Stage 1 Torque

The Citroen C4 Picasso 1.5 BlueHDI 100 come fitted with a Bosch MD1CS003 control system. This advanced ECU demands a skilled tuner for precise torque model adjustments which satisfy all of the ECUs reverse tuning protection maps. Basically we have to remodel everything inside the ECU and hundreds of maps must be changed just for a stage 1 tune. Bench programming is required for this ECU. Most genuine tuning tools can accomplish this without the need to open the ECU.

If you have a programming tool that can connect to the Bosch MD1CS003 ECU then you can also use our online remap service.

Programming Methods – bench programming

The Bosch MD1 ECU can be programmed using Bitbox and a Scanmatik 2 device.

Programming via Bench service mode over CAN with Bitbox

This is our preferred way to program. The ECU must be removed, but there is no need to open the ECU and risk damage. A full backup can be made of both the EEPROM and the internal flash memories.

  • Order a Scanmatik 2 Pro J2534 programming device and a Bitbox dongle with the MD1 license.
  • Remove ECU from the vehicle.
  • Connect specified wires to ECU plug connector.
  • ID the ECU.
  • Read the ECU memories.
  • Email software to HDI Tuning.
  • Wait for us to prepare your remap and return it back to you.
  • Program the remap to the ECU using the same method taken to read the ECU.
  • Refit the ECU, check engine starts.
  • Let your engine warm up and then take the car for a spin, enjoy the extra power!
