JCB 531-70 Telehandler Tuning and Power Upgrade
The JCB 531-70 is JCB's telehandler. The engine control unit (ECU) software is recalibrated on the machine's own original file; the original software is backed up.
JCB 531-70 power remap
A power remap on the JCB 531-70 recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. On a telehandler the engine feeds both the drivetrain and the boom hydraulics; with more torque in reserve, rpm drops less when manoeuvring with a loaded boom and towing a trailer.
JCB 531-70 DPF, EGR and AdBlue fault solution
Telehandlers work on farms and sites in short jobs with frequent stops; in these conditions the particulate filter (DPF) cannot clean itself and blocks. With an EGR fault or a NOx sensor 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 531-70
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 531-70 from a photo of the ECU label or from the file read out.
