Thanks for the reply, the problem turned out to be that 12V has to be applied to the ECU in DBC cars, so I modified the OBDII cable end, pins 16 (12v) to go to Pin 11 which goes to the ECU with a soldered switch, and this fixed the issue. Thanks for everyone's help

Thank you for the quick reply Morrias. I will try the Tactrix drivers with ecuflash 1.29a. I've done some reading and it seems people have been successful with the same car I have and DBC cars in general, so I'll keep after it and post a solution in here when I find it.

I know I'm going to get beat up for this question, but I bought the same cable from Alpha-Bid and can get it to read/log but can't get it to flash at all. My guess is because the car i'm trying to flash is a 05 WRX 2.0 Turbo. It's not Drive-by-Wire like the Legacy/STI's so it requires the 12volt write block http://www.tactrix.com/images/0405_WRX_init_connector_smwm.JPG. My flash issue is ECUflash fails to write because Programming voltage is too low. Example from my logs: -reading ecu programming voltage -programming voltage is 4.28 volts -programming voltage is out of range! Does anyone know for sure this won't work for Drive-by-cable / WRX ECU's or should work etc. Due to the difficulty and price with the openport/tactrix cables I was hoping this would work for me as well. Morrias, what drivers did you use? Lasted FTDI (worked) or the one's on alpha-bids link (didn't work for me), or the ECUflash 1.29a drivers? Thank you
