Dongfeng Truck ECU Tuning Files
Dongfeng's heavy range includes well-known families such as the Tianlong and Tianjin trucks and tractors. For Dongfeng engine files, our service supports four Bosch diesel ECUs: EDC16C39, EDC17C53, EDC17CV44 and EDC17CV54. You read the original file with your own tool, upload it, and receive a modified file built for that exact ECU. The table below lists the modules supported on each unit.
On the EDC17C53, EDC17CV44 and EDC17CV54, Stage 1, DPF, EGR, AdBlue/SCR/NOx and DTC work is done directly in the engine ECU file, alongside torque monitoring disable. The EDC16C39 covers Stage 1, DPF, EGR and DTC too, plus speed limiter (Vmax) removal and MAF, lambda, catalyst, swirl flap, hot start fix and IMMO options. Exact module availability is confirmed by the automatic analysis once your file is uploaded. Emission-related modules are intended for off-road, motorsport or export use where local rules allow.

Frequently asked questions
Which ECUs are used in Dongfeng trucks?
Our Dongfeng truck files cover four Bosch engine control units: EDC16C39, EDC17C53, EDC17CV44 and EDC17CV54. The unit in your truck depends on the engine and production year, so check the ECU label or the identification your reading tool shows, then upload the original file for automatic analysis.
Is AdBlue Off possible on Dongfeng EDC17CV44?
Yes. AdBlue/SCR/NOx removal is supported on the Bosch EDC17CV44, as well as on the EDC17C53 and EDC17CV54. On these units it is done in the engine ECU file itself, so you upload the engine ECU read rather than a separate aftertreatment unit file. It can be combined with DPF, EGR and DTC modules, and the automatic analysis confirms what your specific file supports.
Can the speed limiter be removed on a Dongfeng truck?
Speed limiter (Vmax) removal is listed for the Bosch EDC16C39, alongside Stage 1, DPF, EGR and DTC. For the EDC17C53, EDC17CV44 and EDC17CV54, the listed modules are Stage 1, DPF, EGR, AdBlue/SCR, torque monitoring disable and DTC. Upload your original read and the automatic analysis will show every option available for that specific file, including speed limiter work where it applies.
Is DPF off available for Dongfeng?
DPF off is supported on: BOSCH EDC16C39, BOSCH EDC17C53, BOSCH EDC17CV44 and BOSCH EDC17CV54. Euro 3–5 vehicles without a particulate filter do not need this module.
