I'll now expose more of my native ignorance: are the EPROMS you're referring to different from the Autothority chips that it currently has? I'm assuming so.

Bear in mind that you require the tester to have the earlier type of lead that car a 12way rectangular plug, not the later round 19 pin type.
My "Spanner" is available with both types, and I am sure someone on Rennlist has a tester and 12way plug lead.

Rod:
You can borrow my JDS Spanner. I would have run it on that car before Brian and I sent it off had I known it had the updated EPROM.
Send me a PM with your address.
