Dacia Duster, Sandero and Logan Chip Tuning: EDC17C42, MD1CS006, DCM3.4 on 1.5 dCi and TCe
The Dacia Duster, Sandero and Logan are best-sellers. On the diesel side they use Renault’s 1.5 dCi; depending on model year the ECU is the Delphi DCM3.4, Continental SID305 / SID310, Bosch EDC17C42 or, on the new Blue dCi, the MD1CS006. The TCe petrol uses the Continental EMS3141. Solutions for Dacia are available at ECU Prime on these ECUs.
