The guy that writes the latest code for MSnS-E is a rotor head and has
it running with the CAS ( which has been the hold up for awhile with the
MS system.. the V3.0 board incorporates an lm1815 signal conditioner for
running one set of crank triggers and has a development area for putting
a second lm1815 in fr the 2nd set of  triggers. ( trailing & leading now
)..

I don't suppose he has it working with the RX8 single sensor
system does he? Kind of easy to put a pic in there dedicated
to the RX8 system that puts out pseudo 2nd gen dual pulses :)
Throw a little hardware at the problem :)

Hi Paul;

I believe someone recently got an RX8 running on Megasquirt - haven't
followed that thread as closely.

A lot of information can be found at:
 http://www.rx7club.com

under the megasquirt forum
 RX-7 Owners Club > Tech and Performance > Engine Management Forum >
Megasquirt Forum

The other hotbed is:
 http://www.msefi.com/
MegaSquirt EFI Forum Index -> MegaSquirtnSpark -> MegaSquirt 'n Spark -E


At last check, only the Version 2.2 megasquirt boards were tested with
rotary ignition.
A new rotary board facilites ignition.
Search for "Error*'s MSnS_E Daughter Board"

Also do a search on "rx-8" and "rotary ignition" for an 18 page thread.


Cheers
