I also posted this on Facebook and was told to post this here:
Looking to get a little further understanding before digging into my Honda VF500 project.
I think already know how to get a crank signal (Swapping a ignition pulse wheel from a 1987+ VFR750 will give me a 12 -1 wheel.) So I think that is figured out.
I also will keep the whole wasted spark system since it works. Using a Detonator EMS dual channel ignition control module on the dumb coils.
Throttle bodies I will work out, but most likely will use ones from an Arctic Cat as I think I can adapt them to work the easiest along with them having a location for an injector already. Obviously will have to custom do linkage, and fuel rails.
Fuel supply I think I can use an external fuel pump and return style regulator after I get a hose connection welded on the tank.
I have some questions about the following:
-I believe I will run the injectors in pairs same as the coil pairings, will this work/be fine as I won't have any cam information?
-This engine has a slightly weird firing order (1 - 90 degrees - 4 - 270 degrees - 3 - 90 degrees - 2 - 270 degrees - 1 again). This can be tuned for by using oddfire angles in the software?
- Would I use a TPS from a single throttle body or would it just be easier to have the MAP sensor tied to all 4 throttle bodies for that input information? A user on Facebook suggested that I use the TPS on one of the Throttle bodies instead of MAP, I'm guessing this should be fine as long as the TB's are synced?
-Could I use one of the existing pulse generators with a VR conditioner to get the information from the crank? Or should this sensor be swapped?
-Would the UA4C be the best board for my project?
Hopefully I don't seem too clueless as I tried to do a bunch of research before posting here. Thanks in advance! I'm aware this is not a cost effective modification and is more or less for me to continue educating myself while having fun.
