I am looking for a 2004 WRX ECU. Yesterday, I was flashing my car with my Tactrix cable and half way through I knocked the USB cable out of the computer. I did and incomplete flash and now my ECU is not responding. Anyone selling a "WORKING" ECU or know how to fix the problem?

 

if its your only car and your stuck i have an 02 you can borrow till you can find one for sale. yes it will work. just have to flash a stock 02 map on it since it has a map on it for a vf39 and sti injectors. LMK

 

Holy Smokes! I would love to borrow your ecu. I do have another car but for Jesus sakes, it does not have air conditioning. OMG it was so hot today. But yah, awesome I'll pm ya. Thanks

 

I also have a used 02 wrx ecu you could purchase, really, any 02-05 wrx ecu will do the exact same thing. Nothing changed. Mine also has a different map on it currently so you would have to reflash a stock map, lmk.
