THE CHALLENGER7 IS FULLY COMPATIBLE WITH THE OLD CHALLENGER4 AND CHALLENGER4+ WHICH ARE NO MORE MANUFACTURED AND SUPPORTED, TO AVOID YOU TO BUY A SECOND HAND ECU WITH OFTEN THE BAD SURPRISE TO RECEIVE BROKEN ELECTRONICS OR IN BAD CONDITION.

IT IS MOUNTED DIRECTLY ON THE CHALLENGER4 (+) LOOM AND YOU IMPORT THE TUNINGS FROM THE CHALLENGER4+ WITH A SIMPLE CLICK.

It has been designed for those who want to conquer thanks to an ultra modern ECU. Like the Challenger4+, it allows managing the 4-6 and 8-cylinder engines in semi-sequential injection and lost sparks ignition and allows in more to manage the 4-cylinder in static ignition. It also manages the engines in distributed ignition.

 

IN ADDITION TO THE CHALLENGER4+

 Thanks to its high performance microprocessor the Challenger7 allows to get astonishing accelerations.

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).

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

HELP IN THE SETTING OF A NEW ENGINE
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 (fly by wire, proportional camshaft, air intake proportional electrovalve, turbo) 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
• Cylinder by cylinder correction of ignition in mode static ignition
• Operation in two injection rails with gradual shifting from one to the other
• Proportional positioning of camshafts
• 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
• Cylinders cutoff with rotation of the first cylinder cutoff (engine protection)
• 3 launch limiters, selectable by a rotary switch on the vehicle board allowing to get the best adaptation to the road grip. Gradual limiter shift from launch limiter up to race limiter to avoid wheels slipping at vehicle take-off
• Race limiter

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)
• Engine automatic acceleration (autoblip) and ignition cutoff at downshif

ADVANCED FUNCTION OF CAMSHAFTS POSITIONNING
The proportional positioning is executed by a PWM command with selectable frequency.
The camshafts targets can be:
• on state mark
• on position mark
• on one missing tooth
• on one supplementary tooth

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
• 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 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 failure, a strategy of replacement value in case of failure, or to use the standard strategies supplied by the ECU
• Wideband or 0-1 volt Lambda sensor

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

AUXILIARY OUTPUTS
5 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 race switch, or throttle position, engine rpm, temperatures (On-Off or gradual speed fans), limiter type, ...
