| Read / write | Bench read, custom development |
The situation
Liebherr’s in-house LIDEC2 controller is not covered by the usual tuning tools and file portals – there is no off-the-shelf solution. That is exactly the kind of platform our development team likes: reverse engineering the ECU, understanding the checksum and the map structure, and building a solution that is stable in the field.
The L580 in question is a quarry machine. The owner wanted more power on the ramp and an end to recurring AdBlue-related fault codes.
What we did
After the LIDEC2 was fully decoded, we developed a performance calibration for this L580 and handled the SCR fault logic in software.
- Performance file: more torque and power for loading and ramp work, within engine and driveline limits.
- AdBlue/SCR: fault codes and inducement handled – no more interruptions from the after-treatment system.
- Checksum handled correctly for the LIDEC2 – the file is accepted by the ECU without workarounds.
The result
A clearly stronger loader on the ramp and under the bucket, no more fault-code interruptions, stable operation in continuous quarry use. LIDEC2 solutions are now available for other Liebherr machines on request.
