So does that mean you've installed and used it and are not impressed with it's capabilities?
Looks like throttle body injection. It says near the beginning it comes with either 4 or 8 injectors for 400 to 800 hp.
It's known as annular. Supposed to create better fuel distribution.
No but he knows what he's talking about. Dave you think this might be Arduino based LOL

All of this discussion begs the question how much better really is TBI than a carburetor? I still don't see enough of a difference to spend 1K on something to replace my beautiful running 100 buck carburetor. Not yet.
............ Some of the other aftermarket EFI's have injectors below the throttle blades (FAST, Edelbrock). ............. MSD makes a big deal about injecting through annular boosters above the throttle blades,.................. Holley injects below the throttle blades but makes a big deal about using annular rings similar to this one. Who knows which one is best? ..............
A TBI system if well tuned both with intake port balance and fuel controls may have some improvements over carb. The improvements would mainly be due to temperature compensations and O2 closed loop control. If TBI not properly tuned, a carb wins for simplicity, cost and the ability to drive around problems, using careful foot on the pedal control.
My observation of crude capability is not based on trying the system, but looking at the available tune settings via the programming interface. I compared those with features I developed, and have applied on many engines. There is a huge difference between getting an engine to run, and getting optimal performance for both power and economy. Settings need to be refined in a way to make adjustments based on more table points. Tuning tables need to follow engine dynamics of volumetric efficiency for fuel, and flame travel speed on ignition. The tables are surfaces with valleys, slopes and peaks.
To put this in perspective, the Fi system tunes ignition with a 3 x 3 matrix. I use a 16 x 10, this is RPM x MAP. Comparing 9 cells to 160, suggest a huge difference, modern OEM systems are more than double what I use.
I can go on about much more, but do not want to hijack the thread.
Frankly, at the cost of NEW carburetors, not something you found at a yard sale, this system seems pretty attractive to me. Only time will tell whether it holds up. There's been others.......some of which I never heard of until after they went bankrupt LOL
I don't see it as hijacking...it's parsing out the OP's question by addressing the advertised system's perceived lack of fine tuning resolution/capability to help him make an educated choice as to whether or not he might be interested in buying it.
Otherwise, what I gleaned out of this is that you believe if the OP wants to truly pursue EFI, he should go with an MPFI setup and buy a near infinitely tunable system like MS3 or similar...and that this system is no better than a well tuned carb and dizzy.
I hate to make it sound so...final, but if we don't speak in concise terms on here, it can come across sometimes as just talking around a question as opposed to actually answering it...I hope that makes sense.
One thing everyone is overlooking is the fact that you can plug a laptop into the handheld and pro tune this efi. The 3x3 matrix is for the guy who only wants basic tuning. I talking to the tech guy about this system for about an hour and he could've kept going but it was getting over my head. He was said a Mpfi is coming in a couple months.
I've had $100 carbs all my life and a few that ran really well. But I have yet to find any carb that runs better than even the basic tbi. I know what you're saying Rusty, but if it works as well as they say, they'll have my $1000 before the end of the year. I've been looking at it pretty hard all day since I saw the post. All I want is basic efi that can self adjust to cold, hot, and yes I like the quick fuel, msd, and fast the best but for the life of me I can't understand why it cost so much. It's just thottles bodyI still don't see enough of a difference to spend 1K on something to replace my beautiful running 100 buck carburetor. Not yet
