[s-cars] Back in an Audi (95.5 S6) - some questions

[Peter Schulz]

Jerimiah:
Don't assume.

My wife's wagon came with stock injectors, exhaust manifold, and ecu.

And an RS2 turbo.
Needless to say a bit laggy to drive.

>> First question:
>> I am trying to identify the "tuning module".  When I went and bought it I found a sticker that said "tuned by TAP" so I expected to find one of the hand written notes as listed here: http://forums.quattroworld.com/s4s6/threads/13957.phtml But I didn’t instead I found.
>> 3 BAR transducer, and 2 chips both computer labeled.  One on the same board as the transducer say: AAN LDR 5CC0 the other says AN MOT F2C5  Any idea what that chips these are?
>> 
>> Second question:
>> Any harm in switching chips, but not tubos, injectors, maniforld, wastegate sprint, etc?  I didn't think to grab the wastegate spring, and couldn't figure out how to get the manifold off. (those bolts at the bottom leave no room to turn)
>> 
>> 3rd question: how would I identify which hybrid turbo I ended up with?
>> 
>> 4th question: how would I clean the injectors, the S4 was full of varnish from sitting a long time.
>> 
>> thanks in advance.
