- What functionality would i need to touch presumably?
This is the primary question before any effective dev work can proceed. There are many concepts to ITB fueling that appear to 'work', but duplicating an existing method may not be the best path. I think this is one reason @noisymime is currently running ITBs on his MX-5 (and quite happily I hear), in order to gain some perspectives on the best path to take at this point for Speeduino.
If you want to take a shot at using a dedicated ITB control system; you could duplicate the "MS" style as a test reference, or create a multiple MAP system, or IMAP/EMAP, or one of several switching or blended load sources, etc. Examples of the last one could be 1) hard-switching of load source from TPS to MAP at adjustable points in RPM or load. Another could be blending the load sources as percentages across RPM, e.g.:
There are many potential options. I would try some of the ITB features already in Speeduino to get some reference experience. Pick your path with research ideas or a flip of the coin, and take a shot!
