F1 Injector Answers
I never ran them with a stock cp3. I made 616hp with a Floor It stage 2 pump and 636hp with my twin pump setup, with the twin pumps we brought the pressure up a little sooner, max was still at 26,500. I am still waiting to get on a dyno with my new twins.
How will the 2s be pulling wise? I'm bout to start looking into injectors too, but I also drive my truck every day and have to pull trailers on a daily basis, sometimes 12000 pounds and up
I made over 650 hp on 1.5s glad I did not go any bigger cause I need to tow 12,000lbs 1x month and tow a 7000 boat about 20x a year my truck pulls way hard with the 1.5s and smokes very little bigger sticks are not as good for daily driving and occasional towing due to the fact they run hotter and with proper fueling smoke too strong for public highways and streets not to mention they have been known to paint your trailor black LOL
My original point was that there is still room to add more max pressure from another module and I'm confident the CP3 has a little more left in it.
I was just at Floor It today and we were playing with the latest beta software from Marco being at the shop. The way I understand it is that it is adding pressure, but controlling it to the factory maximum. So it is increasing rail pressure. Without it, I still bet your rail pressure with those injectors and a stock cp3 would not be 23k. It's only 23k, because the Smarty is adding pressure up to that limit.

Maybe I'm wrong, but it seems if the stock max RP setpoint is 24.5k (for example), and the Smarty is not increasing that setpoint, then the max RP would be about the same without it. I guess what I'm trying to say is that when you go WOT, with or without the Smarty, the ECM calls for 24.5k max pressure either way. I understand that the higher starting pressures might help to give the rail a "boost" when you go WOT, but that shouldn't have too much of an effect on longer runs (ie. 1/4 mile).
If you're saying the Smarty can dynamically add more increased pressure if/when the setpoints are not reached then I see what you're saying, but I'm not sure it works that way? I was under the impression it adds a certain amount across the board (which may ramp up progressively, but not really change dynamically).
I guess there's one way to tell for sure. Time to do some testing!
Let me use my truck as an example and maybe that will make my point a little more clear.
When I am running the mp8, I can adjust it so that my rail pressure is at 23k, 25k, or wherever I want it. If I turn the mp8 off with my other mods, I cannot keep that kind of rail pressure. The timing and duration of the Juice along with the larger injectors use up all the fuel in the rail and the pressure drops. By using electronics to call for extra fuel to be sent to the rail it is able to maintain a higher rail pressure.
So....
On your Smarty, by it calling for a certain rail pressure, it is actually calling for additional fuel above what would normally be supplied so that there is enough to keep the rail pressure up. It never allows the rail pressure to exceed factory specs, but it call for enough extra fuel to attempt to maintain good pressure. So you have to look at it as though the Smarty is calling for fuel ( to specifically increase rail pressure ) rather than pressure.
I'm not sure if that made any more sense or not, but I can tell you that even with my stage 1 cp3, without added pressure from the mp8 it the rail pressure will be low.
