Logger done! - SOURCE AVAILABLE

Postby realwomble » Sat Jun 04, 2005 1:26 pm

File data logger for WRX using SSM protocol (not ODB-2). Quick e.g. about 9 samples per second when logging 6 parameters per sample.

Update - v1.03 - See README in ZIP file for details.

(ECU_V1.02.ZIP ATTACHED TO THE END OF THIS POST)

See the README file in the ZIP file for more usage details.

Quick start (after connecting to car)

Code: Select all
  ECU.EXE <comport#> INFO


Choose which parameters from the list you want to log, and

Code: Select all
  ECU.EXE <comport#> LOG filename <param1> <param2> ....


... where <param#> is the short name for a variable in the INFO command output - e.g. RPM or SPEED. Can specify interval per parameter (e.g. every sample, every 100 cycles) - see README for details.

SOURCES are included in the ZIP. License for source is GPL. If you change / add / link to this code, post your changes back here. Main areas needing input are (1) more ECU information and (2) GUI if anyone is interested.

Win32 C code. Project from vs.net. For other vers, just create a "win32 console project" and drop in all the files.

Have fun, let me know about gross bugs or inaccuracies!

v1.02 6/6/05

- Fix calculation error for AFR1 Lambda
- "PSI" param was "absolute manifold pressure", which is wrong. Changed this to MANABS, and changed relative manifold pressure to "BOOST".
- Change time to seconds not ms.
- Change accuracy to 2 decimal places not 3.

1.03 6/7

- Add READMEM option
- Fix units on TPS.

Hi,

The link to the sources just downloads the .exe-file, could you update the link to point to the sources?

live logging?

Postby loscooby2 » Wed Jun 08, 2005 10:54 pm

Hi,

I want to use the logger in my car since I already have a pc and a 7" touchscreen built in to my dash it makes good sence to have some params logged on the screen live instead of going to a logfile...

Have you thought of adding support for a stream-output in addition to the file-log output?

I think my problem could be that I have an NA model.

Glad its working for you. Moving house right now, so won't be able to do much for a couple of weeks.

LOAD moves per revision, I haven't had time to trakc it down yet. Can you PM me the output of the ECU n INFO command for your car?

Thanks.

womble --

Great bit of code, thanks for distributing source.

I'm using your stuff as a reference to make some rapid prototypes of realtime 3D data displays... hope to post some screenshots or sample video in the next few days.
