Can I do several pulls in one log and it would still register correctly in the program?

Yes, it can do this, but then you might get weird averaging where you are spooling up.   You can mess with the spool filter to account for this.  I would really just do one pull in 3rd gear from 2,000rpm to redline for each dc.

Okay, I'm really excited to try out this tool.
I've always hated messing with the boost PID  Tongue

Although my PID was fine and worked, I still tried this.
Everything is perfect. Resulting KFLDRL drives awesome. Very easy stuff.
Only 0-40 duty logs are annoying to do cause car's so slow then.

EDIT:

Huge respect and thanks to the creator!

Indeed ^

Massive massive kudos SB-GLI.

This'll be default stage 2.5 tuning in due course I'm sure ;-)

Maybe I am using it wrong, but the generated kfldrl is completely flat, 0 10 20 etc

no matter what logs I use, I tried with yours and same result

Upload your file, but if you are getting a flat drl with my logs, you're not doing something right.   First "load" the files which will fill out the grid on the main form with pressure by rpm and dc, and with that filled in click "generate"

never mind, I was not seeing the load button  Grin  Tongue

another question, on IMX we fill with duty to achive those pressures?

The tool works based on the concepts that were described in the first post on this thread.  Understand those, and you'll know how to use the tool. 

Hint: With this method, KFLDIMX basically converts the KFLDRL axis into pressure.

Also, went through the thread - LDDIMX/LDDIMN can give you problems, might want to get rid of some of that.
Generally overshoot is not the fault of the I maximum or the pre-control, if the pre-control is calculated correctly.
At lower revs it can be because you are not loading engine enough at low revs when generating the map (don't have dyno), at all revs it is usually problem with too aggressive P or too little D.

Those logs won't work very well without accel pedal in them.  The tool filters out points less than 80% pedal.   If you don't have accel pedal in the log, it takes every point.
