That´s really not easy. You have to switch the processor from internal rom to 
external rom. Read the internal Rom from the processor and then fit a 27c256 
eprom into the blank space on the pcb. Now it´s very easy to modify the ecu 
using an emulator. 

I have the information how to switch the processor from internal rom to an 
external one but I don´t know which processor is inside. Having a look at the 
ecu it shouldn´t be a problem to find the processor type and read the rom. 

I guess Chris Smith from Racelogic is still on this list (Hi Chris!) and I think 
he should know about that.

If you´re just looking for a cost effective performance increase I´d suggest the 
Superchips conversion. They show an interesting 16 hp gain on the rolling road 
(using high octane fuel).
