A4RN1000 is an sti7 and the A4RN2000 is an sti8.
Just wondering..........
I have flashed mine (Originally A4RG060Q (AG820 2591)) with the A4RN1000 (AG820 2592) because it had extra tables in, but was wondering if the revisions in the later models had more fixes but the same 16bit ecu and therefore could take a 'newer' map.
The A4RN2000 is listed as AH992 fix, whatever that means
Cheers
