I'm trying to wrap up a 2 year project that uses 6 PIC processors communicating via UART, has USB connectivity, talks with an automobile's OBD II connector, controls fuel and ignition timing, manipulates a few sensors to recalibrate values due to external changes, controls an HHO system (which would be the "changes"), and has several laptop screens to do the tuning. Forgive me if I try to swim through it before asking questions when I'm stumped. Wanna help???
