Hello everyone!

Firstly thanks for your help because time ago I was able to modify an old cable elm327 with your help and advices.

I am trying to have another one but I have received an strange circuit board which I have not found over here. Does anyone know it and can help me with it?

Your help would be very appreciated



Thanks in advance for your time, help and knowledge.

Hi
I just bought a similar interface (at least the main side of the board). Installed the CH304 driver on my old XP laptop.
MES connects to the car using this interface but does not show any live parameter values. Did you get yours going?
Thanks

Hello,
i have problems with connection to a fiat 500x 1.4 T-JET/MULTIAIR. I have a elm327 module 3.0 since about 10 years and never problem with the old cars.
But today i can connect to this fiat in order to clear maintenance indicator. When i connect to service/service interval reset (334), i have a execution error message. I can connect to the engine without problem
my multiecuscan version in 4.9 registered.
May be i should have a multiplexed version ?
Thanks

Hi, I am asking for help with my odb2. It only connects to the ecu for 5 seconds then crashes and disconnects in every program and application. This is obd2 "ymiot b18-3 wifi". And the car is a Fiat Bravo 2.
