No.....
Remember, you are setting the Alfano to '2 stroke' and thus it will measure 'every spark' which occurs once per engine revolution.
When you set it to '4 stroke', the Alfano KNOWS that most 4 strokes only fire once every OTHER revolutiuon and thus 'doubles' the counted sparks to give the engine revolution 'count'. Effectively, in '4 stroke' mode, it simply doubles the spark count to calculate the revs.
The action of 'mis-setting' the Alfano to '2 stroke' completes all the changes that you need to do. Once your've done it, if it reads 5000rpm.... you ARE revving 5000 times per minute!
The problem comes if you set it to '4 stroke' for a Honda as it will be counting the actual revs (e.g.: sparks per minute) and then DOUBLING that number so it will read 10000rm when you are only doing 5000rpm.
