Proform 850 dialing it in closer

well i got my data logger to work. o2 and rpm.
Have no clue how to post it up here in a proper format.
Do they make a TPS that hooks to a Holley carb????
Map sensor? where would i install that.
Are you using LogWorks software to read the datalog?
LW can only save in file formats such its own and csv (comma limited text file that can be imported into most spread sheets).
If you can display the log graphicly in logworks, then use a screen capture to save and share it.
Most DOS and windows operating systems have some sort of screen capture. The paste to a graphics program and save and name it as a jpg or png or gif.

On my newer computers (past 10 years) I've mostly used the freeware IRFAN View for screen capture and also marking up. It has some bulk file options which work but requires time to figure out. I use XnView (also free) and MS Paint but not so much for what we're discussing.

What is the horizontal axis? Time every x seconds I assume?

And where is the shift?
If its over your finger then the trend is different than if its in the middle.
The fact that its trending lean at the top (12ish to 12.9) suggests too much air correction.
I'm sure you know what I really think this shows.
