Hello,

I need your support to do Immo Off for the next car:
Renault Megane
1.4, 16V, AC manual, normal key, 2001

I have read a lot about this topic and seams that it could be solution for this Sirius34 as Immo Off without emulator, only sw.

Therefore please let me try your solutions, and I will report if it is working or not!

Attached you can find the 29F400BB full read out of external programmer!

So feedback!

I have written the Shortz file into the flash.
The Ecu was on the car but the car didn't started with light ON into dash.

Now I have read again - and surprise - the sw is modified? like into attached file.

I do not how should I interpret this!

cut inmo line pin 27 before fit ECU

did you cut immo line ???

[mishu_b]

...
yes - I have cut the wire which connect the pin 27!

for me looks like the immo from uC write back something.

should I lift up the pin WE and connect to VCC for write protection?

...
I have tried also with lifted up the pin WE then I connected this pin to 5V via 220K resistance (current limitation protection) still not working. :(

Any other idea will be more then welcome!

thanks
