These afr fuel controllers are a great addition.
The AFR+ and the EJK made by the same company.Easy to tune features that's on the fly. Set you afr value to were you want.It's that simple.
The AFR Plus or GEN 4 by Dobeck Performance brings together two technologies within one system to make it the most powerful, user-friendly tuning device on the market. AFR Plus combines an EFI controller with a wideband O2 sensor and AFR gauge to provide a user instant fuel trimming ability and feedback about their vehicle’s tuning operation. GEN 4 is the short term used to describe the Generation 4 Electronic Fuel Injection (EFI) controller and Air Fuel Ratio (AFR) Gauge Kit manufactured by Dobeck Performance. The GEN 4 is a piggy-back EFI controller because it does not replace the stock ECU, but rather monitors the signals to the injectors and makes fuel adjustments based on the mode settings. The GEN 4 has a push button interface on the gauge allowing access up to 6 different modes to allow for quick fine tuning by the end user without needing a computer.
AFR PLUS / GEN 4 FEATURES:
-FULLY COMPPATIBLE WITH ALL AFTERMARKET EFI CONTROLLERS INCLUDING REPLACEMENT ECUs.
-HAS CAPABILITY OF BEING YOUR ONLY FUEL MAPPING SOLUTION AS WELL IDEAL FOR MAXIMIZING FUEL ECONOMY FOR TRIKES, SIDECARS, PULLING TRAILERS, OR FIGHTING A HEAD WIND
AFR GAUGE FEATURES
-AFR GAUGE READING FROM 10 TO 16 TO PROVIDE INSTANT AFR FEEDBACK READINGS
-STANDARD 2-1/16" ROUND GAUGE WATER RESISTANT PUSH BUTTON INTERFACE TO ALLOW QUICK FINE TUNING AT YOUR FINGERTIPS
-EASY TO SEE LED LIGHTS TO INDICATE OPERATING ZONE ON THE GAUGE USES BOSCH WIDEBAND O2 SENSOR WITH BOSCH CHIP POWERED WIDEBAND CONTROLLER
-SELF-ADJUSTING BACK LIGHTING DISPLAY FOR NIGHT VIEWING
EFI CONTROLLER FEATURES
-USES LOAD BASED TECHNOLOGY WHICH ALLOWS FOR TUNING IN EVERY GEAR -
-3 MAIN ZONES OF OPERATION TO TARGET DESIRED AFR ABILITY TO ADD OR PULL FUEL WITHOUT ALTERING THE STOCK FUEL MAP
-CLOSED LOOP OPERATION OFF OF WIDEBAND O2 SENSOR INPUT
-PLUG N PLAY INSTALLATION - NO WIRE SPLICING
-NARROWBAND GENERATION FOR STOCK O2 SIGNAL
The Gen 4 Optimizer is the AFR+ Fuel Controller that combines an EFI controller with a wideband O2 sensor and AFR gauge to provide a user instant fuel trimming ability and feedback about their vehicle's state of tune. The AFR gauge allows you to know exactly how well your tune-up is performing at all times.
Understanding the modes on afr+
Mode 1 – GREEN – IDLE / LOW SPEED FUELING MODE – OPEN LOOP Represents fuel modification at idle for warmed up vehicles and at low speed conditions. When the LED display shows a solid GREEN light then the GREEN zone is active and fuel is modified by this mode.
Mode 2 – YELLOW – CRUISE FUELING MODE – CLOSED LOOP – ACTIVE MODE THE MAJORITY OF TIME Represents fuel modification for cruising speeds at low to medium load. When the LED display shows a solid YELLOW light then the YELLOW zone is active and fuel is modified by this mode. Has the largest affect on fuel mileage.
Mode 3 – RED – FULL THROTTLE / HIGH LOAD FUELING MODE – CLOSED LOOP Represents fuel modification under full throttle roll-on and high load conditions. When the LED display shows a solid RED light then the RED zone is active and fuel is modified by this mode. Has the largest affect on tuning for the vehicle’s top horsepower value.
Mode 4 – GREEN-BLUE – ACCELERATION FUELING MODE – OPEN LOOP Represents fuel modification under moderate to high rate of throttle openings.
Mode 5 – YELLOW-BLUE MODE – GREEN TO YELLOW SWITCH POINT Represents transition between GREEN and YELLOW zones. The YELLOW zone is load based and engages differently between gears and riding conditions. Move all the way to the right to enter DIAGNOSTIC MODE.
Mode 6 – RED-BLUE MODE – YELLOW TO RED SWITCH POINT Represents transition between YELLOW and RED zones. The RED zone is load based and engages differently between gears and riding conditions. Move all the way to the right to enter DIAGNOSTIC MODE.
Now if you don't want this gauge style,get the EJK and buy your own digital gauge(heath
)- NO COMPUTER NEEDED
This EFI controller is one of the only ones on the market which allows a large range of adjustability without the use of a computer. We like to use the term 'on-the-fly' tuning. You can literally drive the vehicle, make setting adjustments, and instantaneously feel the results. Obviously for safety purposes we recommend you pull over to the side before making adjustments. Some after-market EFI controllers like to claim 'on-the-fly' tuning which to them means toggling only between a couple preset maps. The controller actually has 11,390,625 available maps in the unit which are accessible without using a computer program to reprogram the unit. There does exist a computer program called POWERLAB and the controllers can be reprogrammed by a computer, but most users do not require this ability. Why deal with the complexity? It's an Electronic Jet Kit to make fuel injection tuning easy, simple, and fast so you can enjoy more time riding.
- NO DYNO REQUIRED
You do not have to be a professional mechanic or tuner and have access to a dynamometer in order to tune your vehicle with the EFI controller. Knowledge and good equipment obviously are a huge plus, but you can do just as good a job and sometimes better by tuning in real world riding situations. The controller allows this by breaking down a drive cycle into very understandable zones to make adjustments. Most controllers have the basic Idle/Cruise, Acceleration, and Full Throttle zones to adjust. Every rider can understand this terminology. The greatest advantage about tuning your vehicle yourself is your ride will be custom set up to your driving style.
- Plug N' Play Installation - Minutes to Install, Base Settings are Preset
All of the offered controllers are plug n' play installations and can be done in a manner of minutes instead of hours. All you have to do is locate the OEM injector connections on your vehicle. Most of the time this will only require you to remove a few components to gain access to these injector connections. A number of new applications will also require you to find the O2 connections on your vehicle if present. Power for the unit is gained through the injector connections and a black ground wire just needs to be attached to the negative terminal on the battery if present or by a metal screw onto the vehicle frame. After physically installing the controller in most cases you are all set to go on a test ride. The unit comes pre-programmed for a stage 1 setup for each application. After your initial test ride you then can make some fine tune adjustments which may be required based upon your modifications.
- Uses Unique Load Based Technology
The controller uses Load Based Technology which sets it apart from most of the competition. Most EFI controllers use what is called 'Alpha-N' Tuning Technology. Alpha-N tuning is associated with just using Throttle Position (TPS) and RPM as the factors to make tuning adjustments. Load Based Technology differs by using Rate, TPS and RPM as the key factors for adjustment. Load Based tuning allows a user to tune their vehicle for every gear and for all riding conditions. Load can easily be explained by stating that riding up a hill puts more "load" on the vehicle than driving on a flat road, but yet the same TPS and RPM can be achieved in both circumstances.
- Offers Full Range Tunability
The controller is sold as an Electronic Jet Kit. Like carburetor jet kits of the past the controller offers a range of adjustability to tune your vehicle. Instead of physical jets and needles the controller has this adjustability built into the unit and can quickly be adjusted while riding the vehicle. Essentially with all EFI vehicles software has replaced some hardware. The controller can be installed and set to actually allow the user to still run a stock configuration, but allows the user to ADD or PULL fuel within easy to understand tuning zones.
- Does Not Interfere with Stock ECU Operation
This is a very common feature of all after market EFI controllers, but needs to be stated to reassure all end users. The controller does not trip any engine codes or affect the ECU operation in any way.
- Simple Push Button Adjustment Interface
The controller offers 'on-the-fly' adjustment using three push buttons on the label interface. The three buttons are labeled MODE, PLUS, and MINUS. With power supplied to the box by either starting the vehicle or just turning the key on, the adjustment modes are accessed by pressing the MODE button. Light setting changes are then made for each respective mode by pressing the PLUS and MINUS buttons. No extra tools are required to make tuning adjustments.
- Water-Resistant
The hardware components within the controller are covered with a substance to make the controller water-resistant. The controller is still an electrical device and without this coating would short-circuit when in contact with water based substances. The controller is NOT 100% water proof, but will continue to function properly through rainstorms, snow, washing your vehicle, etc. Watch this YouTube video
