ECU Functions

Engine Configuration
- 20,000 rpm capability
- Flexible and easily adapted to different OEM, crank, cam sensor arrangements
- Genuine four and two stroke support
- Twin spark engines
- Twin injector engines
- Sequential or grouped injection
- Individual coils, wasted spark or distributor
- Unequal coil firing capability
- Unequal injection angle capability
- Delayed sequential injection
- User controlled fan activation
- Sensors can be calibrated individually with a lot of preset options supplied
- Flexible Tacho Output
- Soft and hard rev limits

Main Fuel and Ignition Functions
- Two main fuel, spark and turbo maps selected by a dashboard switch
- Comprehensive start up fuelling options both time and temperature dependant
- Air, coolant and manifold pressure compensation maps
- Throttle transient increase compensation
- Throttle transient reduction compensation
- RPM and load breakpoints can be calibrated by the user
- Throttle or MAP as load
- All maps with one or two dimensional with interpolation as required

Lambda control functions
- Extensive lambda parameters table to ensure stable closed loop operation and emissions requirements can be met where needed
- Full three dimensional lambda target map
- Auto-tuning function

Turbo Control Functions
- Open or closed loop turbo pressure control via PWM valve
- Modify target turbo pressure by gear selected
- Modify target turbo pressure by vehicle speed
- Two control maps selected by switch on dashboard
- Active base PWM map for easy calibration

Idle Control Functions
- Open or closed loop idle speed control via PWM valve
- Closed loop idle target speed temperature dependant
- Active base PWM map for easy calibration
- Fuel enrichment table calibrated versus PWM percentage

ALS Control Functions
- Full ALS ignition and fuel maps
- ALS valve control together with map switching controlled by dash board switch

Cam Control Functions
- Open or closed cam advance control via PWM valve
- Static offset table to zero out electrical movement effects
- Active Cam Target Advance map, load and speed dependant

Water Injection
When not being used to control the camshaft, cam base PWM map can be used instead for water injection, giving complete load and speed dependance.

Flexible Input/Output
Three uncommitted input tables which use 0 5 volt inputs or any input the S60 knows already, linked to fuel and advance modifiers and a PWM output.

Launch Control
- Fully flexible first gear launch capability
- Extensively tunable to individual vehicles

Full Throttle Gear Shift Cut
Shift cut capability with 1ms resolution, variable for each gear with full switch de-bounce capability.
 

Voltage Compensation Tables
User configurable voltage compensation tables for injector dead time and coil on time (dwell time).

Firmware
The ECU firmware is flash upgradeable via the serial port with a special calbe and software. Current firmware and software published on www.alons-autosport.nl.

CAN PC Communications
The ECU can communicate with the PC via our USB -> CAN converter. This solves the problem of unreliable USB -> RS232 converters.

Data Logging
- Up the thirty six seperate items can be logged
- Three user selectable logging frequencies
- Up to 9 hours logging capability
- Graphing can be done on-line to the ECU

Diagnostics and Test Features
- Full sensor diagnostics and fault recording
- Extensive engine run time recording at different load and speed conditions
- Ability to exercise injectors and coils without engine running for fault finding
