  • That's because it's not really OBD-II. Also do note that for older Mercs, you need to use the 38-pin connector under the hood. It's a proprietary diagnostics connector, as they didn't implement all the diagnostic stuff for the 16-pin DLC connector. No reason they couldn't, though. They probably just wanted to be special.

  • Okay, a solution to your power issue would be using the Accessory line for the Jeeputer and all that gear, and then have the Jeeputer switch the ON line on when you try to start it, and have it switch off on secondary press. Also, you could monitor RPM to see if the engine have ignited yet, and have it automatically handle ignition.
    Also, the keypad is in a kinda cramped position...
    Apart from that, neat!
