I'm planning on picking up a spare 8D0----557P ECU from a 98 Tip car.

Has anyone successfully recoded it from Tip to a manual? I've read conflicting reports in the archives.

Thanks.

Which engine code? Car? Model year?

I'll be buying a spare ECU from a 98 A4 1.8T 8d0---557P Quattro Tip. I would like to recode it to the Manual version. I found an older post with the coding option (which I believe is the same as mine 06201).

I have to wait until I get the other 1998 557P ECU but I am guessing it will be a 06051.

I assume the "20" and "05" are the important parameters. I just hope it will accept the coding change.

...so try to get the engine code please, or the complete part number of both ecu's.

Digit@lex

Both engine codes are AEB.

...if it is not working, this will be the point to request here and i will have a closer look at it.

the softcode...

My current Manual Quattro ECU is...

Controller: 8D0 907 557 P
Component: 1.8L R4/5VT MOTR HS D07
Coding: 06201

The older TIP Quattro ECU was...

Controller: 8D0 907 557 P
Component: 1.8L R4/5VT MOTR AT D02
Coding: 06251

I successfully recoded it so now it is

Controller: 8D0 907 557 P
Component: 1.8L R4/5VT MOTR HS <B>D02</B>
Coding: 06201

The <B>D02</B> is my only question. Is that a revision number for the firmware? Should I be concerned with that? This will be my backup ECU. I will have it socketed so I can transfer my custom chip/encryption board to it.

Thanks.

.. if i were you i would use the d02 for tuning and hold the d07 for backup stuff...
