The Thread below is some back and forth I had with Matt at DIYAUTOTUNE. Being this is an email thread, you will want to start at the bottom and work your way up.
Matt at DIY seemed to think the larger system could accommodate Batch injection for three channels. Due to the 1300 having wasted spark. I think only three of the 4 channels would be needed. To jump to Sequential injection, Then a Crank and Cam sensor would need to be added.
I have seen posts on the Crank portion, but not on the Cam wheel. Matt at DIA had some good ideas and they have added a CAM sensor to an OHC bike in the past.
See post below.
"Hello Todd,
The Hall sensor setup can be considered a kind of crank angle sensor; the downside is, the MS2 doesn't support three separate crank sensors (two can be done, but it doesn't have enough I/O for three of them). You could replace the single tooth wheel on one sensor with something like a Ford style 36-1 pattern to control ignition.
As for sequential injection: You could drill the cam cover and use a Hall sensor to read a cam lobe or other protrusion on the cam sensor. We did that for our land speed racing car when the cam was missing a distributor gear (it was meant for a different cylinder head).
Let me know if this sounds doable.
