The Commander66 was designed for those who truly seek the Win. Its speed and its computing power allow astonishing accelerations. From 1 to 6-cylinder in sequential, and 8, 10 and 12-cylinder in semi-sequential. It allows several tunings (selectable by rotator) thanks to its multimapping functions. Evolved strategies of control allow an effective protection of the engine.

    * Data sheet

The Commander66 has been designed for those who want an exceptional ECU. It allows managing 1 to 6-cylinder engines in sequential injection and static ignition, and 8, 10 and 12-cylinder engines in semi-sequential injection and lost sparks ignition. It can manage in-line engines and 'V' engines as well, with a separated management for each bank of cylinders (intake, Lambda, turbos and camshafts for each bank).

Thanks to its high performance microprocessor and its multiple possibilities the Commander66 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).

The Commander66 also manages direct injection if is added a high voltage injectors . See direct injection kit for details.

CONFIGURATION
6 injection channels (sequential injection, semi sequential or direct)
6 ignition channels (static ignition or lost spark)
7 fully programmable auxiliary outputs (including fly by wire 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
8 resistive inputs NTC-PTC-PT200 or logical (of which 4 by CAN-BUS connection)
13 analog 0-5 volts inputs (of which 4 by CAN-BUS connection)
2 selectionnable analog-resistive inputs
1 logical 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

HELP IN THE SETTING
For a fast tuning, the maps of engine start, starter, rise in temperature, 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.

ADVANCED FUNCTIONS OF ENGINE MANAGEMENT
Very advanced engine management functions allow a total optimization of the engine functionment:
Cylinder by cylinder correction of injection and ignition
Assignment cylinder bank by bank for 'V' engines
Correction of richness by wideband Lambda sensor specific for each cylinders bank
Capability to use one intake pressure by cylinders bank
Functioning in two injection rails with gradual shifting from one to the other
Proportional positioning of camshafts
Fuel pressure management
Injection correction by fuel pressure
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

ADVANCED FUNCTIONS OF RPM LIMITER
Rpm limiter on injection, ignition or both
Cylinder by cylinder cutoff with rotation of the first cylinder cutoff (engine protection)
Launch limiter and race limiter, with launch limiter deselection by dashboard switch for road driving
Modifiable rpm limiter following gear position, intake temperature or engine temperature or elapsed time in limiter

ADVANCED FUNCTIONS OF GEARBOX MANAGEMENT
Sequential gearbox management or specific management of robotized gearbox.
Logical or analog switch with definition of the triggering thresholds
The order of gear can be automotive type, motorcycle or special
Intervention time in function of gear position, rpm and engine torque
Intervention at gear shifting on ignition, injection or both, by cutoff and/or modification
Anti jolts procedure (transmissions protection) at gear shifting
Engine re acceleration at downshift

ADVANCED FUNCTION OF CAMSHAFTS POSITIONNING
The proportional positioning can be made on one or two camshafts.
2 intake camshafts for 'V' engines
intake and exhaust camshaft for in line engine
The proportional positioning is executed in PWM with
1 electrovalve for each camshaft for standard management
2 electrovalves for each camshaft for BMW M3 type management (one for advancing and one for delaying).
The camshafts targets can be:
on state mark
on position mark
on one missing tooth
on regular teeth (exhaust only)

ADVANCED FUNCTIONS OF TURBO MANAGEMENT
The turbo management is made by the PWM command of a pneumatic electrovalve of leak or a variable geometry. Wastegates with back pressure are also managed.
1 turbo
2 twin turbos in parallel (1 by bank of cylinders)
2 sequential turbos in parallel
2 staged sequential turbos
3 turbos, with two in parallel and the third serial with both first ones
Turbos in sequential mode are started only under selectable conditions.
Turbo management in pressure or in turbo rpm or both with dynamic choice of the type of management.
For 'V' engines with intake separated by bank, it is possible to read 2 pressure sensors, each allocated to a bank of cylinder, to manage each of the twin turbos with its own pressure.
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 motorized throttle, proportionnal air electrovalve or mecanical throttle opening device
Bang-bang monitoring by exhaust temperature
Bang-bang deselection by dashboard switch for road driving
Programmable injection of water

ADVANCED FUNCTIONS OF DIRECT INJECTION MANAGEMENT
See Direct injection Commander66 kit.

ADVANCED FUNCTIONS OF ENGINE PROTECTION
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

ADVANCED ENGINE MEASUREMENTS
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

ADVANCED PROGRAMMABLE STRATEGIES
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

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

AUXILIARY OUTPUTS
7 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.
