2013 Subaru Legacy 2.5i Limited 2.5L (FB25) (TR580)

Greetings everyone.

I've got a quick question. I've never performed software updates on a Subaru vehicle. Is the process similar to other vehicles? Do you have to buy an update CD from Subaru, or do you just go to the Subaru TIS website and program vehicle as if you would a GM or other vehicle?

The NASTF site has a link to Subaru programming info. Sounds like you have to purchase a cd for $75.00. It's updated four times a year. nastf​.​org

Thanks for the heads up. I was just looking at NASTF, and it appears I'll be getting a CD.

When you purchase the DVD from Subaru it has all of the current flashes from the beginning of time until now and you can flash multiple vehicles using the DVD so the next time a Subaru comes in and needs an update as long as the updates for the TSB is before the date of the DVD you got you can flash that vehicle.

nastf​.​org/i4a/pages/inde… Has the phone number to call, I had a friend order it from his local Subaru and it took a long time to get it, when I called the direct Line I got the disc in 3 days to Hawaii.

We called the dealer, and they gave us a song & dance about it being proprietary information not available to the public. So we called the phone number & all is good.

I just wanted to let you know something I just learned about flashing Subaru’s. When you hook up the clean battery source you want to set it for 12.9 DC or less as there have been some issues with failed flashes if the voltage goes higher than that

Thanks Kabel, I'll keep that in mind. Don't want to brick a module due to a failed flash.
