Scatter plot info

[nathanhardy]

Hi I thought this might be a good post to start maybe the mods can lock it if it starts having some good info, also I'll change the title to something better suited.. Info welcome, so I know nothing about scatter plots but I'd love for that to change what I'm looking do here for the forum is have a post that gives the info needed to setup them up then explains what you'd look for in the plot to determine problem. I think it would be a nice reference list to maybe add to the manuals down the road!

I know I'm not the best At asking question but is there any info out there on this?

Google is your friend for this question. Also check out http://www.miataturbo.net/
They are big fans of MS over there and have lots of scatter plot specific info.

Here is the most basic scatter plots off one of the blown motors I tune. This is most like the Speed-Density fuel map.

The trick to understanding scatter plots is plotting lots of data. It is almost impossible to have too much data.

I do think that scatterplots could provide some info regarding issues during tuning, but the info is not enough or not specific enough to really make use of it correctly.

There is no one way to view EFI data. I have been doing this stuff for about 15 years now and scatter plots is now the first place I go to see what a motor is doing.
