ROM dump request (A4TC401L)

ROM dump request (A4TC401L)

Postby qoncept » Tue Mar 07, 2006 6:15 pm

I'm looking for an unaltered dump of a A4TC401L (or A4TC400L) ROM to flash to my buddy's car before we tune it. Anyone have one?
Thanks!

what does that number represent? how would I find it on mine? and what are you using to dump the memory onto the ECU?

I have an 02 USDM WRX wagon if that helps

The newest I have for that car is A4TC300L. If you find it, please post it.

Colby, that ROM is from his car.. wish I could find one newer, but no luck so far.

You can use ECUFlash to dump your image, open it in hex editor and look at the address 0x200. There is a string there that represents the ROM revision.

Edit: Does anyone know what happens when you unmarry an AccessPort? Will it use whatever Cobb's revision is as a basemap or restore the original image?

Good question, I hadn't thought of that.

Does the Cobb crap actually backup the stock rom to an internal eeprom so that during the unmarrying process it can restore the original properly? I think it must...anyone?

I think I remember someone on the sccaforums saying it didn't back up the original image and just replaced it with whatever Cobb used, but 1) I can't remember for sure, 2) it could have been wrong.

No, you are right - it just overwrites the user's image with the stock image stored in the unit, so you can end up with a different ROM version than you had originally.
