Rolling road tuning: Standalone ECU & Renault RS mapping

Megane 250 / 265 / 275 Trophy factory restore of ECU (unlock)


ECU unlocking service. Factory reset including removal of 3rd party maps and security lock.


We can reset all Renault Megane 250 / 265 and 275 Trophy ECUs to factory standard should you find yourself with a locked ECU.

A locked ECU can occur when a 3rd party mapping tool has been used to flash a map to your ECU. Often these maps are locked for IP protection, but can also mean that another tuner can no longer read/write to the ECU in the normal way preventing it from being re-mapped.

By ordering this item and posting your ECU to us we will unlock the ECU, inspect the software, restore it to factory if necessary and return it to you typically within two working days of receiving it.

To do this via post:
Please send your ECU with a covering note which includes your name and return address to:
Mr C. Backshell
EFI Parts
Unit 16 Dewar Court
Astmoor industrial estate

If you have any questions or would like some other work performed with your Renault sport ECU, please don’t hesitate to get in contact.
