SUPER AFR

The HKS Super AFR is the very first airflow meter correctional device in the industry with a built in CPU. The advantage of having a built in CPU is that instead of making corrections to the airflow meter voltage, the characteristics of each airflow meter is inputted in the CPU so it can calculate the accurate amount of air flowing in. Since the correction will be made to this specific intake volume, the correction ratio of fuel will be precise and proportionally correct. The Super AFR is compatible with most Import and Domestic 12V, 2~12cylinder vehicles that utilize a hot wire, Karmen Vortex, or pressure sensor. The internal CPU allows it to be versatile and be utilized on many of the newer type airflow meters. Also incorporated in the Super AFR is the ability of idle air/fuel ratio corrections as modification progress and require further specific tuning levels. The response function, similar to the one in the VPC, allows for adjustments to the fuel settings upon throttle inputs to improve driveability and performance. The EIDS function is automatically programmed with the data from the initial self-learning calibration and automatically activated to correct sudden imbalances is air/ratios from discharge valves upon deceleration.

NOTICE

This manual assumes that you have and know how to use the tools and equipment necessary to safely perform service operations on your vehicle. This manual assumes that you are familiar with typical automotive systems and basic service and repair procedures. Do not attempt to carry out the operations shown in this manual unless these assumptions are correct. Always have access to a factory repair manual. To avoid injury, follow the safety precautions contained in the factory repair manual.

BULLET CONNECTOR INSTALLATION

1. Remove a small section of insulation at the end of the wire to expose the wire strands.
2. Determine which connector (male/female) is needed.
3. Install the appropriate clear cover over the wire.
4. Crimp the center section of the connector onto the exposed wire strands.
5. Crimp the rear section of the connector onto the insulated portion of the wire.
6. Pull on the wire and the connector to confirm a good connection.

SPLICE CONNECTOR INSTALLATION

1. Place the wire to be spliced into side A (the side without the stopper) and the wire from the AFR to side A (the side with the stopper). Make sure the wire touches the stopper.
2. Fold side B over side A using pliers, making sure the snap
is secured.
3. Fold side C over and make sure it snaps completely closed.

NOTE: Do not strip wire ends. Gently pull on the wire to insure a proper splice.

SUPER AFR INSTALLATION

1. Disconnect the negative terminal from the battery.
2. Locate the factory ECU using the factory shop manual and the SUPER AFR wiring chart portion of this manual. If the vehicle is equipped with an HKS FCD, install the SUPER AFR between the FCD and the factory ECU.
3. Use the supplied SUPER AFR vehicle specific wiring diagram and the factory repair manual as a reference to confirm the locations of :
· B- 12 volt ignition
· U- 12 volt battery
· E- Ground
· P- Pressure sensor, air flow signal
(Note: some applications have multiple "P" signals-Use P(AFR) for AFR and P(FCD) for FCD)
· I- RPM signal
· S- Speed Sensor
· T- Throttle Position Sensor
· #- Injector Signal

4. Connect the Super AFR with the supplied connectors to the appropriate wires as shown in the diagram.
· Connect the red wire to (B) the 12-volt ignition power source.
· Connect the black wire to (E) the ground source.
· Cut Pressure sensor / Air flow signal wire (P);
-Connect the yellow Super AFR wire to the portion of wire (P) going to the factory ECU (AFS Output).
-Connect the white Super AFR wire to the portion of wire (P) going away from the ECU (AFS Input).
· Connect the brown wire to (I) the RPM signal. [Must be a used with a 5V digital signal - For applications with an analog signal, a HKS REV-ad - signal adapter (PN # 4599-SA002) must be used.]
· Connect the orange wire to (T) the throttle position signal.
5. Re-examine all wire connections for proper installation.
6. Securely mount the Super AFR using double sided tape.
7. Reconnect the negative terminal to the battery.

SUPER AFR SET UP

1. Air Meter Type Selection
The DIP switches allow for the selection between Hot Wire, Karmen Vortex, and Pressure sensor calibrations for the Super AFR. The airflow meter type settings are made with the combinations of DIP switches 1 and 2 as listed below.

2. Voltage Switch Setting
This switch is specifically used to select between the normal Hot Wire voltage range and the specific 1999+ Mazda Miata (NB8C) voltage range. When using the Super AFR on a Mazda Miata, the voltage switch should be in the left position as pictured below. For all other applications, the voltage switch should be in the right position.

3. Option Output Settings
The Super AFR can be used with F-CON MINI and AIC MINI.
Connect the blue wire of the Super AFR and switch the Super AFR DIP switch 3 to the ON position as pictured below.

4. Cylinder Number Selection
Turn the key to the ignition (12 V) position. The numeral "2" should be flashing at this point, indicating that the Super AFR is set at "2" cylinders. Select the number of cylinders by turning the Response Knob on the front of the Super AFR.

* Cylinder settings can be made from between 2 ~ 12 cylinders. *

* NOTE: If the wrong number of cylinders is inputted, the rpm signal will not match the actual reading *

5. Self-Learning Calibration
The Self-Learning mode will automatically calibrate the Super AFR to the vehicle's Airflow Signal and Throttle Position Signal voltage. To activate the Self-Learning mode, make sure all accessories are turned off (A/C, lights, stereo, etc.) and then start the engine. The display will now show the engine rpm. At this point, set the Idle to "0" and turn the Response knob to "0". Let the engine warm up to normal operating temperature (Level where water temp is stable). While the motor is at full operating temperature, switch DIPswitch 4 to the ON position as pictured below. Self-Learning mode is now complete.

* NOTE: If the engine shuts off at anytime during the learning mode, you must start over from step #1 *

SUPER AFR TUNING

HKS RECOMMENDS TUNING FOR THIS DEVICE TO BE DONE ON A CHASSIS DYNAMOMTER ALONG WITH THE USE OF AN ACCURATE AIR/FUEL RATIO MEASURING DEVICE.

TUNING ATTRIBUTES AND RANGES
· Airflow Meter / Pressure Sensor Correction Function
- Idle Mixture
Idle mixture can be adjusted in the range between 650 to 1500 rpm.
Adjustments are independent of the eleven Gain mixture settings
Settings can be adjusted between -50% ~ +50% in 1% increments.
- Gain-Fuel Curve
Airflow output corrections can be adjusted in the range between 650~8000rpm.
Eleven adjustable settings between 650~800rpm that can be arbitrarily adjusted in 50rpm increments.
Settings can be adjusted between -50% ~ +50% in 1% increments.

· Response function
The engine's initial throttle response can be adjusted to improve driveability and over all performance.
6 adjustable RPM point settings between 650~5000 rpm that can be arbitrarily adjusted in 50rpm increments.
RPM point setting values can be made between the range of 1m/sec.~100m/sec. in increments of 1m/sec.

· EIDS function
The EIDS correction function, an electronic idle stabilizer, is automatically enabled after performing the Self-Learning calibration. The EIDS will automatically compensate for sudden imbalances in air/fuel ratios at idle and at deceleration.

MONITOR MODE
In Monitor Mode, the Super AFR will display the current engine rpm and fuel % change values. The rpm function displays the current rpm in 1/10 of the actual rpm. The fuel % value function will display the current % gain change according to the current engine speed. Press the Gain knob to toggle between the rpm display screen and the % gain display screen. The EIDS indicator will light up during its automatic operation when the airflow signal surpasses the set range of inputs when the throttle is released. The response indicator, Rsp, operates in the same manner in regards to the response function.

IDLE FUEL % SETTING
While in Monitor Mode, depress the Idle button so that it pops up. Rotate the knob to adjust the idle fuel mixture % between the range of -50% to +50% in 1% increments over the factory setting- Clockwise to richen and Counter-Clockwise to lean out. As you adjust the knob, the numeric setting and the % indicator will blink. After you have selected the numeric % value, the number and % indicator will stop flashing and will revert back to monitor mode to indicate that the setting has been saved into the memory and the idle setup is now complete.

GAIN ADJUSTMENT MODE
Adjustments to the fuel curve on the 11 RPM points between 650rpm ~ 8000rpm (arbitrarily adjustable in increments of 50rpm) can be selected for fuel % adjustments from -50% ~ +50% in increments of 1%.
