Issue with brazilian Fiat

[caioferrari]

Hi,
I have a "Made in Brazil" Fiat, a Fiat Uno which uses a 1000cc Fire Engine (year model 2007). The injection used is a Magneti Marelli IAW 4AFB (The "B" is something about "Brazillian", I think).

I got a chinese ELM 327 V1.4 bluetooth adapter. Exactly this: http://dx.com/p/elm327-mini-bluetooth-v ... 12v-160462

I've connected it with my Windows 7 laptop. I waited for windows search and install all required drivers and everything seems to be fine. So, I've opened MultiECU scan and went to "settings". There I got me adapter recognized as a V1.4 (the chinese said it is a 1.5...) which should work with all ECU models. The "test" function shows everything ok
"This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules."

I've selected a similar vehicle on MultiECU list, a 1242cc Fiorino which uses the same ECU as my Uno. So I tried to connect and got some different errors:

- ECU connection failed! Check your cable and port settings
- Connection Timeout .... (I don't remamber more)
- Can't connect with COM7 port... (Which I solved with a computer restart)
- Semaphore problem... (Which I solved with a adapter turning off and on).

The most persistent error is the first one.

Since my car doesn't have a CAN system, I don't think that removing the R04 resistor would solve something. I just want to connect with my Engine.

Do you have some hint about what's going on?

Hi Carlos,
I'll answer in English so other people can understand what we are talking about, ok?

To read Uno FLEX on MultiECU scan, which vehicle do you select on the list?

I didn't find UnoFlex, nor another car that uses IAW 4AFB injection. So, I dont know what to do. May you help-me?

Cara, nao existe nenhum carro com a injeção 4AFB na lista.

Somente esse: Magneti Marelli IAW 4AF/4EF/59F/5AF Injection (Outside EU version)

ou esse

Magneti Marelli IAW 4AF/4EF/59F/5AF EOBD Injection

----------------------

There is no car with 4AFB injection on list.


Only this: Magneti Marelli IAW 4AF/4EF/59F/5AF Injection (Outside EU version)

or this

Magneti Marelli IAW 4AF/4EF/59F/5AF EOBD Injection

Ola amigo, IAW 4AF, é este o 4AFB, entrra em PALIO 1.0 8 válvulas 4AF/ e faça a leitura, sem problema. Ou seja 4AF= 4AFB.

Eu acho que este adaptador made in china está com algum problema. Tentei em vários carros, inclusive o Palio e ele acusa que o tempo expirou, para que eu cheque os ajustes e tente novamente.

Vou testar com outro adaptador.

----
I think my "Made in China" adapter is broken or something like that. I tried with other cars, including Palio 1.0 8V and the MCE says the time for connection is over, check you serial port settings and thry again.

I'll try another Bluetooth or USB adapter and try again.
