I have elm327 that worked fine with all cars, until I tried to connect to Giulia body to make proxy alignment. I get this message.
What interface to buy that works with high speed?
ECU, airbag etc. I can connect fine.
Reading CAN configuration data ...
Interface too slow. Try to configure as ELM 327 1.3/1.4/1.4b/2.1 (High Speed)!
