= Resolved threads


In the video examples, screen shots are used to show how to find a map but how would you find them before you would know what they might look like?For example a different ecu manufacturer or different engine would have fairly different look tables i would think due to different features like flex fuel capability or a some type of vvt may be used (or not used) etc.

Around 7:47 in the video there was mention of Bosch literature. When talking about scaling factors. what type of literature is this (is it on the processor, the specific ecu, or general strategies than bosch uses when they design an ecu, etc.). Where/what would be a good way to find such literature? I am able to find some reference manuals on specific processors used in ecus but unfortunately not much else.

How do we figure out the bosch names for tables like the KFMIRL? I am guessing they are german abbreviations due to working with some bmw coding.

Edited =)

Hi Bryan, a lot of working with OLS is building up an understanding of the shapes of various maps so you can recognise them visually. We obviously can't provide this for every potential map in every processor, however there are still consistent shapes to maps even across different processors. For example a wastegate base duty table by definition is going to have the same general shape to it irrespective of which manufacturer is implementing it. However we also need to understand the logic flow of the particular processor as not all controllers will have the same maps.

With respect to the literature discussed, this is a description file which is an internal bosch document that defines the controller logic flow, maps, map addresses, axis addresses and scaling factors. This document also includes the technical german names and acronyms for the maps which is where the likes of 'KFMIRL and KFMIOP' come from. Obviously bosch don't just hand this sort of information out and it can be difficult or impossible to find for newer controllers. For older generations of controller though this sort of information is often found on chip tuning forums.
