Hello Admir85

Your ELM interface hath no bridge resistor with the Multiecuscan problems.

Alfa exactly what you have?
Which controls can not you read?
Since your ECU is not read via CAN. may be with you only a setting error
or you installed the wrong driver
Try this one

Remove the red resistor and let this place open
it is the interface with CAN bus capable Multiecuscan

i've the same elm 327 mini and it worked right on ford fiesta and alfa 147 1.6 120c, but not on fiat punto (188) 1.9 jtd (I tested with torque first )... now I removed the R04 121 but it not work on punto and alfa..
sorry for my bad english i'm italian

Hello

The ECU of the Alfa 147 will not read about CAB bus.
The ECU of the Grande Punto but already

Therefore, the resistance problem can only occur when the Grande Punto ECU

You may not remove any resistor !!
Because there are so many different boards and it is not always the R04 of causing this problem.

Meanwhile, here many boards have been mapped, is yours??

Or take a picture and I control this
The connection problem is often a setting error

Alfa 156 1.9 16v

I installed those drivers,but it didn't help. Every time it says "connection timeout"
Changed settings about speed,latency etc... but it didn't help.

Connects normal with usb elm 327 cable,bluetooth tried on two different computers,one with xp other win7,nothing happens,always same error...

Hello Admir85

Put your first interface into the OBD socket
then into the PC

Then press settings (F9) / Interfaces / search interfaces

What is displayed??

It finds elm 327 1.3+ bluetooth on COM3,or on different com if I plug in usb adapter into different usb port.
I can connect with digimoto and modiag tools,but just not with fiatecuscan or multiecuscan.

I do it because to my fiat punto (188) don't worked correctly..the RPM were wrong ..what i can do??
however I repaired the R04 but no change !!
i bought this http://www.ebay.it/itm/230990579095?ssP ... 1423.l2649

what is the best OBD to read all the car? or that read the punto 188 (not grande punto but the second series)

this is better?? http://www.ebay.it/itm/310692542834?ssP ... 1423.l2649

thank you very much

edit: for the connection I used torque it search automatically
this is mine obd

Hello Marinozacc

For your Punto 188 of the ECU is not read via CAN bus.
Therefore, R04 may have played a role.

The specification for the speed is wrong??
What more??

Can you read out and clear fault codes??

Greetings Eddy

[marinozacc]

when the OBD were original it read ONLY rpm (wrong) on punto.. now nothing

ahah sory and the cooling at 218 °C ....XD

can you tell me a good OBD elm?
