The Challenger8 is designed for those who want to conquer thanks to an ultra modern 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 (calculates in 32 bits while many other brands calculate in 8 or 16 bits) the Challenger8 allows to get astonishing accelerations.

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.

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.

 Complete management of the flexfuel with reading of Ethanol content sensor
• Sensor reading inhibition if the fuel flow passing through the sensor is insufficient for a correct reading of the Ethanol content
• Correction of injected quantity according to Ethanol content, engine t°, engine load and engine speed
• Ignition advance correction based on Ethanol content, engine t°, engine load and engine speed
• Specific injected quantity at engine starting according to the Ethanol content and the engine t°
• Specific ignition advance at engine starting according to the Ethanol content and the engine t°
• Specific richness target according to the Ethanol content and the engine load
• Specific turbo pressure and turbo speed targets according to the Ethanol content
• If you need it, Skynam can provide the Ethanol content sensor

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).

KIT CHALLENGER8 ECU

• The kit consists of the Challenger8 ECU accompanied by mounting accessories on the engine. The kit we offer is specifically dedicated to 6-cylinder engines with fully monostatic ignition and sequential injection.

If you need to equip an engine with a larger number of cylinders, you may need to order additional accessories.
In all cases, refer to the kit complements below to check your needs

• The PC connection kit via USB-FTDI is not included in the computer kit. It must be ordered as an option or separately. It is essential to be able to connect your PC to the Advance and Commander computers and make engine adjustments.

COMPOSITION OF THE ECU KIT
• Challenger8 ECU
• Semi-finished engine loom
• Air temperature sensor
• Water temperature probe
• 2 dual ignition modules (8-cylinder monostatic)
• Connector kit

SEMI FINISHED LOOM
This loom is pre-wired on the ECU and driver side connectors, with sensors and actuators connectors not installed.
Its length is to be adapted when intalling on the vehicle, then the sensors and actuators connectors will be wired.
• The connectors of the standard sensors* and standard actuators* that are delivered with the kit are provided.
• The various branches of the loom are labeled (grounds, power supplies, measurements, auxiliary commands, injectors, …) but not sheathed. High quality canvas adhesive tapes are provided to finish the sheathing when installing.

*Standard sensors:
These are the sensors that belong to the engine accessories list.
• water and air temperature sensors,
• atmospheric and intake pressure sensors,
• temperature and pressure sensors of oil and fuel

*Standard actuators:
These are the actuators that belong to the engine accessories list.
• gazoline injectors,
• ignitions coils

CONNECTION KIT
The USB-FTDI connection kit must be ordered as an option or purchased separately.
It is essential to be able to connect your PC to the Meteor86 ECU and make engine adjustments. The USB-FTDI interface is the same as for Challenger5, Challenger6, and Challenger7 ECUs.

KITS COMPLEMENTS
The kits we propose are specific to 4-cylinder engines with full monostatic ignition and sequential injection. To use them with a higher number of cylinders, you will need some complementary accessories.

Here are the main types of ignition you can manage:

Distributed ignition (1 ou 2 coils with distributor) :
Uses 1 single ignition module or 1 dual igition module (included in the kit).

4-cylinder engine lost spark ignition (2 dual coils) :
Uses 1 dual ignition module (included in the kit).

4-cylinder engine monostatic ignition (4 single coils) :
Uses 2 dual ignition modules (included in the kit).

6-cylinder engine lost spark ignition (2 triple coils or 3 dual coils) :
Uses 2 dual ignition modules (included in the kit).

6-cylinder twin plugs engine lost spark ignition (6 dual coils) :
Uses 2 triple ignition modules or 3 dual ignition modules (from which 2 included in the kit).

6-cylinder engine monostatic ignition (6 single coils) :
Uses 2 triple ignition modules or 3 dual ignition modules (from which 2 included in the kit).

8-cylinder engine lost spark ignition (4 dual coils) :
Uses 2 dual ignition modules (included in the kit).

8-cylindres engine monostatic ignition (8 single coils) :
Uses 4 dual ignition modules (from which 2 included in the kit).

For complementary details, report to the installation notice included in the software Pack that you can download from our site.

ECU OPTIONS

Some ECU functions are optional. You will find them here, alone or accompanied by accessories.

Injection self learning function
Challenger8 ECU is able to fill by its own its injection time map, grealy facilitating the engine tuning. This feature is an option that is to be purchased separately from the ECU.

Injection self learning kit and LSU49-5
Challenger8 ECU is able to fill by its own its injection time map. This feature is an option that is to be purchased separately from the ECU. This kit adds a LSU49-5 controller and its wide band Lambda sensor to the self-learning option.
