There not like 1:1 car engines were there computer tuned and automatically adjust to weather changes. Even something as simple as a fly wheel will alter the results of a test. Best testing i can think of is on the track doing some head to head.
Now I dont have nearly the experience you guys have cause I am new to this hobby. But I think the dyno can improve ones knowledge of any given engines possible powerband and people with experience can benefit greatly from it I'm sure, whereas the average basher might not. Considering that the majority of us will either not use this information or will not have a dyno done on our engines. I think what we will find is that with these new ONCAR measuring devices (nomadio, spektrum whatever..) become more prevalent and certainly more advanced and robust (with time) useful for ONTRACK tuning because the stress on the vehicle will be real stress allowing for greater tuning knowledge allowing for educated decisions on what to mod or not mod.
For instance I use a Dynanite .12SPD, I will not change engines until I have throughly discovered everything that can be done to maximize it's performance. I see so many threads that state, " I use this engine, is there a better one?" or guys switching engines like flipping a switch. I plan in the future to utilize a shop to mod a brand new dynamite and compare it to an unmodded brand new dynamite. Hopefully when I can afford to do this, these oncar measuring systems will be able to measure a great deal more than they do now allowing for accurate performance comparisons ( Heat, speed(at the flywheel and the wheels), voltage, g-force(weight transfer), mb suspension load etc.) coupled with weather conditions. Technology will get better and cheaper. Those who utilize it will better off than those who don't. Just my .02
