in regards to gearing, and feel free to ignore it if i should only be talking about smoothing. but in my atx (where there is never anything really near 1:1) the higher the gear, the "bumpier" the graph gets. this was even at the dyno day where a quick 2nd gear pull happened to be on with my final pull. seen it on a few dyno's now. this would mostly me do the fact, if what i'm reading is correct and it sounds that way, since it takes longer to go through the revs you see a bit more variance....more chance to show those small variances? the #'s tend to not vary that much, but the look of the graph does....am i understanding that part correctly?
Dyno chart smoothing? Does it make a difference? See for yourself...

I read comments on here once in a while about how FocusSport likes to use a lot of smoothing on their dyno charts. Or how there is a big difference in smoothing from 3 to 5. Or from 1 to 5. Or from...you get the idea.
So why don't we just take a look for ourselves?

Horsepower and Torque can change slightly with the different settings, but its not anything major. A dyno chart from a well sorted car with a good hardware and software package will look good at any setting. A chart from a car with a not so well sorted hardware and software package will look like it needs help at any setting.
So there it is, laid out flat for you to see. Now you can see for yourself how much of a difference each setting makes.
