Do the TR and 348 use the same Cat temp ECUs for the slow down lights?
No. The 348 uses 142581. The TR uses 141037 (later TR's). Very early TR ( < 76444) uses 61402500. But we shan't discuss that one because it bears no semblance of reality.
It depends which injection system the 348 has 2.5 or 2.7. The 141037 ecu is used on 1990 TR and all 348/Mondial T with Bosch 2.5 injection. The 142581 is used on only 348/Mondial T with Bosch 2.7 injection.
Esteemed 348 owners. Can anyone help build out a thread on how to pull and seal the CAT ECU with silicone to prevent moisture from destroying these $400 parts? I"ve started the below based on excerpts from my348.com and would appreciate any additional steps, images and general advice. As i'm a newbie DIYer so please be specific - any overkill is much appreciated: -Purchase a $3 tube of Permatex black silicon. -Drive the car to help evaporate any moisture that has already penetrated the CAT ecu. -Disconnect the battery. J-ack up the rear (where do i place the jack? Do i use two jacks on each jack point?) -Remove both rear wheels. -Remove both inner fender liners. -Unbolt, unplug and pull out both of the exhaust ECUs.(is this easy to do?) -Seal them up with the Permatex black silicon(where do i put the silicon?) -Be sure to seal everything except the electrical wires. Sealing it should keep moisture from getting inside the $400 CAT ECUs. (can someone provide more pictures?) (is silicone the best sealant to use or is there a lighter/less permanent sealant?)

I'm no expert, but can't you get to it from the engine bay side? https://www.ferrarichat.com/forum/posts/135843275/ Another view: https://www.***********.com/threads/348-slow-down-lights-cat-ecus.7901/
