It's a precise microcontroller running 4 injectors in the conventinonal PFI location based upon MAP,RPM and a few other inputs.
Since it's programmed to only ramp in fuel above 260kpa and 6000rpm, it ONLY injects during homegenous rich mode. Adding up to 30% of fuel load upstream, it overcomes the hurdle of the injection window of DI.
I think changing the injectors would create more hassle than it's worth. There are more than 600 fuel tables alone.
Besides the fuel limit doesnt result an a blown motor. The cars goes "diesel" with soot when you "overrun" the fuel system. A phenomenon I like far better then running an PFI motor out to it's limit.
The main reason Im interested in the v6 over the V8 is that it has the same DI system form the solstice Ive put sooooo much time in with. hundreds & hundreds of pulls on my dyno, and and equal number of reflashes.

Secondary rail sounds great - that is a lot different than the hobbs switch triggered fogger that most people refer to in this situation. A piggy-back setup like that sounds perfect.
How much power you getting out of the Solstice with this setup?
