Neil, Depending on which year you have you can do this two ways. If you have the distributor version (older) You can use any of several simple electronic ignition boxes. Run a simple collapsing field coil and a small plug gap. As a variant you can use some of the aftermarket coil on plug coils. The original Powersport ran a simple Mallory optically triggered electronic ignition. Less than $80.00 at the auto parts store, and the Mazda original Crank angle sensor. (distributor) No high tension leads just a cap, and several multi-lead motorcycle coils. As simple as it gets. You can also get crank (eshaft) triggered basic electronic ignition. Or change over a distributor type to a crank triggered if it has hall effect pickups by doing your own trigger wheel. Bill Jepson
Now I am confused!! Let me start again and where I am coming from is
the everyday builder that may consider a rotary over a Lyc.
Price and time will dictate in most cases. Lets start with a second
hand Lyc $30,000 That gives "wriggle room" on a rotary of say $15 -
20,000 ready to go.
$10,000 for an redrive and ECU does not leave much especially if it is a
single rotor.
I really like Lynn's suggestion of fixed ignition together with a Rotec
carby, Carby $600 USD and fuel is mainly done together with the ability
to control mixture via the carby.
THat leaves ignition NO matter how I look at it with any sort of of
ECU it takes little to get to say $2000 -- if you have some idea about
computers -- I don't!
What is actually necessary with a simple ignition? MY choice in order
is Spark and timing. RPM, A/F ratio, Engine and oil temp and
pressure , Battery voltage. Then whatever turns you on as anything else
is not critical to flight or engine health. I realise that the sky is
the limit here but all cost money to be balanced against the Rotary vs
the Lyc.
Suggestions?? Remember I am computer illiterate. I prefer to say I was
born too early rather than I am totally stupid!! Price will sway people
to a rotary rather than "lovely" gadgetry that cost a lot of money.
