We have a repair facility here that does component level repair. Since I've
never tried to open the case on the ECU don't know how hard that is but if
it's not difficult and the circuit board can be accessed, I can easily
replace the eprom in the ECU. Since our Dutch friend says they replaced the
eprom, sounds like it can be done to me, otherwise there would be yet
another ECU. Eproms depending on type are not very expensive, getting a
master eprom or the code to put on the eprom is obviously the first step. No
master eprom or new "96" eprom code, then forget it. Bob B. (hoping there
actually is a new eprom and someone can get it)

But the EPROM's are soddered on and sealed in to the ECU,
right? You'd have to replace the entire ECU - which is big
bucks.
