Anyone have experience with it?

Yup as aux fuel for DI vehicles. Work good when hooked up properly. It does bank/batch fire tho and not sequential or atleast the boxes my friend at the shop used

Thanks!
They have 2 different versions that each run 4 injectors, ( I was thinking of adding 4 injectors to a plenum ) one uses absolute pressure, so I asked them about splicing it into the stock MAP, no reply yet, the other uses gauge pressure.
4 of the EBay 80-pounders at 85% DC should add enough fuel for at least another 500 HP safely.
And the whole deal costs less than one dyno-tune.
I also asked them if it's compatible with the wideband I already have, and if it can automatically adjust to 12.5:1.
I should have their response today.

I am not sure what you are building but the controller just controls injectors with the ignition system. It pulses with the ignition via tach signal. Its not a smart efi ecm to tune with via wideband. It should be programmable for cycle duty my guess to control amount but i dont think it auto tunes

And i hope you arent trying to use this as a way to bypass a proper tune job to the primary pcm/ecm and injector system. You only need additional injectors in situations where you cant get enough fuel via 1 set of injectors while getting proper idle and low speed fuel control. ie small cube motor like 4.8l with 2000 cc injectors. That will not idle well, too much fuel

Ok, I am trying to do a turbo 4.8L LSx without paying $400 to a chassis-dyno shop. I have 3 intake manifolds, so I can screw up 2 of them trying to add cheap injectors. Meaning a total of 12 injectors on this V8; 8 stock ones, plus 4 huge ones.
If this AIC ends up costing me $400, well, at least I own the means to keep trying over and over, like unlimited dyno pulls. That's worth it. Tools are always worth buying. Buying a dyno pull is like paying for an oil change.
I don't know much about their software yet, but I do have a laptop that'll work.
This thing shouldn't be adding any fuel when there's no boost, and that means no rich idle problem.
Plus if I succeed, then I can sell screenshots of my laptop to anyone else wanting cheap power enough to copy my parts list.
This isn't what I originally hoped for, but whatever works cheaply enough. I can still have good MPG, good driveability, clean emissions, and huge power reliably, at a fair price anyone can afford. And that's all that matters.

Plus the sad part is that Split Second gets all the profit from my hard work. That really sucks.

I just dont follow the logic here. You need to tune the thing regardless of what method you use to bring fuel in. Whether its the stock style lsx intake with 8 total injectors, or you run additional 4 in the plenum.
Either method needs tuned.

So your choices basically are do it yourself using hptuners for lsx pcm and buying large enough injectors for your setup
Or
You run a stock 4.8 tune with stock 4.8 injectors so you dont have to touch the fuel tables for the turbo setup, and tune the AIC driver for the additional fuel in boost

You arent bypassing a tune in either case and option 2 does not allow you to tune timing which IS needed for this turbo stuff to work and live.

And to behonest your best bet is to street tune the car as most chassis dynos arent gonna load the motor hard enough. The tune you get from the dyno guy will be useless for the street and track unless you use someone who knows the difference and who will dial in the setup with you on the street after a dyno baseline. And thats why it costs as much as it does

You really are ignorant aren't you? I can wait to see how many engines you chernobyl because you were too cheap/stupid to just pay for a tune. Stop making stupid threads, Do you really think it will live under boost with the factory timing table. Never mind the multitudes of other issues you will run into. Stop being cheap. your threads are annoying, or do we need to get a bunch of people to make you go away again like you "canned" boosted LS tunes.

Here you had a second chance to help, and once again you turn into a donkey and bash. eff you.

Help? here's some help. stop trying to re-invent the f***ing wheel and pay to have a dyno tune done, or buy HP tuners and learn to do it yourself. until then shut the hell up with the stupid ideas. Or atleast post pictures of the carnarge after you melt the engine in half.

Bypassing the most important part of an EFI car is a fool's errand. If you can't afford to tune it, skip something else. The tune isn't something to skip out on, especially when boosted.
Instead of making any other tune bypass threads, research how to tune the car.
