AutoTuner Boot Mode ECU Tuning on Peugeot 208 1.6 THP

 Autotuner Peugeot 208 1.6 THP 200 Bosch MEVD17.4.2 ECU tuning review:

This wasn’t an OBD-and-done job.
The ECU arrived by post and required direct boot-mode access, meaning the ECU had to be opened, connected directly to the PCB and read at processor level before any work could begin.
That is exactly the kind of work we increasingly handle in-house rather than sending ECUs elsewhere.

Vehicle details
2014 Peugeot 208 GTI
Engine: 1.6 THP Petrol
Standard power: 200 bhp / 275 Nm
Transmission: Manual
ECU: Bosch MEVD17.4.2
Read type: Full Read

Once the ECU arrived, it was opened carefully and connected directly using boot programming equipment.

A full ECU read was taken first, giving us the original data and recovery information before any modified calibration was written.

Calibration completed
* Custom Stage 1 calibration
* Soft rev limiter removal
* Relevant DTC calibration
* Full original ECU backup
* Checksum correction
* Boot-mode programming
* ECU resealed and prepared for return

On this engine, the biggest improvement is in the torque delivery.
An additional 85 Nm transforms the way the car pulls through the mid-range, while still keeping the calibration appropriate for the standard turbo and supporting hardware.
Once programming was completed successfully, the ECU was closed back up, packed securely and posted straight back to customer.
