Q: How to select a board?
|
||||
|
||||
A: History shows that fully assembled boards are the safest way to start. History shows
|
||||
that 80% of the kits are never assembled. As of March 2020 we have many assembled microRusEfi and
|
||||
very remaining old stock assembled Frankenso. New fabrication of assembled Frankenso is
|
||||
currently not planned.
|
||||
|
||||
Q: What else matters?
|
||||
|
||||
A: Types and total count of crank and camshaft positions sensors is the next
|
||||
important question. microRusEfi unfortunately only supports one VR shaft input maximum with two inputs total.
|
||||
|
||||
Frankenso supports up to 2 VR or 2 Hall shaft position sensors. Prometheus supports TBD. Proteus supports TBD.
