The Challenger5 has been designed for those who want to conquer thanks to an ultra modern ECU. It allows managing 1, 2 or 4-cylinder aspirated or turbocharged engines in semi-sequential injection and lost sparks ignition.

Thanks to its high performance microprocessor (calculates in 32 bits while many other brands calculate in 8 or 16 bits) the Challenger5 allows to get astonishing accelerations.

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

Selection of hard cut or soft cut RPM limiter. The hard cut limiter allows a modification of ignition advance and injection time for a machine gun limiter with burst of flames.

 An exhaust bang is done at the end of sequential gear shifting because the normal ignition advance is recovered with a slope allowing to avoid jolts in the transmissions.

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

TECHNICAL PRESENTATION

CONFIGURATION
• 2 injection channels (semi sequential injection)
• 2 ignition channels (lost spark ignition)
• 3 fully programmable auxiliary outputs (rpm or temperature relays, ON-OFF camshaft, advanced working …)
• fuel pump management according to FISA regulation
• RPM sensor selectable Hall effect or inductive on crankshaft flywheel
• 1 internal power supply tension measurement
• 4 resistive inputs NTC-PTC or logical
• 4 analog 0-5 volts inputs
• 1 selectionnable analog-resistive input
• 1 differential 0-5 volts input

HELP IN THE SETTING
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 (turbo, air intake proportional electrovalve) are also preset.

ADVANCED FUNCTIONS OF ENGINE MANAGEMENT
Advanced engine management functions allow a total optimization of the engine working:
• Full self-learning of injection time map with display of learning instantaneous quality
• Continuous survey of richness by Lambda sensor (wideband or 0-1 volt)
• Altimetric and/or dynamic pressure correction

ADVANCED FUNCTIONS OF RPM LIMITER AND LAUNCH PROCEDURE
• Rpm limiter on injection or ignition or both together or one after the other
• Soft cut or Hard cut limiters selectable
• 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
• Injection time and ignition advance correction during launch procedure to get high turbo pressure for a cannonball take off
• Soft cut limiter: gradual cylinder per cylinder cutoff, and turning (always begins the cutoff sessions with a different cylinder to avoid always heating the same cylinder)
• Hard cut limiter: all the cylinders are cutoff at the same time, with tunable hysteresis to uncut the cylinders with tunable modification of ignition advance and injection time for a machine gun limiter with burst of flames

ADVANCED FUNCTION OF TRACTION CONTROL
• Traction control by engine acceleration monitoring in function of the gear position

ADVANCED FUNCTIONS OF GEARBOX MANAGEMENT
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 and engine speed
• 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)

ADVANCED FUNCTIONS OF TURBO MANAGEMENT
• Turbo management by intake pressure control
• Management of wastegates with back pressure
• Pressure target tunable according to rpm and throttle (or pedal) position
• Pressure target multimapping
• Bang-bang (antilag system) at the starting up for cannonball launch
• Bang-bang managed with proportionnal air electrovalve or mecanical throttle opening device
• Bang-bang disabling by dashboard switch for road driving

ADVANCED ENGINE MEASUREMENTS
• Every measure has a customizable digital filtering
• For every measure, 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
• Wideband or 0-1 volt Lambda sensor

ADVANCED PROGRAMMABLE STRATEGIES
Extremely flexible strategies allow to multiply the possibilities of tuning:
• Two selectable possible engine tuning by vehicle board switch (for example multi fuels, additives, super boost of turbo pressure, …)
• Addition of engine devices

AUXILIARY CAN-BUS
A completely programmable auxiliary CAN-BUS (11 and 29 bit identifiers, speed until 1 Mbits) allows to send desired data to the others connected nodes, data recording or dashboard.

AUXILIARY OUTPUTS
3 completely programmable auxiliary outputs.
They can be configured in On-Off (programmable hysteresis), PWM from 10 to 10000 Hz or angular (engine synchronous) commands, with adjustable cyclical ratio (and phase), and piloted by any combination of parameters known by the ECU.
It is for example possible to command in ON-OFF, PWM or synchronously with the engine external devices in function of the state of the multimapping switch, race switch, or throttle position, engine rpm, temperatures, limiter type, …
