I am changing stock ECU to ECU master black. For more detailed engine setup and assignment of various sport modes. I will make a pnp adapter with additional LSU 4.9, fuel pressure, oil pressue and MAC boost solenoid. Now the car is at my tuner. Does anyone have such experience?
SDS-Delta offers a PnP solution for the Megane 2/Clio 3. Under the settings, the OEM can protocol is listed as "Megane/Clio/Twingo", which is a pretty good confirmation they use the same CAN protocol. You should be able to select the Clio 3 CAN protocol on the EMU Black and everything should work (CAN-wise). The EMU black does not support OBD2 nor Cruise control. The SCS-Delta does. That's my 2 cents.
