"Failsafe" gauge which measures your flow and you teach it what expected flow is at different MAF or MAP rates is, so it will trigger an alarm if the flow rate falls out of the expected range(either too much or too little). Can also take action based on this alarm, like trigger the CEL (not sure if my particular car has an ECU wire somewhere that can be grounded to trigger that actually) so in theory it could trigger the CEL which runs a different timing map with lots of base timing pulled or something along those lines.

I'd love to just throw it on but the failsafe stuff seems smart.
