I don´t know. I´d be interested in one myself but I have the instruction manuals 
for two German emulators (damned expensive) and they tell some nice facts about 
mapping ECU´s. Unfortunately it´s only in German language.

I wouldn´t buy the Eprom Wizard at the moment. Either wait until the programmer 
has released a better version or contact dimensione sport at: www.dimsport.it. 
I´ve just met the guys in Italy last week at the motorshow in Bologna. They 
really have a nicely done emulator for a fair price. The Eprom Wizard can´t cope 
with:		8-bit chips including 16-bit maps
		two 8-bit chips in 16-bit format (lo/hi)
		two 8-bit chips for TDi´s (boost/fuel)
		and many more.

Furthermore you don´t have the possibility to watch the address bus with eprom 
wizard. Dimsport´s emulator shows you exactly in the map where the computer is 
working at the moment while driving on the rolling road! Furthermore dimsport 
can give you support about map and limiter locations. Unfortunately they 
don´t have their 16-bit version ready yet but they´ve told me it would be 
finished in spring 1998. But just have a look at their page...

If you don´t need a high quality win95-version you could buy the German OLS4. 
It´s only a DOS-emulator and it doesn´t show the maps on your screen, only 
dozens of numbers. But this OLS4 enables you to watch the address bus! You can 
download a demoversion from: www.evc.de (I think this address should be right, 
send an e-mail if it is not and I´ll have a look).

There are two more German companies offering emulators. One, CSW, offers really 
any features you want to have (except support!) but they charge around 18.000 
DM, that´s more than 10.000 US dollars! Another company charges 12.000 DM but I 
haven´t seen their emulator yet.

There´s one more company in Italy offering a very good emulator at a very fair 
price (5.500 DM/3.125 US$). Unfortunately they haven´t been at the show in Italy 
so I´m still waiting for their catalogues. They even offer books about 
chiptuning (italian language only). I can tell you more when I receive their 
catalogues.

I´m working on my own win95-emulator at the moment but I will not be finished 
before fall 1998!
