Starting on defining logger definitions for the MSS52. Unfortunately i dont have a running car to test it in, however i've defined a few example sensors as an initial test - the only 2 im confident actually work are battery voltage and engine speed.

I welcome all others to test/contribute wherever possible to get the logger working correctly.

Attached is a listing of the DS2 commands that i've located on the internet.

Hi guys,

Well first of all great job for doing those definitions, thanks!!

My mss52 isnt the same version( I have version 2100 according to my hex editor) so I will reflash with your files to be on the same version.


Quick question, it seems if I try to open the full read with the xml definition it does not work ? Only partial read is supported with the xml ?



Thanks

Partial is all that is needed for tuning as it covers all the calibration stuff.

Dont need to tune the full flash for that stuff.

It was my understanding that I needed the full flash to get rid of ews and dtc's. If I remember correctly it was like that with ms43 no ?


Thanks for your support.

Ews delete is covered in the partial.
There is very little you will need to change in the full flash.

Are you sure? I never heard of 2100 DME version. The version number is there 211321001601D409, not there 211321001601D409.

I'm IN to work it out and test it with you.

updated definitions on my github.
Items are either * or **.
If you mix parameters starting with both * and ** then logging speed will be reduced.
