Default Couple delta dash ?'s

When i use the road dyno it doesn't have the stock tire size. I have to do custom size. Why is that? And i can't save it so i have to put it in there everytime. Is there a way to save it?

Also, when i do a road dyno run or a data log how can i rename it to help me reference it? For example, rename it "first run with open loop fuel at 97%". Cause that would really help.

When i do a data log, how do i take a value like knock correction and drop it ontop of another knock correction data log? How do i take manifold relative pressure and put it on top of engine rpm to see how my boost curve is? Stuff like that. Thanks......

205-50-16 i think is the stock size. and i haven't been able to find a way to save the setting between usage. for me it holds the tire size but always resets my gearbox to uk sti and the vehicle mass to custom.

i don't see a problem with that. all the log names are based on date/time. you can rename them to anything you want.

im not sure you can over lay graphs on top of each other. but to view something like boost over engine speed you can play around in the custom 2d graph. make your boost the y axis and the engine speed the x axis. you'll have to play around with the sliders until you find the area you are looking for.

also these logs are saved as csv files. you can load them into excel and do your own graphing if you are good with excel..

Stock RE92 size is 205/55-16. If it's not there, then put it in, Save Data -> SETTINGS.DDF (or any other name that makes sense to you). When you load Road Dyno next time, just Open Data -> SETTINGS.DDF, do your run, Save Data -> mynewfile.ddf

This is ideally what the comments box on the 1st tab of road dyno and the last tab of Live Data Capture is for...

But you can name the road dyno files anything you want.

For datalogging, I make a directory first named YYYYMMDD (example: 20030723) and do all of my defog-switch-based logging into that directory with appropriate comments either in the .txt files or in my own README.txt

You can't. You can open multiple logs in separate windows and line them up, that's about all. Or, like Mike said, you can load the data into Excel, OpenOffice's spreadsheet, etc.
