You missed Alan's point. Have you heard of a concept called phase?
The clean signal has better accuracy than the noisy one.
Or a longer integration period...
Scope traces look cheap, but they do not lie.
All stats lie to some extent and tell the story how the narrator wants it to be told. Yours especially, no doubt.
They may not tell everything, but it's better than nothing.
Actually, it could easily be worse than nothing. I have lots of scope traces that I took to prove certain things in the early days. Most of them were convincing but wrong. I know better now, better than you, too.

Sorry, whatever data he has is as credible as he is, which is not very after the parade he has put on in this thread. I hope the google rank of this thread is high, I'm sure it won't be too low, that's for sure.
Does Supras come with trailer hitch?
My R32 Skyline had a trailer hitch on it! I put it there myself. I'll ask my mate with a 500hp twin turbo supra if he has one on his, I wouldn't be surprised, though.
Have you ever driven a 600hp car?
550, 500, 400, and numerous others, the question is, at what weight? I totally understand fast cars, yes. Do you? I'm dubious.
Nothing against alans test rig and lab measurements, but this is starting to sound these things are made for test rigs and lab gasses not intended to be a tool to tune a car?
What are you smoking up there? I mean, I guess you have to burn something to keep warm, right?
and after that you put it in an engine to see how well it responds throttle changes, changing temperatures, flow velocities etc.
Fail. Finland is one of the three best educated countries in the world. My country is in that group too. What the fuck happened to you? You're ignoring the basics now. Go back and read it all again.
And if you would use mass air measurement and be aware of the fuel flow at given time, it gives a fairly good average of what the afr should be.
Not to the same precision that the devices that we are talking about do. In fact, if they did, then you'd not need these types of products at all.
But the point is that you would know the absolute measured values and the absolute accuracy from the lab test and then take it to the real world with real variables.
I have a BSc, have you ever conducted an experiment and had your conclusions and data run over with a fine tooth comb by someone with vastly more knowledge than you? It seems not.
That's true that I'm a bit odd for a Finn as I don't automatically respect/believe any authority, titles, school diplomas, am not a member in church, don't lobotomize myself with TV etc.
Sounds like you don't have those yourself. Probably jealous of those who do. I smell an internet warrior. How old are you exactly?
But I bet your experience of Finns is that you've seen Kankkunen, Mäkinen and Häkkinen speaking 'motorsport english' in TV :lol2:
Who? I lived with one for a while and have known several others over the internet for many years.
What does this mean "hell bent on being a knob for sport", seeing that for the first time.
Hell bent = intent, really wants to, is going to stop at nothing to, etc.
Knob = dick, cock, etc.
Sport = something you do for fun.
