S4/S5 tuning options

[Scott.T]

Hi guys,
I'm thinking of coming back to the Audi brand and jumping into a S4 or S5 sportsack and was wondering what tuning options are available.
Last time I was around here the later S4/S5 ECU was not yet cracked and there was alot of nervousness surrounding Audi's new found ability to detect a mapped ECU this invalidating warranty.
As a result if this I believe a number of tuners were switching to tuning box technology instead of flashing the ECU. Such that it could be removed prior to service/diagnosis etc.

Any info would be useful......

MRC is a popular choice...

Just treated the S4 to an MRC Stage 2 package

Dippy's S5

If you Google "Audi TD1" you'll see what the deal is with the warranty flag.

Hi Scotty
Yes I'm aware of the TD1 as that' what I was referring too above.
I noted previously that even big tuners were moving over to tuning modules.
Is the MRC a module or flash ?

As far as I know the big tuners are still flashing. DTUK have a tuning box.

CREC engines fitted in cars from mid 2014 use the SIMOS 16 ECU. Many but not all tuners are able to remap it via OBD port. I know that the following in the UK have confirmed that they can (alphabetic order):
APR
Celtic
MRC
REVO
Unicorn

There may be others I don't know about. For example AmD - I think they might but I haven't confirmed.

Remaps can easily be detected by reading the ECU flash status, so there is always a risk that a tuned car will be flagged TD1.
"pay to play"...

Having had a box (A3 TDi) and a flash (S5) tune, I'd go the flash tune every time...
