The Ostrich is what allows real time changes. I am currently running it on my Legend. The Ostrich takes the place of the external chip and emulates it. It's usually located externally to the ECU but it could probably be de-cased and installed inside of the ECU. Updates to the running engine are done in tunerpro and can either take effect immediately or multiple changes can be made and uploaded at once. The ostrich can take the place of the chip 100% as it's NVRAM. I've thoroughly tested it - any parameter can be changed within the ECU while the engine is running and the change is noticeable instantly.The serial port is actually quite simple. The TX and RX lines directly from the processor are routed to a communications header on the circuit board. You use a TTL-RS232-USB adapter cable and most importantly a custom written serial communications program. Without this custom program, there wont be anyway to communicate with the ECU. The ECUs stock datalogging protocols aren't understood - if they even exist.-Matt
