Currently collecting components but the circuit diagram is just about complete. The only thing I'm worried about is that just about every vehicle has a different wiring scheme when it comes to positive/negative inputs. I will need a way to easily configure these in the circuit and in the code to make the device as flexible as possible. Newer vehicles also rely heavily on the CAN bus and will not be properly supported. Most vehicles after 2001 will require a separate ignition-bypass module. My prototype vehicle is a 2001 Honda CG2, which features a fuel-injector immobilizer via RFID in the key. Two options are using a transponder and blank programmed key (switched on and off by the VORP module) or a separate, third party module such as Blade.
