I have a APR flashed ECU in my 01 S4.
Can I read it or will it brick?
If I can read it can I load each map / calibration for each program and see the difference between each one? For self educational purposes..
Yes I have searched for an answer but no clear answers..
Is it flashed or on a riser?
If on a riser you can bootmode read it.
If flashed you may be able to read it w/o bootmode
It will likely not brick
APR usually obscures their maps and makes extensive ASM changes. It is unlikely you'll be able to figure any of it out.
It is a total waste of effort. Go back to stock, start again.
