[stefancaromov]

Thanks a lot for the info. Any price about obdkey, cos in that site you gave me i didnt found ?

Hi

OBDkey BT = 125 €

OBDkey usb = 112 €

It's just that at this price
which is then equal to the CANtie interface can buy incl MES software.

Hi there I have this interface and tried connecting to Punto mk1 1.6 elx 90 it connects tells you the voltage and then disconnects again within 10 seconds this is the interface can you help me I want to read the can on ecu. If I buy a modified elm 327 will this work

Hello

Your ELM requires no modification since there is no bridge resistor
I suspect that you are using an old or the wrong driver.
Try this

Otherwise, controlling again all the settings such as Latency Time
and Com port

Hey guys!

Great work sorting out all of these faulty adapters!

I see a few pages back a fellow posted an image of a red PCB Elm adapter but did not supply good enough piccies. Well, I have the same adapter and they seem to be quite common on ebay these days.

Please PLEASE help!

I can connect to the engine etc, but when I attempt connect to the SERVICE etc option it requested a Yellow Adapter 3 cable (which I then plug in), but then cannot connect.

I assume I have the same resistor/termination problem, however my PCB is laid out differently to the others.

Please find photos of the PCB in question.

Thanks in advance guys.

Hello abraxxious

Remove the white plug please Holder with 8 contacts
including I suspect the bridge resistance.

Your pictures must not be so large, only the resolution should be high
Not so blurred

Greetings Eddy



Edit: It should be around this ELM?
then remove the yellow-marked resistor.
