JCB 3CX power remap

A power remap on the JCB 3CX recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. On a backhoe loader one engine feeds the front bucket, the rear excavator and the drivetrain; with more torque in reserve, rpm drops less when digging and roading.

JCB 3CX DPF, EGR and AdBlue fault solution

Backhoe loaders often sit idling between short jobs during the day; in these conditions the particulate filter (DPF) cannot clean itself and blocks. The EGR valve collects soot; with a NOx sensor or pump fault in the AdBlue (SCR) system the machine enters limp mode. The cause is diagnosed first; the software solution is applied according to the ECU type.

ECU and compatibility for the JCB 3CX

Services with a verified solution for JCB in our library: Stage 1 Remap, DPF Delete, EGR Delete and AdBlue / SCR Delete. The control units we work on in JCB machines include DELPHI DCM7.24, DELPHI DCM3.3 / DCM3.3+, MOTOROLA CM850 and BOSCH EDC17CV41. The same model can carry a different ECU depending on build year and engine option, so we confirm compatibility for the JCB 3CX from a photo of the ECU label or from the file read out.

Where is the difference noticed on the JCB 3CX?

Working in hard ground with the rear excavator
Loading and grading with the front bucket
Roading between sites and on hills
Working with hydraulic attachments such as breakers

Frequently asked questions

Which software services are available for the JCB 3CX?

Services with a verified solution for JCB in our library: Stage 1 Remap, DPF Delete, EGR Delete and AdBlue / SCR Delete. We confirm on the file which of them apply to the ECU fitted to your JCB 3CX.

How much power does the JCB 3CX gain with a remap?

The gain depends on the engine option, the ECU type and the machine's power level within its range. Rather than quote a fixed figure, we read the original file first and tell you what increase is possible.

How do I find out which ECU my JCB 3CX has?

The exact type is read from the label on the ECU or with a diagnostic tool. A photo of the label and the model year of the machine are enough.

How long does the job take, and can it be done on site?

Most ECUs are read and written through the diagnostic socket and the job is completed the same day; some units are removed and worked on the bench. Contact us for on-site service.

Can the original software be restored?

Yes. The original software is archived and the JCB 3CX can be returned to its factory setting on request.
