wolf3d to tewblog datalog converter

So, since the wolf datalog reviewing is so awful, I made a little script to convert it to tewblog format.

I have my techedge wbo2 device 5v out wired to the wolf so the data being logged is all coming from the wolf.

Tell me that this isn't neat =]

Can now do matrix analysis of the wolf log files with accurate AFRs =]

anyway

Code:

#!/bin/bash



count=0



if [ ! $1 ];then exit;fi

if [ ! $2 ];then exit;fi



cat $1 | grep \\. | awk -F, '{print  ",_" ($14 * 2 + 9) - (($14 * 2 + 9) % .01) ",_" $4 ",_0,_" $6 ",_" $14 ",_" $5 ",_" $9 ",_" $12 }' | grep -v ',_,_,' > $1.1

TIME, Gasoline AFR, RPM, Manifold Pressure (kPa/psi), Boost (psi), o2 (volts), Load, Duty Cycle, Air Temp (c), Error' > $2





for a in `cat $1.1`

        do

                echo -n `echo $count \* .001 | bc `

                echo $a

                count=$[$count+67]



done | sed 's/_/ /g' | sed 's/$/, 0, /g' >> $2

rm $1.1

first arg is input file, second is output file.

Here is a screen shot, showing duty cycle, load band, rpm, afr, air temp (c), and boost (as wolf sees it, this is always higher than what other map sensors see I notice)

This is just reving it in my driveway, I'm going to replace this img with one of an actual pull shortly.

Very nice. So how does this differ from the one Michael Smith did? Did you use the wolf v4 software to do the datalogging or Micheal Smiths datalogger?

:shocking: :shocking: yippy another Linux man!! Good stuff nyt :)

Can a program be written to read directly from the wolf with the tewblog? Rather than datalogging with wolf or Michaels datalogger than converting over?

Now that would be awesome!

that would be tough. You'd have to do some virtual serial devices and have a program read from the wolf and output it to the virtual serial port that tewblog is reading from. Datalogging from the wolf software is trivial, doesn't really matter either way.

Now to either replace the Y pipe in my exhaust or run the wastegate back into it so I can have stable boost.

how do you get the 5volt input to datalog?? I had a look at one of my excel datalog files and there doesn't seem to be a column for the input voltages.

I'm contemplating getting a PLX SMAFR and hooking the 5volt output to the wolf and datalogging that. However i'm unsure if i should go the R-300 unit instead.

ah ok so the wolf o2 input can read up to 5volts.
Cheers for that.
