Citroen C4 Cactus 1.5 BlueHDI 100 Stage 1 Remap (130 BHP | 300 Nm)

Our extensive research on the 1.5 BlueHDI Engine has led to a superior Stage 1 remap. This tuning upgrade elevates your engine’s output to 130 BHP and increases torque to a robust 300Nm.

This remap’s torque profile expertly mirrors that of the higher-spec 130 BHP variant, ensuring your Citroen C4 Cactus’s performance is both exhilarating and reliable. It integrates the proven MHI TD02L11 turbo, renowned for its early activation and durability, refined specifically for the 1.5 HDI engine. We calibrate a modest increase in turbo pressure, always staying within the safe operating range.

Driving your remapped Citroen C4 Cactus, you’ll immediately notice an enhanced throttle response, increased torque in the lower to mid-range, and sustained power at higher revs. The transformation in driving experience is something we’re confident you’ll be thrilled with.


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!
