Pricing on 360s that came from the factory with manual transmissions has gone full ludicrous. I stumbled on a '17 GTC4Lusso for sale locally and I've always wanted a V12 so I stopped by the dealer to check it out. Car wasn't there but when I mentioned what I had to trade, the dude was immediately on the phone with the owner, who has been driving it himself. We arranged to meet at his storage area about 15 minutes away so I cleaned the car up, hopped in an .... crank, crank, crank. No start. I've owned the car for almost 16 years and it's never failed to start.
I think it's mad at me. 🙂
Anyway, I'm deep into the intricacies of Bosch/Ferrari engine management. Since it has 2 MAFs, it has two ECUs and essentially runs as two coordinated 4 cylinder engines. The left side ECU is the master so at least I can concentrate on that one.
So far, I found a blown fuse that (confusingly) powers the interior lights, door lights, and ... the OBD2 port. That did nothing to fix the car but did confirm that both ECUs are alive. I've confirmed that the fuel pump is priming. I bought a 'noid' kit that's used to check if fuel injectors are getting triggered but I have to pull the fuel rail to access the connectors so that's on the back burner for now.
It turns out that there are multiple 12V inputs to the ECU so it's possible for it to be responsive to OBD2 but not actually run the car, so that's cool.
