IDA Pro now supports 8x196 (www.datarescue.com).  It will cost
$200 though... highly recommended if you can afford it.
Otherwise, search the archives on how to write your own.

You could buy CarComp's software.  www.carcomp.com.

Considering the VW Passat has the same engine available and chips
are becoming available in the $200 range, do you really want
to do this?
