I have ecuflash and the taxtrix cable. The taxtrix cable plugs rights in and my laptop reads it and my light on the tarmac starts to flash but this appears..

[15:46:25.487] interface close
[15:46:25.497] unable to connect to vehicle interface

What is going on? I have been stuck with a 50 Trim turbo tune on my stock turbo for two weeks now. My car is slow and it waste hella gas..

 

uninstall ecuflash and reinstall it. i borrowed a friends cable and tried to connect but i couldnt. my acd lights flashed as well when using his cable. i erased ecuflash and reinstalled it, and it worked. make sure u save your maps and your rom file if it has any hacks.

what version of ecuflash are you using by the way. i hear 1.39 has bugs. try erasing and reinstalling an older version.
