CHALLENGER4+ ECU KITS

• The kit is made of the Challenger4+ ECU supplemented with accessories to install it on the engine. The kit we provide is specifically designed for 4-cylinder engines with lost spark ignition and semi sequential injection.
If your engine has a higher number of cylinders or a different type of ignition, you will need to purchase some complementary accessories.
In any case, report to kit complements below to verify your needs.

• The RS232 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 Challenger4 ECU and tune the engine.

*TWO LOOM TYPES ARE POSSIBLE

Semi finished loom
This loom is pre-wired on the ECU side connector, 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.

Finished loom
As every application is different, there is no standard finished loom:
You have to contact the Skynam technical service to detail the complete making of your loom (see contact page).
• The loom is completely sheathed with braid sleeving.
• The lengths of the various branches are standard (2 meters) or customized (lengths provided to Skynam).
• The connectors of the standard sensors* and standard actuators* are installed.
• The connectors of the other sensors and actuators are to install or are to provide to Skynam.
• The fuses and relays bases are installed if required.

*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

KITS COMPLEMENTS
The kits we propose are specific to 4-cylinder engines with lost spark ignition ans semi-sequential injection. To use them with a higher number of cylinders or different types of ignition, 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 (from which 1 included in the kit).

6-cylinder engine lost spark ignition (2 triple coils or 3 dual coils) :
Uses 1 triple ignition module or 2 dual ignition modules (from which 1 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 1 included in the kit).

6-cylinder engine monostatic ignition (6 single coils) :
Uses 2 triple ignition modules or 3 dual ignition modules (from which 1 included in the kit).

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

8-cylindres engine monostatic ignition (8 single coils) :
Uses 4 dual ignition modules (from which 1 included in the kit).

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