Delphi DCM7.1AP & DCM7.24 DPF, EGR, AdBlue, Stage 1 Solution

Our software solutions for the Delphi DCM7.1AP and DCM7.24 engine control units, used in pickups and light commercial vehicles, are complete. These two units belong to a different family from the DCM7.1A found in Peugeot and Citroen, so their files are prepared separately.

Solutions developed

• DPF off: particulate filter regeneration and related fault codes
• EGR off: EGR valve control and EGR related faults
• AdBlue / SCR off: dosing, warnings and limp mode
• NOx sensor off: NOx sensor faults and related codes
• IAT off: intake air temperature sensor faults
• Stage 1: vehicle-specific power and torque remap

Which vehicles?

The DCM7.1AP and DCM7.24 are mainly found in Chinese and Japanese pickups and light commercial vehicles: Great Wall (Poer, Wingle, Haval), Isuzu (NKR, KV series), Foton (Tunland, Aumark, Ollin), JAC (T8 Pro, T9), Dongfeng, Changan and JMC. Typical engines are 2.0, 2.3, 2.4, 2.8 and 3.0 litre turbo diesels plus the 4.2 and 4.3 litre engines in light trucks. Exact compatibility depends on the ECU variant and software version; we check this from the read file before the work starts.

How it works

On supported variants the ECU can be read and written via OBD. The original software is read and backed up, the solution is built on the vehicle's own file, the checksum is corrected and the vehicle is tested. The original backup is kept, so the vehicle can be returned to factory software at any time.

For workshops: ECU Prime

DPF, EGR, AdBlue and Stage 1 solutions for DCM7.1AP and DCM7.24 files are live on the ECU Prime file platform. Coming soon: ECUPRIME Software. Details and file orders: ecu.primechiptuning.com

Emissions-related work is offered only where local regulations allow it (e.g. off-road, competition, export); compliance is the owner's responsibility.
