Renault Trucks ECU Tuning Files
Renault Trucks covers long-haul, distribution and construction work with the T, C, K and D ranges, and older models such as the Magnum, Premium, Kerax and Midlum are still common in fleets. On the engine side we support TRW EMS2.0, EMS2.2, EMS2.3 and EMS2.4 engine controllers (ECM), Bosch EDC17C45 and the older Bosch MS6.2, MS6.3 and Lucas units. Services include Stage 1, EGR Off, DPF Off, AdBlue/SCR/NOx Off, Full Emission Off and DTC delete. The Euro 6 T, C, K and D generation from 2013 on, including the T 520, uses the TRW EMS2.3 ECM.
On EMS2.2, EMS2.3 and EMS2.4 trucks, AdBlue is handled by a separate aftertreatment control module (ACM), so the emission solution usually needs the ACM file as well as the ECM file. Upload the original file read with your own tool, and the automatic analysis confirms which modules are available for that exact software. Emission modules are intended only for off-road, motorsport or export use, where local rules allow it.

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 does Renault Trucks use?
Our Renault Trucks list covers TRW EMS2.0, EMS2.2, EMS2.3 and EMS2.4 engine controllers (ECM), separate ACM aftertreatment units for EMS2.2, EMS2.3 and EMS2.4, Bosch EDC17C45, and the older Bosch MS6.2, MS6.3 and Lucas systems. The Euro 6 T, C, K and D range from 2013 on, including the T 520, uses the TRW EMS2.3 ECM. For other models, the file analysis identifies the exact unit.
Is AdBlue Off possible on Renault T 520 with EMS2.3?
On EMS2.3 trucks, AdBlue/SCR is handled by the separate ACM unit. Our data lists Full Emission Off and DTC delete for the EMS2.3 ACM rather than a standalone AdBlue Off module. The EMS2.3 ECM supports EGR Off, Full Emission Off, Stage 1 and DTC delete. In most cases you send both the ECM and the ACM file, and availability is confirmed by the automatic analysis.
What can be done on older Renault trucks with Bosch MS6.2, MS6.3 or Lucas ECUs?
For older Renault trucks with Bosch MS6.2, MS6.3 or Lucas ECUs, the supported modules are Stage 1 and DTC delete. These earlier systems have no DPF, EGR or AdBlue modules in our list. Upload the original read and the automatic analysis will confirm what is available for that software version.
Is DPF off available for Renault Trucks?
DPF off is supported on: BOSCH EDC17C45, TRW EMS2.0 - ECM and TRW EMS2.2 - ECM. Euro 3–5 vehicles without a particulate filter do not need this module.
