All the VAG-COM cables I saw on ebay say they're for Audi's and Volkwagen's. I haven't seen an Subie cables.

That is because they are all originally for Volkswagen. For this application we are adapting it to work with the Subaru ECU.

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

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.
