Bom dia, estou tentando conectar a ECU do meu FIAT STILO 1.8 8V, o elm327 1.5 está comunicando como pode-se ver no teste abaixo, porém quando eu conecto na ECU, não aparece nenhuma informação, e simplesmente não responde aos comandos, mas a conexão é feita com sucesso, sem falhas. Simplesmente não atualiza as informações. Estou sem cotas para anexar arquivos de imagem para que seja possível um melhor entendimento do meu problema. Peço gentilmente a ajuda de vocês.

This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules.

Hi,
does anyone have experience with this ELM 327? Which resistor needs to be desoldered to work on the Lancia?





Thank you

hi, this tool connects only to the engine control unit, I have another modified tool where it was easy to locate the 120 ohm resistor, please can you tell you how to unlock these new models .. thanks

Hi,

First post here.

I'm comming from Android & Windows to iOS 15 and MacOS 11,8 ,

I have like 10-11 OBD2 items, mainly bluetooth but somes are Wifi for iOS.
Bluetooth are OK with Android but ton iOS
Any of my OBD2 Wifi works with Multiecuscan iOS

I just bought a MES OBD2 Wifi on Multiecuscan.it, this one https://www.multiecuscan.it/en-us/multiecuscan-ios-elm-327-wifi-iphone-ios/
Hope this one will works with my Iphone 12 Pro Max coz we cannot use Bluetooth OBD (if they aren't OBDLink MX+ over 120 EUR)
I'll back with my result.

Hi i have a fiat Stilo. i connect Fiatecuscan 3.6 with a ELM 327 1.3+ clone. all works fine, except for some functions that has strange behavior.

for Example steering wheel align : when start procedure and FES instruct to move steering on left after 1 sec without time to move procedure ends and FES return on main menu.

In this days i have some issue with alarm and i want to turn off. On FES Menu i have to input Electronic code and always receive "code not valid"(but i write original code from card).

Strange is that after three times i should have to wait 30 mins, but this is not true. i can try as often as i want.(always same error).

I don't understand if it is a FES issue or a ELM issue.

Thanjks for answer

I have the same unit and it connects to the engine and gearbox modules but no others.

I am considering correcting it but was going to remove R2 as this is the only 121 ohm resistor on the board.

This is my interface.
Witch resistor must be removed?

Hi, have you found which resistor has to be removed?
