Interface modding 1.3 into a 1.3U-R

Postby enash99 » Sun Jul 25, 2010 10:17 am

Hello everyone. I have been a Subie owner for many years and have had no issues with my 1.3 cable connecting to MY02-My03 and 05 STI. I am able to read/flash as well. Now I have purchased a 1992 Talon TSI. I have modified it to use a 2003 USDM Evo 8 ECU. Well ofcourse the interface is different and the cable I bought in 2006 for my Subies is only an OBDII cable, it does not have the white flash plug that is needed to flash the EVO ecu. My Question is, Looking at my friends Openport Cable that he uses to tune EVO's with he has the white flashing plug and it is connected to his openport cable with just a single wire. Is there a way that I can just mod my current cable? I dont see myself ever going back and owning an older WRX again, and I would hate to see this cable not get any use. (I know I can sell it) But is there any circut level differences other than the white flashing plug that is connected with the single wire? Can I make my current cable a 1.3U or R which ever it is. The price of the cable is $137.00

I am not trying to be cheap but since this one already works to reflash my subies, I also use it to datalog our 2000 galant as well. I just wonder can I get that plug and solder the wire into the right location and be able to use it.

When i open up ECUflash with the cable connected and then I select the EVO 8 model I get the error
"[11:55:46.215] flashing tool "mitsucan" loaded.

Is what i am looking to do possible?
