i have this problem with previously locked ecu on my new car and i cannot read or write to the ecu at all, have searched all over and tried everthing i can think of, have been through all the checks as above, voltage and so on, any suggestions anyone??? would like to be able to work through this one?

thanks

 

I have since fixed these problems by moving to 1.29A. Then I recently ran into an issue where no matter what I did when I opened ECUFlash, it would keep all the buttons grayed out. I found out that I had to remove the FTDI drivers and reinstall ECUFlash and that fixed it. When detecting the Tactrix cable there should be two "drivers loading" instances. With the FTDI still installed, no matter how many times I removed and reinstalled ECUFlash and then deleted the cable, it would only load one instance. Hope this helps someone

 

if that worked, where can i download an older version please??
