[Diy_efi] BMW Motronic 1.3 table editing?

[JS Nord]

Hello,

New arriver to the list here.  Thanks for having me - great resource.

My interest is in being able to modify the fuel and timing maps for used in 
the BMW E34 535i, Bosch motronic version 1.3.  I'd like to be able to do to 
help tune out a modified engine that includes a displacement increase and 
cam shaft change (no forced induction)

I'm curious if anyone on the list has experiance in understanding the 
mapping structure associated with this version of Motronic.

I'm also curious if anyone has experiance in using this tool from Atlantis 
software that seems to have the ability to edit the motronic tables 
http://www.atlantisconsultingllc.com/atlantis.php?page=Motronic%20Editor 
Best case would be someone who's used this tool on the BMW 1.3 motronic and 
has the offsets for all the tables with some real world experiance on how 
well this tool works.

Anyone have any thoughts on past discussions or projects in this area that 
might help me get started?

Cheers!
