if your playing with ignition maps only/ an ex temp gauge and wideband a/f monitor is needed. dyno is for swapping hardware and building customized fuel mapping.
without hardware swaps like exhaust etc there is just no need.
a dyno is used for evaluating what affects any changes make to the performance of an engine. regardless of what those changes are. some people dynotest just to show they make 0.3% more power by using ceramic bearings...
an ignition curve can have a major impact on performance with or without pipes.
how an airfuel sensor can have any bearing on determining correct ignition timing, iunno.
and how exactly would i adjust the fuel map on a steam engine if that was what i happened to be testing on the dyno that day?
maybe the same way i would tweak the mixture on a 32kv wound brushless motor, seeing as thats been on a dyno to see if the extra gain in power was worth the extra current draw due to rewinding with two less turns...
all this nonsense about "this retard curve is the ducks guts because i say so and it felt smoother and got up a hill 2km/h faster than yesterday" is BS. i want definitive results, not the propaganda spat out by a salesman or someone trying to prove what they cant.
but i do agree that an exhaust is a much better upgrade than some ignition circuit!
basic circuit works well enough for me. just some people are willing to pay for gimmicks if theyre convinced enough...
