Please post an actual useful log from ME7L

PID trims?

Post by: fgtskofd on May 13, 2016, 05:09:04 AM
PID trims?

going to adjust KFLDIMX to  95% flat settings on the top line


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 14, 2016, 11:43:43 AM
that did it  :)


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: vwaudiguy on May 14, 2016, 01:58:46 PM
Was it originally set to 97.5% across the same line you changed? You stated something to this effect in the first post.


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 14, 2016, 02:11:32 PM
Yea I just left n75 duty to where it was and set KFLDIMX to a flat 95 percent along the top line, according to s4 wiki if ldrxn is flat so should the top line of this table, if that makes sense?

Logs.

Post by: fgtskofd on May 14, 2016, 02:42:32 PM
I don't have any my laptop had an accident this evening...... but as I mentioned above setting this cured the long WOT boost surge


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 14, 2016, 02:46:58 PM
In the "log" at the start where it started surging is where this pid regulator map had been adjusted to 70-80ish so I'm assuming it must have been surging with out the 3" dp, tip and filter mods ...
This file I had was a generic stage one


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 15, 2016, 06:46:46 AM
Oh well now the surging has gone on to part load boost at 50 percent will get some logs today


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 15, 2016, 10:44:39 AM
so i took off 10 percent on the n75 duty and that seam to calm it down a little in 60 percent from 2500 to 4000 ish

Please obey forum rules.

Do not post xls files, they're worthless for use in ecuxplot

Post the original csvs.

sorry i dont use this plot software ?

iv used me7 and then copy the data from the data view ?


Title: Re: 1.8t n75 duty cycle fluctuations

I have no idea what you are asking.

Post the original .csv


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 15, 2016, 12:08:53 PM
ok .csv


Title: Re: 1.8t n75 duty cycle fluctuations

That is not the original .csv


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 15, 2016, 12:12:07 PM
yes its the original data,and has not been modified


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: nyet on May 15, 2016, 12:15:26 PM
yes its the original data,and has not been modified

original "data" IS NOT THE ORIGINAL FILE.

It is missing all of the headers. Do not export .csv from .xls, do not copy/paste into excel.

Post the actual .csv file that your logging software generates directly.

all i can find to that result is my output log


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: nyet on May 15, 2016, 12:28:38 PM
That is not the right file either, and you aren't logging nearly enough variables.


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: nyet on May 15, 2016, 12:31:54 PM
Also, please read the various logging howto guides. You aren't logging nearly enough things


Title: Re: 1.8t n75 duty cycle fluctuations
Post by: fgtskofd on May 15, 2016, 12:37:51 PM
i normally just keep the session view open and use the software to look at my results, not handy for sharing i know

ok yes i do log lots more but i wasn't sure that all the other info was needed for trouble shooting n75 duty ?

im fairly happy now that the WOT has been fixed, i dont normally cruse at 50 percent all the way up to the red line

varoius pid variables, i limiter, etc.

In particular, troubleshooting part throttle can be tricky.
