Volvo L120 Wheel Loader Tuning and Power Upgrade
The Volvo L120 is Volvo's wheel loader. The engine control unit (ECU) software is recalibrated on the machine's own original file; the original software is backed up.
Volvo L120 power remap
A power remap on the Volvo L120 recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. On a loader the engine feeds both the drivetrain and the bucket hydraulics; with more torque in reserve, rpm drops less when entering the pile and climbing ramps with a full bucket.
Volvo L120 AdBlue fault solution
Loaders shuttle back and forth over short distances; the particulate filter (DPF) often fails to reach regeneration temperature and blocks. With an EGR fault or a NOx sensor fault in the AdBlue (SCR) system the machine enters limp mode and loading stops at the quarry or plant. The cause is diagnosed first; the software solution is applied according to the ECU type.
ECU and compatibility for the Volvo L120
Services with a verified solution for Volvo in our library: Stage 1 Remap and AdBlue / SCR Delete. The control units we work on in Volvo machines include DENSO 112500-1XXX, DENSO 275700-1201/3410/3411/3412, CONTINENTAL VDO ACM and CONTINENTAL SIEMENS-VDO ATK-EM-EU6. The same model can carry a different ECU depending on build year and engine option, so we confirm compatibility for the Volvo L120 from a photo of the ECU label or from the file read out.
Where is the difference noticed on the Volvo L120?
- Entering the pile and filling the bucket
- Climbing ramps and slopes with a full bucket
- Truck loading, where cycle time matters
