I just purchased the Xcessive LIM, as you all know it has 4 injector bungs cast into the LIM itself. Sure, I know you may plug 2 of them and run a total of 4 injectors just as Mazda intended to do so. However, I am building a high horsepower car. I plan on running 2 850cc Primary's and 4 1300cc or 1680cc. Either way, I play on running a total of 6 injectors. The question is, can I batch fire my 4 secondaries with the PFC?

Thanks in Advance!

I would think you would have to wire them so they open exactly as the other secondaries and tune them as one unit. Probably would have to set the secondary's to 2600cc, for 2x1300cc each, and just tune from there.

 

I would not do this without something like the FJO injector driver that's been discussed recently. But they have a 4-injector version which shouldn't be too hard to wire up like this.

 

Since you will be running 6 injectors, keep the 550s for the primaries. This will make your idle adjustment so much easier. Take the secondary wiring to fire a FJO driver for 4 injectors.
