About this file
This page covers one exact calibration: Bosch EDC7UC31 with software 0281020103 1037377875, as indexed on the Dongfeng Chenglong WP12.430N 11.6L 6L. Work is done on your own original read — we do not send a generic file for the controller family, because two vehicles sharing a controller can carry different maps, limiters and diagnostics.
Send the file exactly as your tool saved it and tell us which tool produced it. You get the modified file back in the same format, with the checksum corrected, ready to write. Turnaround is 1–3 hours for the solutions listed as available below.
If your readout shows a different software number from the same family, use the version list at the bottom of the page — every calibration we have indexed has its own page.
Everything on this page is reference information. Not finding your exact version here does not mean we cannot do it — a solution can be developed for any calibration. Create an order on the file service and send us the original read.
What can be done on this ECU
These are the services offered for the Bosch EDC7UC31 and their list prices. Ordering several in one file is cheaper — the calculator below applies the bundle rules.
| Service | Price | Notes |
|---|---|---|
| DPF/FAP Delete | 180 € | |
| EGR/AGR Removal | 95 € | Please remember that on this truck the EGR is part of the hill-hold brake system, and you cannot disconnect the EGR plug because the wiring is shared between the EGR and the hill-hold brake system. You should block the EGR mechanically and keep the plug connected. |
| SCR/AdBlue OFF | 180 € | If you disconnect the SCR ECU, a dashboard message will appear that cannot be removed, because the CAN wiring runs from the DCU to the instrument cluster and this cannot be solved by modifying the engine ECU alone. For a full delete, a DCU read is required; otherwise, keep everything connected. |
| Stage 1 tuning file | 120 € | Please visit our website's tuning catalog to see the final results after Stage 1: https://auto-remap.com/catalog/trucks |
| Throttle Valve TVA Disable | 95 € | |
| Swirl valve/Flaps OFF | 95 € | |
| DTC's selectivity OFF | 60 € | |
| Stage 1+/Stage 2 tuning file | 180 € | |
| Full Immo OFF eprom | 120 € | Immo OFF is possible only for trucks with a manual gearbox! The solution does not work with an automatic gearbox. For Immo OFF, please attach both flash and EEPROM reads to your order. |
| Checksumm correction | 50 € | Checksum correction: select this option ONLY if you really need a checksum correction and your tool does not do it automatically, because this option is charged additionally! |
| Back to ORIGINAL file (restore file to original) | 50 € | Please select this option only if you really need to restore all changes to the original. If, after our check, the attached file turns out to be already original, the order will be completed and the cost of the check will be deducted from your account! This is because checking and comparing the file with our original database takes the same time as restoring it to the original. |
