reflashing ECU back to stock
Hello folks,
I'm looking to buy an X in great shape, that has had a mystery reflash (dongle has gone missing), for a great price.
The car drives well unless you wail on it then it overboosts and enters some kind of limp mode. It has a nice turbo-back exhaust in the trunk.
Engine compression is good, interior and paint are in great shape.
I need to reflash it back to stock to pass CA smog.
How do I do this?
Thanks in advance.

You need Ecuflash, a tactrix cable, and a stock ROM. Or take it to a sho pthat has though things and have them flash it to stock. Or tune it to pass smog..

Thanks.
So I just need to buy their OpenPort 2.0 gizmo, and OBD extension cable?
When you say I need a "stock ROM", do you mean I need to solder in a stock ROM chip? Or do you mean I need the stock ROM file to upload into the car?
Cheers.

The Accessport didn't come with the car. Indeed Tactrix said it was locked.
Is it not possible to borrow someone's Accessport to marry it, return to stock, then unmarry it?

Thanks!
I looked over the procedure, and it looks fairly straightforward.
My question is regarding the step "Load up your 'Last Known Good ROM'".
If I am running ECUFlash for the first time on an unknown ECU, is it just a matter of downloading the right factory ROM and loading that up instead?

access to the correct pins on the ecu. These pins wouldnt be available to you on an ecu that is still wired into the car. You could maybe do it with the ecu in the car if you made the right kind of harness, but one wrong pin and you could fry the ecu hardware, so ultimately the time to remove the ecu is a small price to pay for ensuring you dont screw it up.
