This ECU does not replace fully the Challenger4+ in the range of our ECUs

It is specific for 4-cylinder aspirated engines (throttle/rpm only)

It has a very attractive housing for the complete kit

Its main characteristics are

-         Based on a very power full microprocessor for astonishing accelerations

-         Semi sequential injection

-         Lost spark ignition

-         Very effective self-learning of the injection time map (on option for non-professional licenses)

-         2 engine tunings selectionable while engine is running (multimapping) by switch at vehicle board

-         3 launch limiters selectionable by rotator at the vehicle board

-         Race limiter without jolts

-         3 fully programmable auxiliary outputs (rpm and temperature relay, three-state rpm relay, advanced programmation Commander type, …)

-         Sequential gearbox with cutoff time from gear position and engine rpm, with go back slope to normal advance at gearshift end (bang at gearshift end))

You will find its full presentation on www.skynam.com and its software installation with all the tuning documentation.

CHALLENGER5 ECU SOFTWARE

The Challenger5 is an engine management ECU with a very high computing power.
It is specifically made for racing atmospheric 1, 2 or 4-cylinder engines.


 

FEATURES

Chal5_ENU-1.1.0.0.zip is the first software pack for the management of the new Challenger5 ECUs.

Injection:
• Self learning of the injection time base map (needs a professionnal license, or on option with a special Tuneware for standard licenses).

Multimapping:
• a multimapping switch allows two engine tunings. The tuning switching is allowed while engine is running.

Launch limiter:
• 3 launch limiters, selectable by a rotary switch on the vehicle board, allow to get the best adaptation to the road grip.

Sequential gearbox:
• Slope to go back to normal ignition advance at the end of gear shifting, (bang on gear shift end).

NEW FEATURES AND IMPROVEMENT

Intake pressure filtering adjustment:
• This filtering removes pressure instabilities in the intake manifold.
• The intake pressure filtering adjustment is accessible even without a professional license.
• Possibility to select the old way of shifting on slower or less precise gearboxes.
Very important: See the document 'Pressure/rpm Atmo Turbo and bang-bang' which gives a very detailed explanation of how to filter (averaging) the intake pressure to avoid instabilities and what the problems are if this is not done correctly.

Dynamic advance at tick over:
• Dynamic advance limit memorization.

Improved engine starting:
• Added corrections at engine start and engine temperature of the intake air solenoid valve position.

Improved coil loading time:
• Coil loading times accept up to 15000 µs and no longer vary when we return to their calibration.

Improved injection and ignition display:
• Real-time display of the corrections made on the advance and injection time by engine t °, intake t °, atmospheric pressure.
