I should have kept my massive FMIC. Oh well, they're cheap.

look into it a lot. if it's only a 5 degree split (that's what it looks like from your post) that may be enough split for 6-8psi, but that's pushing it, especially if you have very coarse fuel control. the trailing plugs need to fire ~10* behind the leadings.
what exactly do you mean your trailing ignition isn't doing much with your direct fire? it needs to be doing a lot. trailing ignition is very important. you have to ignite the other end of the long rotary combustion chamber, and it needs to happen at a specific time --~10-12* after the leadings fire. feel free to bring up any valid arguments for this.
i'm not trying to be a smartass here. i'm only posing these questions to help you, so do a lot of research and post a good reply
