Title: Communication error with ecu Post by: S4addict on July 24, 2014, 07:19:31 AM I figured this is the correct thread to post this since its communication
Proticols. I have the blue ebay cable and i took the housing off to verify That it has a ftdi chip on the board and it does. But when i try and flash read with nefmoto it gets to communicating timing And sits there which is very frustrating now i also did digging before i posted Ive tried this on 2 diffrrent b5 s4s and i get the same place each time The car is plugged into a battery charger. I downloaded the ftdi drivers and installed them And i have the com port set as 1 Also this happens if i try and logg the car through nefmoto the cable will connect But when i hit start reading under the logger i get to timing and thats its Any help is much appreciated Title: Re: Communication error with ecu Post by: ddillenger on July 24, 2014, 09:10:16 AM I figured this is the correct thread to post this since its communication Proticols.

Title: Re: Communication error with ecu Post by: S4addict on July 25, 2014, 05:21:12 AM it was the baud rate.
i didnt see that you select the baud rate to connect to the ecu. and then select it again when you go to flash read works great now Title: Re: Communication error with ecu Post by: ddillenger on July 25, 2014, 10:27:25 AM Which is why I said
