Hidromek HMK 640WL Wheel Loader Tuning and Power Upgrade
The Hidromek HMK 640WL is Hidromek's wheel loader. The engine control unit (ECU) software is recalibrated on the machine's own original file; the original software is backed up.
Hidromek HMK 640WL technical data
Each row states where the data comes from. “Manufacturer data” is the factory figure published by the manufacturer; figures after a remap are shown only where we have our own measurements and records. Estimated figures are not guaranteed results.

Hidromek HMK 640WL power remap
A power remap on the Hidromek HMK 640WL 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.
Hidromek HMK 640WL DPF, EGR and 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 Hidromek HMK 640WL
Services with a verified solution for Hidromek in our library: Stage 1 Remap, DPF Delete, EGR Delete and AdBlue / SCR Delete. The same model can carry a different ECU depending on build year and engine option, so we confirm compatibility for the Hidromek HMK 640WL from a photo of the ECU label or from the file read out.
