<A HREF="http://forums.swedespeed.com/zerothread?id=118952" TARGET="_blank">Reference thread</A><p>So, I was having some alarming performance issues (R r<B>ela</B>ted, not R r<B>a</B>ted folks <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0">). I needed to have a look-see at the control module codes. I needed the ipd softloader. I don't own one, so much thanks to Stoyan for taking a ride with his setup <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"><p>When we got back, we looked at the data and the codes. If you've worked with Exel you know that graphing is pretty cool for certain stuff. I thought this was a stuff. <- Purposeful, totally.<p>I decided to put together a little write-up on how to graph the output from the ipd softloader data logger. So, I imagine my first shot with these pics is going to be pretty bad, but here goes nothing (I will be saving it out seperately too):<p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/1.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/2.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/3.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/4.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/5.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/6.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/6_5.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/7.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/8.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/9.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/10.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/11.jpg" BORDER="0"><p><IMG SRC="http://i208.photobucket.com/albums/bb11/giovi28vr6/Elfinito.jpg" BORDER="0"><p>This image is representative of <B>65 rows</B> of spreadsheet data, in the <B>boost column</B>.

And if you have some cool graphs of your own runs, post them up.

Brilliant. Excellent tutorial. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <br>I'll have to try this.<br>Great job! Scott

Re: Graphing the output of ipd Softloader Data Logging Software (Lightspeed)

Thanks! I can take better screen-caps at work, so I'm just glad the text is approaching visible for most people. Let's see some pulls! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

Re: Graphing the output of ipd Softloader Data Logging Software (JoeLvo)

I take a data log run about once a month and compare the data to see if I'm losing any boost. It's a good way to keep an eye on the TCV as well as compare seasonal effects (among others). The Bell FMIC keeps it pretty steady though. <p>Thanks for taking the time to show others how to do this. I have found it very helpful for some time now. Can't wait to see the changes once I go to Stage 2.

Thanks for this, I'd never known how to turn delimited files into columns without opening it as a text file (where the text to columns thing pops up automatically). <p>I always throw RPM on there with the boost on a secondary axis, as it seems to be the most relevant cross-reference. Like this:<p><IMG SRC="http://www.slaptardcentral.com/gallery/files/6/5th_gear_full_throttle_pull_before_and_after_flash.jpg" BORDER="0"><p>To do that, I just right click on the data line and select "format data series", and then under the axis tab select "secondary axis". <p>I just wish excel allowed 3 or 4 axes. It'd be nice to be able to graph MPH, boost pressure, and RPM all at once. Once you had those 3 scales, you could plot a/f ratio on the same scale as boost, and both pedal position and charge air temp on the same scale as MPH. Although dividing RPM by 100 allows it to also be plotted on the 0-100 scale as well.

Nice before & after on that boost/rpm graph <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">
