Ok that's definitely doable, but how to you guys figure out what changes you need? Like what percentage to scale by, more than just oh this looks high ill bring it down some. Using excel and ECUxplot I wasn't able to figure out a way to get my logged values and mlhfm to line up correctly. Only a polynomial trend line. Take the derivative possibly?
I also have matlab but don't have too too much experience with it, besides some basic engineering examples.

Ballpark will be fine. Just do a lot of logging and generate 3d heatmap of load vs rpm vs mean trim to adjust KFKHFM
should be close enough.
If you see a simple linear trend you can fix in MLHFM or KRKTE, do it there first, then relog.

I agree. Get the MAF dialed in right first.
How do you plot the data as a 3d heat map? I've looked online and no one seems to have any info on it. I've attached a .csv with a lot of data, and about half way down I have some data pulled to the side which I'm pretty sure is relevant. Anyone have a data sheet I could use or something like that? |

I made a bunch of custom scripts a while back send it to gnuplot... I assume there is an easier way to do it in excel but i'm no Excel expert :/ I'd love to add it to ECUxPlot but the plotting library I am using doesn't have heatmaps. |

So you have these scripts for gnuplot your saying? I'm open to use any program if I can find one that is... |

That would be great. What do you recommend to analyze the data now? Because most available graphs to me don't really make sense of anything |

Any news on this? And also I can't seem to get my ltft's to turn off. Not sure how to find NOLRA in my file being that its a single number and also have heard conflicting info on if changing it really does anything in the ME7.5 ecus. Also have heard to pull the sai relay which I believe I did but this didn't work either, got the check engine light for it but still the ltft's are on. Ideas/help? |

You did a wideband conversion to CH ecu but uploaded your old P file? I downloaded a stock CH with your SW version from here: http://nefariousmotorsports.com/forum/index.php?topic=5251.msg50026#msg50026and scaled it, using a-maZers  tool and your given 60 95 inner diameter. outcome is the attached file. This file and your stock injectors/stock pressure should give good fuel trims. |

Starting from this you will be able to change your fueling:
what is your stock injector size and fuel pressure?
