    After clicking case the re-learn procedure requires that you raise the engine revs to 4500-5000rpm (over about 1-2 seconds) until you hear the fuel cut momentarily. Then let off the throttle and allow the engine to return to normal idle speed. Then ignition off for 15-30 seconds to allow the ECM to save the learned data.

    Nothing that you will notice. EFILive sends the CASE learn command to the vehicle. The vehicle then waits for the operator to perform the CASE learn RPM increase.
