Iterative Label calculation for Bosch DME

Post by GLX »

Hello,

Is it possible to have iterative calculations feature in he next version of TunerPro.

I mean approach native for any Bosch DME when axis legend table contains no pure data but decrement from previous item.

For example:

Example of a 2D map starting at 49F4

049F0 38 50 50 80 3A 04 05 23 23 9C 42 02 0A 9C FF 00
04A00 CD 00 9A 00 4D 00 38 06 1F 1F 20 1E 1F 51 80 60

map byte description:
3A - the X parameter name, in fact the 8051 sram location
04 - the X map size
05 23 23 9C - value of X axis points calculated as follows
x0: 0x100 - 9c - 23 - 23 - 05
x1: 0x100 - 9c - 23 - 23
x2: 0x100 - 9c - 23
x3: 0x100 - 9c
it's a delta format, the x3 value can not be less then x2 value
42 - the Y param name
02 - the Y size
0A 9C - Y axis values (100-9C-0A) (100-9C)

FF 00 CD 00 9A 00 4D 00 - the Z values in the order
x0y0 x0y1 x1y0 x1y1 x2y0 x2y1 x3y0 x3y1
If this feature will be implemented to many people from Bosch world will become in TunerPro :)

Thank you in advance.

I'd like to also put my request in for this one please...

That example structure shown is just one technique in Bosch DME I have seen - there are other schemes that I have not unlocked yet.

Other Bosch weirdness is that I have found some maps manually that things like WinOLS doesn't. These are old Bosch Motronic 2.x.x systems.

There was an 'Atlantis' package available to do this for some Bosch systems on Porsche vehicles, but I have never managed to get it functional.

Cheers,

Paul

I got nowhere with the Atlantis package...

I ended up writing something in PHP that parses the Motronic files - looking for the labels I know/care about... Just a few steps away from having that create an XDF file that can be ingested directly on TunerPro.
