1. Why take the Hall signal off the advance control unit (located in passenger footwell)? Why not just take the signal right from the distributor and eliminate the advance control unit altogether? This would seem to improve the reliability of the overall system.
2. There are two options for getting the Hall signal into MS, depending on the sensor setup. Did I get it right (in the diagram) for the Alfa V6 regarding MS pins 24 and 25?
3. Just checking, but you don't use the tach signal from the ignition coil for anything?
4. The only mods to the MS board are shorting X11 to XG1? Perhaps I already did this when I went to fuel only MSnS.
5. Any problems with overheating the bosch module with this arrangement. I'm reading all the cautions at msefi.com and am a little concerned.
6. Please let me know if you think the diagram is correct. If not, let me know, I'll fix it and repost the correct diagram for others to use.
Thanks,
