Volvo Trucks ECU Tuning Files
Volvo Trucks builds the FH, FH16, FM and FL ranges, and our file list for the brand covers Bosch MS6.2, MS6.3 and EDC7UC31, Lucas, and the TRW EMS2.0, EMS2.2, EMS2.3 and EMS2.4 family. Stage 1 and DTC are offered on every engine ECU in the list, while the emission modules depend on the unit: EMS2.0 and EMS2.2 ECMs carry DPF, EGR and AdBlue/SCR, and EMS2.3 and EMS2.4 ECMs carry EGR and full emission removal. The TRW EMS2.3 ECM is confirmed on Euro 6 FH 460, 500 and 540, FH16 550 and FL 210.
On EMS2.2, EMS2.3 and EMS2.4 systems AdBlue/SCR is also handled by a separate aftertreatment unit (ACM), so the ACM file is processed on its own alongside the engine ECU. Upload the original file read with your own tool and the automatic analysis confirms which modules are available for that exact software. Emission-related modules are intended for off-road, motorsport or export use where local rules allow.

The exact module availability for your vehicle is confirmed by the automatic analysis after you upload the original ECU file.
Modifications that disable emission control equipment are intended for off-road, motorsport or export use. Removing or disabling such equipment may not be legal for road use in many countries; checking local regulations is the vehicle owner’s responsibility.
Frequently asked questions
Which ECUs are used in Volvo trucks?
Our Volvo Trucks list covers Bosch MS6.2, MS6.3 and EDC7UC31, Lucas, and the TRW EMS2.0, EMS2.2, EMS2.3 and EMS2.4 engine ECMs. For EMS2.2, EMS2.3 and EMS2.4 the separate ACM aftertreatment unit has its own row in the table. Confirmed applications include the EMS2.3 ECM on Euro 6 FH 460, 500 and 540, FH16 550 and FL 210, and the EMS2.3 ACM on FH 13 500. For other trucks, the uploaded file identifies the exact unit.
Is AdBlue Off possible on Volvo FH with EMS2.3?
On EMS2.3 trucks AdBlue/SCR is managed by the separate ACM, not only the engine ECM. The EMS2.3 ACM is listed with full emission removal and DTC, and the EMS2.3 ECM with EGR removal, full emission removal, Stage 1 and DTC. FH 13 500 is a confirmed EMS2.3 ACM application. Upload both the ECM and ACM files and the automatic analysis confirms what is possible for your software.
Can I get a Stage 1 file for a Volvo EMS2.4 truck?
Yes, the TRW EMS2.4 ECM is listed with Stage 1, EGR removal, full emission removal and DTC. The EMS2.4 ACM is handled separately with full emission removal and DTC. Exact availability depends on the software version, which the automatic analysis checks as soon as you upload the original file.
Is DPF off available for Volvo?
DPF off is supported on: TRW EMS2.0 - ECM and TRW EMS2.2 - ECM. Euro 3–5 vehicles without a particulate filter do not need this module.
