Its like fenix5 but renault decoder dont work with this... you must search eeprom or flash and to pin 22 or 23 put a ground many times. you must work on bench, try to search on google renault immo decoder pdf for scheme.

i have same on megane 1.6
youmust have a mil light, when you turn on ignition mil glow up for thre seconds and than blinking. you now put ground on 22 or23 pin on flash or eeprom and mil goes glow up. Than off ingnition and try it. If mil glow permanently, turn off and cut a immo wire.

If i help you, push thanks button please:chuncky:

like this https://www.youtube.com/watch?v=n7kq1HTUjYo but you need only ground wire to eeprom or flash... work fine, im tested on many cars... dont forget cut a immo wire...http://www.ad-by.com/content/images/product/1227259371_Renault%20ECU.pdf page 8 ist your ecu.... immo wire for 3.0l is 35

Sorry, so I need TMS374 Decoder (maybe Julie) or I don't need any interface, but just ground wire? :)

[Pyromaniak]

yes only ground, see video, if not work on first try, try more. I think 5 times on 1 second, or ground one second. I have julia and decoder too, but this setup is for free, i try it too and realy work it. I made lots of renaults. I love renaults

[Pyromaniak]

For me with wire get immo under one minute, http://automobiles.fredericbazin.fr/PDF/immo/immotool/ecu-decode.pdf here is better sheme to a mil config. When mil gets light permanently you win ,cut immo line and enjoy.:celticscarf:
(mil turn off after start, but immo led are blinkink, must in dash cut off) expect the worst cut silicon off.

Thanks for the answer, I will try these solutions these days and report here.

[Pyromaniak]

ok report here :) i think immmo isnt in eeprom, or flash but in procesor memory, this pin make reset data on procesor. ecu is virginized and wait for data from immo. This ecu work blank( without data from immo line) if you dont cut a immo line in car or on ecu, ecu learned code from immo box. i have this motor from espaceII i will to put on R5 (like R5turbo) i try to make replica (more like tuned replica :D ) this motor are used in renault alpine?s and safrane biturbo R25 Baccara:D I make for renault 10 years

Hi again. I cutted some part of the silicone in ecu, there is TMS 27PC256. Solution for this?

419469

PS: Also there is TMS 374 C003

read tms374 for off and post here dump

Put in car or bench, make wire with some rezistor and try pin 19, 20 or 21 to gnd if mil stop blinking you win, i think its a same but chip has different shell

Gnd on 27pc256 or TMS374c003 ?

[Pyromaniak]

27cp256 sorry

[Tawe]

Mhm ok, but I have one problem, I connect lamp to pin 26, but lamp wont turn on.
Tried also on pin 43, its on and not blinking.

[Pyromaniak]

and in car blinking? lamp must be max to 5 wats ... Lamp must be conected to positive, ecu making ground
