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

Assuming that you are using the initialization jumper that you know that you need, my guess is that your voltage is just too low. I had an issue like that before. I shut off all my accessories and drove the car around for 5 minutes or so to get the voltage back up, and then reflashed. I had a lightweight battery in the car so I had some issues when it was cold out.

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
