I guess its just EPROM and should hold data sitting on the shelf for years if not subjected to ESD (static or electrical discharges).

Without pulling one apart Ijust don't know, and before anyone suggests it. NO I'm not going to pull the one in my bikeapart to find out. Basides any chips in there are likely to have the kind of Delphi part numbers on them that make no sense to anyone outside of Delphi.
imboden,
I can relate to that, at half the cost the PCIII is much more attractive to anyone on a budget, especially if it can and will do the job quite nicely.

RE: ECM Fried
I never thought about the ECM shelf life issue. so, I shot off on email to ThunderMax. I figured they know the details of ECM's inside out. Their response, " the shelf life is unlimited for the ECM. No power is necessary unless mounted on the bike."
Which makes sense if in fact EEPROMs are used....

RE: ECM Fried
Agreed, well that answers that question. They have to be using a much better/faster grade of EPROM's these days. Older ones that I am more familiar with were not very good in the access speed area and would be at best only marginally suitable for todays higher speed processors.
I'm only making a semi-educated guess but EPROM's are not the fastest thing around but if they are using themjust to store the data and maps, itmakes sense. That way they would have a nearly unlimited shelf life.
The datacouldbe downloaded into some high speed ram chips to actually run the bikes systems.
Oh well, someday I'll get a decent set of documents to explainhow theyare made and work a little better.
Thanks
