1.6 dCi 90/115 2013-2016 Bosch EDC17C42 EU5 Renault Trafic

145 BHP

Stage 1 Power

350 Nm

Stage 1 Torque

The 1.6 dCi Euro 5 engine came in several variants when fitted to the Renault Trafic, usually these are 90 or 115 BHP and sometimes even 120 BHP when fitted with the Bosch EDC17C42 ECU.
These are all fitted with the same components so we see the same results from a stage 1 remap. If you would like a simple factory upgrade from 90 to 120 that is also an option.

We’ve now got a ‘program at home’ option for the EDC17C42 ECU, supported by the MyGenius OBD Programmer unit. This device makes it super simple and safe to program the ECU yourself. The only additional equipment you’ll need is a battery charger/stabiliser.

Renault Trafic 1.6 dCi Stage 1 remap (145 BHP | 350 Nm)

The Stage 1 remap gives a modest boost in power making the van a lot nicer to drive day to day and much safer when over taking. The Stage 1 remap will also help save a little fuel during normal driving as there’s more low down torque, and when you need the extra power it’s there to use.

With 145 BHP it’s a respectable jump up in top end power, and the torque figure will increase to 350Nm which will make your van a lot more fun to drive.


Programming Methods – OBD2 or bench programming

Only genuine tuning tools can program the EDC17C42 over OBD such as Autotuner, Kess3 and now you can also program this ECU type from home using Dimsport MyGenius.

Recommended programming method:

Program over OBD using the Dimsport MyGenius standalone tool


The Dimsport MyGenius tool is the safest, easiest and most reliable way to program your ECU from home. Simply connect to the OBD port and let the tool do the work, no need to remove your ECU or bench program for most ECU types. For more information have a read here

Programming via Bench service mode PCM Flash or any tools with bench service mode

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, also the external flash can be read on models where this is present.

  • Order a tool such as PCM Flash.
  • 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!

Programming via OBD EDC17C42

  • Obtain a suitable programming tool. We recommend Dimsport MyGenius if you want to program over OBD.
  • Install the tool to a reliable laptop.
  • Connect to the OBD port of your car, make sure you have backup chargers to the vehicle battery and the laptop battery.
  • ID the ECU and then take a read of the ECUs flash memory.
  • Email the software to along with a description of the remap you require.
  • Send payment through our webshop.
  • We will modify the software and send back to you. This normally takes less than 2 to 3 hours during working days.
  • Using the same tool, ID then write to the ECU. This will overwrite the ECUs flash memory, it’s important not to interrupt the process. If you encounter any problems we can fix the ECU for you so there’s absolutely nothing to worry about.
  • Let your engine warm up and then take the car for a spin, enjoy the extra power!
