So I am trying to read this stock ecu on the bench.I am not having any luck with the nefmoto software tool.Any ideas what could be my issue??Ecu is powered up on bench 12vdc approx 2 amps.Immobilizer is disabled.I can connect using same cable to ecu using vcdsliter without issues.


Here is the log from the Nefmotor software:


Validated FTDI device is in dumb mode.

Been there done that.Powered pin 121 up still no dice.Changed baudrate and it appears to be working.Just weird as I'm running win7 ultimate with all the right drivers and using a recommended cable.
