Citroen C1 2005 remap
Diesel · Flash via OBD · Figures published for this engine · Remote remap available UK-wide from £199
Is a remap worth it on the Citroen C1 2005?
This is one of the stronger candidates for a remap. The factory map leaves a lot on the table and a Stage 1 flash recovers most of it with no hardware.
What each stage needs
| Stage | Power | Torque | Hardware |
|---|---|---|---|
| Standard | 55 bhp | 130 Nm | None |
| Stage 1 | 84 bhp | 184 Nm | Software only |
| Stage 2 | 84 bhp | 184 Nm | Uprated intercooler, high-flow intake, sports catalyst |
Risk on this engine: high
- Very high 53% gain: approaching stock component limits.
- Diesel: no knock risk. Primary risks are EGT, turbo health, and injector wear.
How to keep the risk down
- Full engine health inspection mandatory.
- Uprated intercooler and charge pipes required.
- Oil cooler upgrade strongly advised.
- Monitor EGT under hard driving: sustained temps above 700 C accelerate turbo wear.
- DPF (if fitted) will accumulate soot faster: ensure it is in good condition.
- Keep a copy of the original ECU file before flashing.
