I have 2 ecu's
1st HKS F-Con V-Pro V3.2 (uk tunable) with Full 4 plug harness 93-96 classics, Air temp sensor and housing (replaces MAF) and MAP sensor
Here is rundown comparison against the other top market contender. (not written by me)
HKS F-Con V Pro
&
Apexi Power FC
The necessity for optimum control over a vehicle's engine is heightened as
a car's engine is modified and transformed beyond intentions and parameters set by manufacturers
and controlled by the stock Engine Control Unit. At clubman levels, where the investments into engine
modification and aftermarket upgraded engine components are high, the particular need for
precise control is paramount into both longetivity of the engine, and ability for the user to
gain full advantage of the investment he/she has made.
The requirements of an aftermarket ECU are that it must enable the user to adjust and alter the fuelling of the engine,
the ignition timing of the engine, control over auxiliary engine functions, to record and monitor the engine's activity,
to enable interaction between the user and the ECU, and incorporate safety systems and fail safes to ensure against
engine damage.
The following is a comparative analysis of each of the aftermarket ECUs I have chosen to study.
ECM Type
(A description)
HKS F-Con V Pro:
A fully featured stand alone engine management system incorporating a "piggy-back" fuel computer interface.
- Utilises Factory ECU
Apexi Power FC:
A complete stand alone total engine management system
- Replaces Factory ECU
Resolution of Adjustability
(What levels can user adjust main fuel/ignition points to)
HKS F-Con V Pro:
32x32 Fuelling & Ignition Point Adjustment
User defined selection range
Apexi Power FC:
20x20 Fuelling & Ignition Point Adjustment
5x5 map sections
Ability to control drive by wire?
HKS F-Con V Pro : Yes
Apexi Power FC: No
Engine Monitoring System
(What can the ECM monitor?)
HKS F-Con V Pro.
- Complete total engine monitoring via software
- Parameter Limts / Warning Functions user defined for any variable.
- Datalogging Function enables user to record and re-run data accumulated through all of car's sensors over defined period of time.
Apexi Power FC.
- 10 monitored parameters displayed via commander
- Engine RPM
- Ignition Timing
- Vehicle Speed
- Air Flow Voltage (Pressure Sensor Voltage)
- Injector Duty Cycle
- Boost
- Knocking Level
- Battery Voltage
- Intake Air Temp
- Water Temp
Functions
HKS F-Con V Pro.
- Total Control over Car's Electronic Systems.
- Main Functions include:
- Ability to store 4 different fuel/ignition/boost maps
- Fuelling Mapping
- Ignition Mapping
- Boost Mapping
- Injection Format
- Additional Injector Control
- Nitrous Oxide Injection Control
- Launch Control
- Multiple User Defined Rev Limits
- User defined activation levels via pressure, speed, revs, temperature
- Acceleration Enrichment Correction
- Cranking Fuel Injection Control
- Water temp / fuel injection control
- Anti-Lag Control
- Leading & Trailing Ignition Control
- Water Injection Control
- Boost Ramp Control
- Auto A/F Ratio Compensator
Apexi Power FC
- Fuelling Mapping
- Ignition Mapping
- Boost Mapping (with seperate boost control unit)
- user Defined Rev Limit
- Acceleration Enrichment Correction
- Cranking Fuel Injection Control
- Water temp / fuel injection control
- VTEC Control (on Honda Vehicles only)

Injection Format?
(How can the ECM Control different injection formats?)
HKS F-Con V Pro.
- Batch, Sequential or Staged
Apexi Power FC
- Sequential Only.
Datalogging Function?
HKS F-Con V Pro.
- Yes
Apexi Power FC.
- No
User Interface
(How does the user access the ECM?)
HKS F-Con V Pro:
Through Software
Apexi Power FC:
Through Commander
Safety?
(How does ECM ensure engine safety and longetivity)
HKS F-Con V Pro
- Auto A/F Ratio Compensator
F-Con will calibrate entire engine mapping to suit user defined correct A/f Ratio, and will never let
engine run detrimentally lean (e.g in a case of a blocked injector)
- Warning Levels pre defined by user
- Limp Mode Activation pre defined by user
- Cut Off Activation of any ECU controlled electrical system, defined by user
- Use of aftermarket sensors to ensure more accurate readings.
- Datalogging.
- Active Parameter Display, Warning, Peak and Hold and Recording via software
Apexi Power FC
- Peak and Hold Function via Commander
- Warning Level Activation via C.E.L
