Working with 360Trev, I have have removed the two Immobilizer modules from a 2003 F1 Modena. It is a joy not to be burdened by the necessity to press the key fob if I fail to start the car within the 120 second rule imposed by this system. To have the ECUs re-flashed required removal of both ECUs. The driver side was straightforward; the passenger side was quite difficult because of the various hoses that blocked access to the 10 mm bolts securing this ECU to the chassis. Both ECUs were shipped to Trevor's USA affiliate. The turnaround time was less than 48 hours. Before reinstalling the ECUs, I opened the fuse/relay compartment from behind the driver's seat and removed both immobilizer modules. I also performed the starter relay bypass modification. This procedure is well documented on FerrariChat. To accomplish this required cutting two wires from one of the immobilizer connectors and joining them together. After reconnecting the battery, the vehicle started up without any difficulty whatsoever. Although I am obliged to use the key to lock/unlock the vehicle, I will address a new remote locking system at some time in the future. My thanks to Trevor for the invaluable service he has rendered to the Ferrari community in decoding the Bosch mapping of the ECUs. I am grateful for his efforts as I am no longer tethered to equipment that could fail at any time and for which there may be no spare parts available. For example, Ricambi does not show replacement ECUs for a 2003 F1 Modena. This is undoubtedly a sign that replacement electronics is becoming serious issue.
