The v3 summer needs primary and secondary signal. Trigger point is bsed on the the sum of the IDC signal. The summer can also be triuggered by 0-5V or a voltage-based MAP sensor signal.
The summer is designed IDC to "sum" two idc signals, boost cannot influence the summed output. The RX7 summer is an "add-on" to solve the unusual stepped sequence of the primary and secondary injectors.
We believe the idc signal contains all the information of multiple sensors on the engine. tracking this signal is a good representation of all loads.
As I have mentioned before. It you only need to inejctor water above 25% IDC, you don't need it, just read the idc signal from the secondary injector.

my car isn't a drag car.. just the oposite if anything it will be more geared twards track / auto-x . I want to run windshield fluid not straight water , for protection against knock , and cleaning / cooling purposes
I already have an aftermarket ECU , so if the deal is its going rich in the lower RPM's I can lean it out if needed . I have a wideband so I can see if its going to rich . the summer thing looks great .. but I'm tapped atm.. I want to get the car running after its running I can work on making the car perfect.
do I NEEED to wire it to the secondary injector ? will it caause the car to sputter to something ? because to do that it will be a big pain. damnit.. I'm just pissed off atm LOL I think its better to just tap the ECU harness.
and to re iterate what I understood .. at 100% flow of the secondary injector's the aquamist will be throwing out more water , then it would be at 100% of the primary?
