Ah. DDL files are time-based Datalogger Files from the IDS that show the results of continuous requests for certain PIDS. The IDS can record a few seconds of data at a time, or be configured to start logging by a trigger 'event' such as a certain PID going into a certain range.

I tried to open that file by associating it with one of my sessions (rename the file) and opening it. I'm a little new to this part of the IDS, so the fact that it came up with no data could just as well be me.

Most of this stuff is not ASCII, so that fact that we see anything at all in wordpad is because some of it is ASCII. So a Hex editor might show more info.



GEAR is PID 0x11B3 and appears in this instance to be read from the PCM (as opposed to some cars that have a separate TCM for the Transmission - like the ZF 6-Speed Gearboxes).

SBDS_CONV_643 and SBDS_CONV_285 are scaling/offset converters. A value of 2 = 1st gear, 4 = 2nd gear, 6 = 3rd gear etc

There is more ASCII in that file though. Enough to see the PID and Scaling used for each. Further down I see:
