I was originally planning to upgrade the Yellow 993 272 hp engine to varioram specs, that's why I bought a used but working Varioram 96 motronic together with the varioram Air intake.
But then I changed my plans and I decided to go for a fully original engine rebuild: the engine parts are there ready to be reassembled, I am just trying to understand if I must go searching for another DME Motronic (the one for the '95 ROW 272 hp) or I can somehow use the Varioram Motronic I already have on the shelf.
Only later I am pointing to build a spicy engine, based on another motorblock (possibly a 993) and other parts taken from different donors (GT3 crankshaft, oil pump and air intake and so on): but first of all I want to put the car back on the street, naked and superlight, but matching number.

If the varioram is from a ROW car and if your harness is up-to-date, it should work.
Still, best to ask Bill Verburg since I don't ever recall a Euro owner inquring about this mod.

yes, the DME Motronic is from a German '96 Car and I would like to eventually use it on an italian 95 (272hp) engine. (my idea was more or less this way: if it works with more stuff - the varioram system - it could possibly work with less stuff to manage)

Why not go with using the vram and 96 ecu? You get the benefit of
1. keeping the numbers original using the original block with the vin
2. the upgrade of a better "factory" intake with the vram setup?

Be aware the Varioram ECU has the donor car's VIN burned into its involatile memory so when someone scans it, it won't match the car putting it into.
Honestly I dont know if its original Motronic is rescuable/reusable.
Another possibility could be install the varioram and its unit together with the stuff needed and meanwhile search for the 272hp unit or for someone able to repair its original unit

My understanding is yes, however, the vehicle-specific chip is soldered onto the board in a '96. Later years I understand it is removable. I suppose someone knows how to socket the '96 circuit board but getting it programmed with a different VIN by an aftermarket tuner will probably be very expensive.
My point being if you are looking for originality, keep the controller that came with the car.

2. To modify '96 DME ECM a circuit board modification is required, i.e. a daughter-board is added.
3. The '97&'98 DME ECM's can be flashed, but require the chip to be un-soldered for flashing and then re-soldered.

Can one download from the '97-'98 chip original program and keep it for future use or just keep the old chip as is and get a new chip to flash with the new program?
Could one solder a chip socket into the board of a '97-'98 and then just plug the chip in after the reflash? It could make future reflashing a simpler affair.

Your remarks are accurate for NA cars, but not for Euro cars. The Euro cars had obd1 varioram into 1996 and relied on the 1995 style dme with a removable chip.
The 1995 dme can be easily modified to perform like a euro dme, but given the access the OP has to the european market I would source a slightly newer varioram dme. You dont need to run a new wire from the DME to the fuse box in the engine compartment. Just move the pins around at the DME end and at the fuse box end. Sounds like a lot of effort, but for what you get in return its worth it. The car sounds better and performs better, plus that big ole alloy intake manifold looks the bees knees compared to the ugly plastic one.
