Will the recoding program for the auto tranny on the A8/S8 work for a 97A4 auto?
 

Anybody try this yet ?<ul><li><a href="http://www.audipages.com/Tech_Articles/auto_transmission/codingtransmission.html">http://www.audipages.com/Tech_Articles/auto_transmission/codingtransmission.html</a</li></ul>

I don't think so. Doesn't work on my 99.5 A4 either.

Doesn't surprise me, transmission and its ECU are different between any A4 and A8...

Here's the basic concept of that.....
 

If your TCU is coded "2" originally, you can change it to 12, 22, 32, 112, 122, or 132. Each variation will determine certain changes, probably outlined in that link I didn't bother looking at. It holds overall line pressures higher, to enable quicker shifts, and allows the driver to "hold a shift", and doesn't shift out of first automatically.

This "mod" won't work on anything that's not tiptronic, or originally coded to "2".

Thanks Matt,...what about the part where they Mention the Non-Tip tranny ?
 

From the link ....."97 without Tiptronic
If your car does not have tiptronic, it won't hold first gear with the "sport" setting (00011 or 00012). From the factory it came with the coding of 00002, which is the stock setting for U.S. and Canada. 00001 is for the rest of the world. It appears that there is little to no difference between the two "DSP on" settings.

If the transmission is recoded to 00012 (DSP shut off U.S. and Canada), you will find that the transmission holds gears slightly longer, and learns quicker than with the stock coding. It is a slight improvement over the 00002 coding.

It will also take code 00011 (DSP shut off rest of the world). This coding makes the car more of a "European touring machine". It really makes a huge difference in the way the engine and transmission responds. It will shift at higher RPM's and downshift with much less throttle input that the 00002 or 00012 code. The transmission matches the engine speed to the driver's needs, where with the 00002 and 00012 code, the engine speed is too slow for the driver's needs."



Is it worth a try....Or am I playing with fire ?
