Hi guys!

I have the same ecu... micro 4E28B (MC68HCP11E1VFN): when I try to read the mcu, UPA show me message "RST high Error".

MCU could be protected?

Hello M8,
I have Renault Megana 2002, all key lost condition please I need to off the Immo, what did I need to do that? Is the code on ECU or immobilizer?

you will need to find the Micro who have the Immo info, read them and change the lines of data, there are some programs can do that.
To read, you will need one machine to read like UPA. Its not so hard, but u need to be carefull, one simples mistake and u will lose the data..

Where will I get the data from is it on BSI or ECU, please how can I key the Immo data???

I dont know to, but the process is that, you can search here in forum or in google, with the number from ECU and BSI.
With this numebrs you will find exacly where you need to read to get the immo data.

HI mate. Thank you. Today I do the same ECU with your method and works fine.

I only have cut the cable from the pin 29 (immo).
