Quick query:
A dyno manufacturer is claiming that their machines correct for temp, i.e. will give the same output figures regardless of temp, a test vehicle will show the same power whether tested at cold or hot days.
Without a MAF is this possible?
For example, pre-det due to high temps, how can a dyno pick that up and correct? Surely engine power response in relation to intake temp is hardly linear (or an easy calc) - especially when you take into account forced induction, compund charging, intercooling, etc.?
Or am I about to be amazed at modern dyno equipment?
