Use the Galletto 1260 tool to read/write your ECU

Below are some brief instructions to follow when using the Galletto 1260 tool to read/write your ECU.

How to read the ECU:

1. Prior to connecting the Galletto 1260 you must copy the software from the mini disc and add it to the desktop on your laptop. If you don’t have the disc the software is available on the HDI-Tuning website.
2. To use the software, connect the USB end of the Galletto 1260 into the laptop.
3. Connect the OBD lead to the cars diagnostics port. This is usually beneath the steering wheel in the fuse compartment.
4. Open the programme named ‘New Serial’. Wait 30 seconds.
5. Switch on the ignition key to two clicks, don’t start the engine.
6. Select Peugeot/Citroen, Bosch EDC 15 C2 29f400BT .
7. Select ECU data.
8. Select read data, you can then name and save the file.
9. When finished, wait for the message (which is in a different language, but tells you to switch off the ignition and wait for ten seconds).
10. Switch off the ignition and then click ok. Wait ten seconds, then switch on and press ok.

You should now have a copy of your original file on your laptop.
