I might be able to pick up an Aquamist 2d system for a relatively decent price but am not sure how useful it will be on an FD. I did a lot of searching here but could not determine if it is possible for the FiA2 injection amplifier in this kit to determine an overall injector duty cycle. As far as I can tell, it can not. If not, is there another option to drive the injector in this kit?

 

I'm in a similar situation and my understanding is:

The FIA2 can use the secondaries only (or primaries). Richard at AQ has also made a "Summer" for rotary engines that can run off of both the primary and secondary. I have been in contact with Richard and he says the Summer can be ordered directly from him for $150 + $18 shipping.

Thanks for the link. The sentence

is interesting. I'll need to do some calculations, but it is not clear to me that the extra 13% would offer a significant tuning advantage.
