Hello,

how can we setup up the stock 13b-rew ignition system, where primary ignition is using one coil with wasted spark for both rotors, and trailing is using 2 coils with direct fire?

regards

This base map is not mine, and I have very little Ecumaster Rotary experience but this is a base map for an FD3S from Ecumaster USA’s database. It has the ignition coils setup like factory FD

Isn’t this a emu black file? \*.emub?

can someone from ecumaster team confirm that this is correct and that wasted spark for leading ignition will work when assigning output IGN 1 to both rotors in sequential mode?

Rx7 FD stock ignition system is wasted spark for leading ignition and direct fire for trailing.

whoops yes, forgot what section I was in.

They were developing a EMU Pro 13B PNP kit, but I don’t see that map available for download just yet. I’d shoot them an email

This is the way to set it up. Both ignitions moment will be done on the same coil. Coils has the 2 spark plugs connected so they both will fire.
