What I do mean is whether ALL the code resides in EPROM or not.

Do you mean you have the text PRINTED ON the CPU chip inside those three ECU's, or that you have the actual software (I doubt it)? > wont do you much good > they are complex and non transferable to one another Then you must mean the firmware programmed into the EPROM chip of each ECU. Then of course they're non transferable to one another, the hardware is different. > the digifant program is massive and I susspect has some ODB 1 or 2 software > that was never incorperated into the van Yup, it added ignition control to the Digijet Fuel injection only.
