As Rick says. Calibrating the DME circumnavigates the learning curve.
Its easy to check - just disconnect the battery for a couple of minutes, reconnect and start the car. You will feel the tickover slightly lumpy and (if you drive it) the performance is not quite as crisp as the engine management system adjusts to fuel octane rating / ambient air temps/ throttle body positioning etc. Leaving the ignition on for the +/- 60 seconds allows the DME to revert back to what it was.
At least that's how I understand it.....
