And one more request, important to me...
Can you add HP/TQ/Accel etc calculations based on vehicle speed instead of RPMs?
The reason I am asking is that sometimes I see wandering nmot_w during WOT pulls which completely throws off the HP/TQ/Accel calculations. I've had this issue before on a different ECU/crank sensor/clutch/FW and it is back albeit in much less severe fashion.
Once you think about it, the way you do it now is actually kind of backwards as it assumes some things like that RPM signal is perfect (but it might oscillate quite heavily if the engine misfires for example and FW buffers the shocks allowing the engine to "rubber band" in respect to drive train) and rpms per mph are chosen right... Working off vfil_w would be more consistent as that's what ECU sees the tranny output shaft spinning at.

Excellent point. I've actually been meaning to do this for the reasons you've mentioned.. also not sure if you noticed, but there is some pretty serious smoothing of rpm data built in as well because i've seen the same on some cars..

Awesome, thanks! And I appreciate adding raw RPM a while ago. |

Hi Nyet,
Great bit of kit this. I was wondering if you could help me. I did look for this info but couldn't find it in print and I don't have an Audi to test the logger.
I've written a CAN-BUS logger for Volvo ME7 which seems to work nice. I'd like to output the data to CSV for easy input into your software.
Could you point me a list a list of field names it will automagically like (assuming there are some). Ideally I'd like to make the process as automatic as possible, it's easy enough to print whatever field names we need at the top of the CSV file.
FYI, the tool will be Freeware in-case you are wondering. No plans for open source at the minute though.
The variables it may log will be, rpm, gear, ait, coolant temp, egt, throttle, boost, ignition, tcv, desired boost, and both knock sensor voltages.
Cheers!
John.

Thanks, that github linky gave me an idea. Pretty much got it sorted with trial and error and a browse through the source. It's a very nice bit of software you have written there!!  |

I read in another thread there is a .kp => XDF converter somewhere in a bundle with ECUxPlot. I looked around and I'm not finding it. I know its called mapdump. Where'd ya put it?

no, it's in there. I didn't realize it was in the folder until right now because I just checked. I was looking in ECUxPlot the program.  |

I tried to open a 19MB log file in ECUxPlot but the file is a Log.xml, produced from Neflogger. Nothing happened but it took forever for nothing to happen. The program went unresponcive for a time and then when I tried to open anything it would just freeze up for a while after. Needless to say I didnt get it working. Is it possible to get log.xml files to load and be analyzed?

I have not tried to get it to work with nefmoto logs yet. It DEFINITELY does not support them  Also, it looks like the mapdump.exe is still broken. You can try to use mapdump.jar if you are very familiar with java, but if you aren't it will probably just cause headaches. I'm actually at the track (sonoma) right now, and wont be back till tues, then leaving again the week after so its unlikely i'll have time to work on either issue until nov :/ |

If I didn't PM you with the error I got from mapdump I meant to. I'll get it there eventually. Good luck at the track, thats awesome! win win win
