on the ticket. Downpipe, intake, intercooler. We will not guess them from the year. The gearbox is its own file when the engine map would otherwise hit the stock torque limit.

On the ticket write the model, the year, the engine code, the gearbox, and whether the car is already on a map. If it tows, sits in town, or does a Saturday on track, write that too. An empty ticket does not speed the file up. It stops it, because the engineer has to ask.

How the file travels is in how to send an ECU file. Keep the read you sent. If the stick from 2019 is gone, the original ECU file is the way back to stock, only if we still have that dump. We cannot invent an original we never saw.

A forum file can start. It can also carry someone else's immobiliser and a torque limit from another gearbox. We write on the dump in front of us. Brand pages name the engines in that queue: BMW, Volkswagen, Audi, Mercedes-Benz. If your engine is not on the list, the ticket still works.

After the flash, a small trim on the same read stays on the job. A new turbo is a new ticket. If the clutch is already tired, more torque finds it. That note is clutch after Stage 1. Fault codes, if you need the number, are on the DTC list.

DPF, EGR, AdBlue and pops are circuit and motorsport files. We do not homologate them for the public road. You flash with your own tool. We do not remote-flash the car. Watch the battery while you write. A weak battery is how a good file becomes a Monday tow.

If this is your third car this week, you do not need the guide again. Fill the ticket the same way as the first one. If you are new, read the Stage 1 note, send a clean dump, and name the job. Circuit and motorsport only.
