● INTRODUCTION
Nowadays, engines of motorcycles and cars are equipped Programmed Fuel Injection technology (PGM-FI), it replaced for previous mechanical control systems.
This system provide many advantages compared to previous generation of engine performance, fuel consumption optimize, smart, convenient, safe for users and exhaust pollution decrease, environment protection.
Beside above advantages, there are still many defects, which in fact have not been resolved as below:
- PGM-FI system only works perfectly when it is very new, after short time (about one year) engine technical parameters has not reached standard. Example: engine fuel consumption is more than old carburetor system and it creates more pollution emissions.
- The cost for repair and replacement is more expensive after a few years of operation.
- Especially, Electronic control technique in motorcycle/ car repair is complex. It requires repairer must have high technical qualifications. Besides, electronic control modules (ECU) has integrated designed and do not allow adjust parameters due to deviation of components in ECU.
- Some designs and software programming inside ECUs still have many errors that have not fixed and it created many difficulties for technician.
AFO-3S model supports anti-theft function by secret code without using "magnetic card", consuming power form batery. The vehicle can only start engine when the owner enter the security code by holding/releasing brake and opening/closing throttle.
AFO-3 – The abbreviation of an electronic accessory will be adding on the new generation motorcycle and car that used Programmed Fuel Injection technology (PGM-FI). It allow user adjust optimally fuel injection system to standard value of engine. AFO-3 is researched and manufactured by DTDAuto Technology Team, Institute of Physics, Vietnam Academy of Science and Technology. With AFO-3 all above troubles will be solving intelligently, automatically or can be adjust optimally by technicians to makes vehicle run better and less environment pollution.
● FEATURES
- The device is designed with intelligent microcontroller technology, it like as a secondary ECU that optimize A/F ratio according to the actual load status of engine
- Only optimize A/F ratio to repair slum power when accelerate without changing fuel injection quantity at the other loading conditions, so do not rich fuel when operating in the normal load mode.
- Can adjust A/F ratio depending on user's demand
- Keep the original wiring harness, no need to cut wiring during installation
- Quick installation time and simple operation with dedicated wire clamp
- Update, upgrading the next software versions via internet
- Equipment is stable, watertight and low energy consumption
- Especially: AFO-3S supports the anti-theft function for motorbike (if vehicle is starting, user turns off the engine but no more than 10 minutes then turn on the ignition key or vehicle shutdown due to Idling Stop mode, AFO-3S will recognize that this is still the owner and no require entering security code)
- Equipment can be installed for all types of FI motorcycles and cars using electronic fuel injection system with AFO-3 1, 2, 4 and 6 channels

● FUNCTION
1. AUTO REPAIR SLUMP POWER FAULT WHEN ACCELERATE FOR PGM-FI HONDA
2. CALIBRATE A/F RATIO FOR PGM-FI MOTORBIKE/ SCOOTER
Proactively calibrate Air/Fuel ratio to recover faults related to fuel rich/lean caused by ECM fault as more fuel consumption, weak engine, Idling Stop …. that need not replace a new ECM
3. CHANGE FUEL CONSUMPTION AND ENGINE POWER OF PGM-FI VEHICLE IN CASE OF YOU HAVE SPECIAL DEMANDS
- Proactively adjust the less fuel consumption in case of users are old people that only need fuel economy consumption and needn’t quick response engine power.
- Proactively adjust rich fuel than normal design of vehicle in case of user is young people that want quick acceleration engine, “strong engine”.
4. ANTI-THEFT SYSTEM
Only the owner of the vehicle knows security code can start engine. This is the extra function of AFO-3S kit.

-
Step 1: Turn off ignition key
-
Step 2: Remove out the seat, storage box then connect exactly circuit as below image:
2. NOTES IN AFO INSTALLATION FOR PGM-FI HONDA
Connector of HONDA injectors have 02 types are common and special connector (reverse connector), about 90% are common type, only 10% are reverse type. To determine type for connector, you must plug-in AFO connector to vehicle connector same as the image below. Look at wiring color type:
- If wire color of connector are same side then that is common connector type.
This case, don’t need to change anything in the installation
- If wire color of connector are reverse then that is special connector type (reverse connector). Look at the image below:
This case, you must invert wires of injector connector on motorbike firstly
