RSR AIC400 Additional Injector Controller
Don't rip out the factory stuff
The RSR AIC400 is the answer to fuel control on fuel injected vehicles that employ turbochargers or superchargers. There is no need to rip out the factory fuel injection or emission equipment and there is no need to "reprogram" the stock computer. The OEM i.e. the factory that designed the power train has spent millions of dollars and thousands of man-hours to get your vehicle to run perfectly as possible under every imaginable condition...why in the hell would you try and outsmart them. Trying to reprogram your stock computer is a huge waste of time and money with no guarantees of success in spite of what others will tell you. A practical consideration is the need to have full OEM emission gear in place for smog checks...with the AIC400 you don't have to reprogram anything or go digging around in your garage for all the emission crap you ripped off in your quest for power.
RSR AIC400: Custom Programmed for your application
RB Racing's RSR AIC400 simply augments your factory fuel injection by adding 1 to 4 fuel injectors to meet your engine's turbo/supercharged needs. The AIC400 is custom programmed for your application based on six parameters: (1) Your maximum vehicle rpm; (2) Your stock peak horsepower (you can supply a Dyno Chart); (3) Your expected peak turbo/supercharged horsepower; (4) Your vehicle's fuel pressure (Note: no rising rate fuel regulators ala Cartech etc.!); (5) the number and size (use injector calculator and injector list below) of additional injectors you wish to run (1 to 4). (6) Whether you need a 0 to 10 psi, a 0 to 15 psi, or 0 to 30 psi system. When you order your AIC400 simply add comments answering these six questions. For you to play around with the numbers we have created an Excel spreadsheet AicWeb.xls that you can 
download. Fill out and email back to us the completed spreadsheet and we will custom program and ship you the RSR AIC400 set to your specifications.
Technical Issues
Fuel pressure has to track manifold pressure in a forced induction system, i.e. fuel pressure has to remain constant relative to manifold presure. In vacuum the pressure will be lower and as boost rises it will rise with the boost pressure on a one to one basis. If your fuel injection system does not reference manifold pressure you are going to have to change your fuel regulator. If you do not change the fuel regulator as the boost rises you will get less and less fuel delivery. Do not use the incredibly stupid large diameter rising rate regulators that a favored by the technically impaired. These large diaphragm regulators exponentially increase your fuel pressure as the boost rises virtually insuring your fuel curve will be absolutely incorrect everywhere except one tiny little point...anything above or below this pressure ratio will be absoluely wrong. Fuel injection has enough variables to deal with and the correct method is to keep fuel pressure constant relative to manifold pressure. We have seen more blown engines from incorrect fuel pressure and stupid enginnering than we care to mention. Just remember, when that injector "opens", it "sees" the manifold pressure.
AIC Futures, pork bellies and selling short
Hey, things change...nothing is constant these days except change. The AIC400 won't be caught by market downturns, component upgrades, vehicle changes or, heaven forbid, bad decisions born by the marriage of Over-estimation to that scoundrel SWAG (scientific wild ass guess). Because your AIC400 has quick detach waterproof connectors you can go from one to four injectors simply by plugging on a new harness. The same goes for the M.A.P. sensor...unplug a two bar sensor and plug in a three bar sensor. AIC400 programming is contained in a plug-in computer chip that can be upgraded at anytime. If you put on a bigger turbo, change engines, bump the displacement or even change vehicles, the AIC400 can adapt. Evolution won't catch your AIC400 on a branch to nowhere or, as they say in the real world, a dust filled oblivion in the land of garage shelves. You won't find an AIC400 whimpering for a second chance at a swap meet.
Four fuel maps and a trim knob
The RSR AIC400 has four user selectable fuel maps and a +/- 10% Trim Knob...all of which can be switched or adjusted while the vehicle is running. RB Racing will custom program your AIC for your vehicle's specific requirements and with the switchable maps and the Trim Knob you will be able to go ten percent above or below these levels in a vernier fashion. Simply use the RSR Air/Fuel Ratio Gauge to quickly set your vehicle for a perfect maximum power mixture.

Ready to go, not ready to blow
The key to the success of the RSR AIC400 is that it is a digital microprocessor based system that does not rely on a series of analog based potentiometers or slides to "guestimate" you fuel needs. By the time you figure out one of these glow in the dark wonders you will probably damage your motor, or simply go bonkers over the five to seven adjustments they present you. How people expect you to accurately set these with any form of "repeatability" is beyond us!
Your RSR AIC400 is shipped to you with an absolutely correct fuel curve based on the five inputs. It will be shipped with the switches set to the middle of the range, exactly to your specific hp requirements. In order to evaluate your fuel needs we suggest you purchase one of our RSR Billet Air/Fuel Ratio Gauges, without which it is impossible to evaluate engine conditions in "real-time".
2 models: 15 psi, 30 psi
RSR AIC400s are available in two models: (1) 2 BAR [0 to 15 psi] Turbo/Supercharged; and (2) 3 BAR [0 to 30 psi]. In addition to the AIC you will need to order a wiring harness for 1 to 4 injectors and either a 2 BAR or 3 BAR map sensor. If you need to order injectors we can supply the 1 to 4 high impedance or the one (1) low impedance injector required.
Supports 1 (2-3 Ohm) to 4 (12-16 Ohm) RC Racing Injectors (shown @ 43.5/55 psi)
RB Racing stocks the full range of RC Fuel Injectors, both high (12-16 Ohm) and low impedance (2-3 Ohm) styles.
High Impedance RC Racing Injectors are available in the below listed sizes, all rated at the industry standard of 3 BAR (43.5 psi). In as much as RSR Fuel Injection Systems typically run at 55psi, we have supplied both figures for each injector.
