Hi friends. I need some help if any of you can share some logs of a 1.8T engine with DBC M383 and / or M592 ECUs, I need a datalog in csv format of measuring block #2 of an OEM engine, preferably OEM ECU (un-chipped) with preferably OEM turbo. Some logs at  normal operating temperature and normal operation behavior like idle, normal cruising, high boost and if possible a WOT pass could be great. Do not forget to indicate from what car/ecu is log coming from and vacuum values at idle and how much max boost is.
I really appreciate your help if you can friends.

From stock m5.9.2 97 AEB, few posts down has load info

Max boost is about 7 psi,  vacuum at idle -17 in hg

Have some other stuff if this isn't what you need.

Nice info, but can you share whole log in CSV format?. Also what is the part number of the ECU? how do you associate your wideband AFR log with ECU log?
Thanks,

To get the AF I guesstimate time offset between starting logworks and vcds. I import both into excel and create a new time column for the AF with time offset.  I then use vlookup functions to match AF with the vcds timestamps.  Sounds harder than it is but does take some time to fine tune the time offset. Easy to see when correct when data is plotted.

ECU is 558m.

Nice trick Placebo. Then you look for the VCDS timestamps in air-fuel log and take AFR value for that moment. It is useful if offset between both logs are as closer or minimum as possible.

ECUxPlot will correlate wideband with ecu logs if you have rpm data on the wideband log.

I didn't know that. Really thanks for the tip. I need to test it.

I too will look into ECUxPlot but  my wideband does not include rpm >:( .  In case anyone is interested, my spreadsheet for how I match my wideband is included.  I also calculate boost in my spreadsheets based upon this guy's method http://www.audiworld.com/forums/vag-com-discussion-51/calculating-boost-maf-rate-numbers-engine-speed-2580862/ (http://www.audiworld.com/forums/vag-com-discussion-51/calculating-boost-maf-rate-numbers-engine-speed-2580862/).  I use it because it appears close (within a psi or so) to my boost gauge readings when running stock or chipped.

ECUxPlot can be adapted to read any kind of csv based log file.

Curios, how do people get rpm data with their wideband, I am using an innovate LC-2 but it only logs time with A/F.  Wonder if people pick up the rpm signal and feed it into the LC-2 somehow.

I have do it, adding a Innovate SSI-4 interface. But it can be done with any datalog box.

Also about boost calculation I have using a formula posted in other forum may years ago --> http://forums.vwvortex.com/showthread.php?4389484-How-To-Log-Boost&p=61588154&viewfull=1#post61588154 (http://forums.vwvortex.com/showthread.php?4389484-How-To-Log-Boost&p=61588154&viewfull=1#post61588154).

Here is an excel sheet with some of my calculations.

Here the associated AFR summary log.

If you want ECUxPlot to support Logworks, you're going to need to post csvs, not some bullshit useless non-portable MS crap :)

Nyet, thanks a lot for your help. Here is the csv version of the Logworks log.

Thanks :)

I will work on it time permitting.

My log works would only show the first two columns  :(.  Eliotroyano, your excel file is a masterpiece, I need to study it to figure out how you do the hp.  toque etc. calcs.

I'd rather you spend time learning java and sending ECUxPlot patches rather than wasting time with a spreadsheet, which is not an easy tool to distribute in any useful fashion.

try this

Basically I was adding info and functions to that excel spreadsheet, trying to make easier datalogging task of these ECUs. Also Nyet comment is really true. I was done that tool for personal usage, it is really easy to understand, but could be not so flexible or portable to use it.  Anyway you got the idea, but it can be modified or done in a much better way.

Anyone can share another M38x or M592 logs? It could be nice to have some others to compare.
Thanks friends.
