Is it possible erase ecu coding when removing engine ?

[durfA4]

**I think I might have reset my computer to stock programing (if not cleared the Unitronics file at least the coding of the ecu) The requested boost of 12psi, this code, and a strange thing the gauge cluster (prior to install the clock in the tach did not display the date, after reassembly the the date I'd visible all the time). Cats are auto speed 3"downpipes with high flow cats andno code before turbo replacement

What do you guys think?

You can't erase the flash unless you run a tool like my free software. The ECU coding won't reset unless you run a tool like VAG-COM to reset it.

Use VAG-COM to read the coding from your instrument cluster, and ECU, and we can tell you if it is correct.

Also, contact Unitronics and ask them if they have put any custom code in the ECU flash that may disable the performance tune if the ECU is removed or something.

That was my thought. How easy your software to use, Is it more raw code or like dsmlink with adjustable setting for tweaking files. And could I reflash over my uni file if I wanted to?

Currently my software only lets you read or write to your ECU. It does not currently support editing. You can read your unitronic file, and then reflash over it, unless unitronic blocked reading.
