The Commander440 ECU is the new version replacing the Commander44 ECU (which is no more manufactured). It owns a twice as much memory size which allows supplementary calculations, larger maps, and an improved security of the CAN-Bus transmissions.

The Commander440 has been designed for those who want an exceptional ECU. It allows managing 1 to 4-cylinder engines in sequential injection and static ignition, and 6 and 8-cylinder engines in semi-sequential injection and lost sparks ignition.

Thanks to its high performance microprocessor and its multiple possibilities the Commander440 allows to get astonishing accelerations by a total engine optimization.

Several tunings can get along for the same engine (multimapping). The desired tuning can be selected while running, by a rotator or a dashboard switch, allowing the adaptation to the driving conditions, a super boost of the engine if necessary.

A full self-learning function allows the ECU to auto tune its injection time map when equipped with a wide band Lambda sensor (needs a professionnal license, or on option with standard license).

• 4 injection channels (sequential injection, semi sequential or direct inductive and direct piezo)
• 4 ignition channels (static ignition or lost spark)
• 10 fully programmable auxiliary outputs (including motorized throttle management, proportional camshafts drift, FISA regulation fuel pump, ...)
• RPM sensor selectable Hall effect or inductive on crankshaft flywheel
• Main phase sensor selectable Hall effect or inductive on camshaft flywheel
• Auxiliary phase sensor selectable Hall effect or inductive on camshaft flywheel
• 1 internal power supply tension measurement
• 12 resistive inputs NTC-PTC-PT200 or logical (of which 8 by CAN-BUS connection)
• 17 analog 0-5 volts inputs (of which 8 by CAN-BUS connection)
• 1 selectionnable analog-resistive input
• 1 differential 0-5 volts input
• 8 speed inputs fully programmable (of which 4 by CAN-BUS connection), Hall effect or inductive selectable, number of teeth from 1 to 128

For a fast tuning, the maps of engine start, engine temperature rise, accelerating pumps and atmospheric altimetric pressure and intake t° corrections are preset for the ignition advance as for the injection.
The PID of devices commands (electric throttle, air intake proportional electrovalve, turbo) are also preset.

Very advanced engine management functions allow a total optimization of the engine working:
• Cylinder by cylinder correction of injection and ignition
• Operation in two injection rails with gradual shifting from one to the other
• Proportional positioning of camshafts
• Fuel pressure management
• Injection correction by fuel pressure
• Correction of richness by wideband Lambda sensor
• Management of the electric throttles (with specific tuning allowed by gear position)
• Direct injection engine management (see direct injection kits)
• Multi fuels and additive management

• Rpm limiter on injection or ignition
• Cylinder per cylinder cutoff with rotation of the first cylinder cutoff (engine protection)
• Modifiable rpm limiters following gear position, intake temperature or engine temperature or elapsed time in limiter
• Several launch limiter and race limiters, selectable by a rotator (rotary switch) at the vehicle board
• The different launch limiters allow to adapt to the road grip conditions
• Tunable gradual limiter raising from launch limiter to race limiter to avoid wheels slipping at vehicle take-off

Sequential gearbox management or specific management of robotized gearbox.
• Logical or analog switch (strain gauge) with definition of the triggering thresholds
• The order of gears can be automotive type, motorcycle or special
• Intervention time in function of gear position, rpm and engine torque
• Intervention at gear upshift on ignition by cutoff and/or advance modification with slope of return to normal (transmissions protection generating bang and exhaust flame)
• Engine automatic acceleration (autoblip) at downshift

The proportional positioning can be made on one or two camshafts.
• intake camshaft
• exhaust camshaft
The proportional positioning is executed by a PWM command for each electrovalve of camshaft, with selectable frequency.
The camshafts targets can be:
• on state mark
• on position mark
• on one missing tooth
• on regular teeth (exhaust only)

• Turbo management in pressure or in turbo rpm or both with dynamic choice of the type of management
• Turbo protection by turbo rpm limitation
• Management of wastegates with back pressure
• Pressure and turbo rpm target tunable according to gear position, exhaust or intake or engine temperature, altimetric pressure
• Bang-bang (antilag system) at the starting up for cannonball launch
• Bang-bang managed with fly by wire, proportionnal air electrovalve or mecanical throttle opening device
• Bang-bang monitoring by exhaust temperature
• Bang-bang disabling by dashboard switch for road driving
• Programmable injection of water

See Direct injection inductive kit and Direct injection piezo kit.

• Programmable reaction (by limitation of torque, rpm, or engine cutoff) on problem of oil pressure, engine temperature, turbo pressure, with alarm lights and recording of the defects

• Every measure has a customizable digital filtering
• Every measure maybe assigned by calibration to a physical input of the ECU, to a calculated value (ie double potentiometers), or to a CAN-BUS sensor
• For every measure of the ECU, it is possible to define a strategy of detection of defect, a strategy of replacement value in case of defect, or to use the standard strategies supplied by the ECU
• Turbo speed, wheels speed
• Wideband Lambda sensor
• Oil pressure, fuel pressure, oil t°
• Exhaust temperature by thermocouple module or PT200

Extremely flexible and simply programmable strategies allow the motorist to multiply the possibilities of tuning
The use of these advanced functions and the development of specific strategies does not require either the learning or the knowledge of a programming language. The innovative and natural technique, called SKYMCOD Mapped programming, developed by Skynam, performs this role.
For example,
• Several selectable possible engine tuning by rotator or by quite other condition chosen by the motorist (for example multi fuels with programmable switching, additives)
• Addition of engine devices (intake flaps, exhaust throttle)
• Programmable auxiliary inputs for new measurements creation
• Management of restrictor pressure for overboost engines
• Programmable injection of water
• Limitation of acceleration or vehicle speed
• The ECU can react to the oil temperature or to the oil pressure according to the rpm or to quite other parameter or the combination wished to control, activating alarms or switching off the engine, or changing the strategies of injection, ignition, overboost, command of the electric throttle, or other
• The motorist can intercept all the targets of the Commander (injection, ignition, turbo pressure, bang-bang, fuel high pressure, proportional positioning of camshaft, richness correction, rpm limiter, motorized throttle) and modify them with his appropriate strategies

A completely programmable auxiliary CAN-BUS (11 and 29 bit identifiers, speed until 1 Mbits) allows to exchange data with the others connected nodes, car manufacturer devices or data recording or dashboard. The received data can be used in the advanced functions of calculations and developments of strategies.

10 completely programmable auxiliary outputs.
They can be configured in On-Off (programmable hysteresis), PWM from 10 to 10000 Hz or angular or engine synchronous phased commands, with adjustable cyclical ratio (and phase), and piloted by any combination of parameters known by the ECU, including the values received from the auxiliary CAN-BUS, andor from the sophisticated strategies developed by the motorist and fully configurable PIDs.

• The kit is made of the Commander440 ECU supplemented with accessories to install it on the engine. The kit we provide is specifically designed for 4-cylinder engines with full monostatic ignition and sequential injection.
If your engine has a higher number of cylinders, you maybe need to purchase some complementary accessories.
In any case, report to kit complements below to verify your needs

• The CAN-BUS connection-to-PC kit is not included in the ECU kit. It is to be ordered in option or to be purchased separately. It is essential to be able to connect your PC to the Commander ECUs and tune the engine.
