NEW FEATURES AND IMPROVEMENTS

Display scope of flywheel and phase teeth
• Allows an easy test of flywheel and phase teeth for engine synchronization.
See new document ‘Challenger8 Engine flywheel and phases test – V100’

Improvement of turbo pressure protection
• The ECU can gradually cutoff the cylinders in case of turbo pressure exceeding

Improvement of the possibility of manually modifying the mini-maxi calibration of motorized throttles
• In case the throttle does not have strong minimum or maximum mechanical stops, the electric motor exceeds the normal min and max positions
• When exceeding the normal maximum opening, the throttle gears are forced and the teeth of the plastic gear wear and destroy over time.
See new document ‘Challenger8 Fly by wire – V110’.

Possibility of using Innovate wideband Lambda modules(V120)
• but these must be programmed specifically to be adapted to Sybele ECUs.
See new document ‘Challenger8 Use of the Lambda sensor – V120’.

The document ‘Use of the Lambda sensor’ provided by the Challenger8 ECU installation must be V120. Version V110 gave incorrect information on the programming of the Innovate modules. Version V120 corrects these errors. But you can also download the CORRECTIVE DOCUMENT by clicking here.

LAST SECURITY CRITICAL MODIFICATION DONE

Not needed.

NEEDING Winjall V9.9.0.0 (see specific downloading)

V9.9.0.0 or later version of Winjall software must mandatory have been installed first.

HOW TO UPGRADE TUNEWARES

• Download new .zip Challenger8 software pack file and save it in a directory on your hard disk.
• If you have already installed a former version of this pack, you have to usinstall it before installing this new one:
In Windows XP, execute ‘Start/Parameters/Configuration/Add-Remove programs’.
In Windows 7 and latter versions, execute ‘Start/Parameters/Configuration/Programs and features’.
In the software list, select Challenger8 then ‘Uninstall’. Follow uninstall instructions.
• With the files explorer, double click on the downloaded software pack .zip file, then double click on Setup. At the question on files extraction, answer ‘Extract All’.
• If the installation does not automatically start: in the new directory created by the extraction, double click on Setup (application).

VERSIONS HISTORY
(Improvements are added from a version to the next one)

Throttle/RPM : V120 (System V120)
Pressure/RPM : V120 (System V120)

1) Possibility of using Innovate wideband Lambda modules but these must be programmed specifically to be adapted to Sybele ECUs.
2) Possibility of manually modifying the mini-maxi calibration of motorized throttles:
In case the throttle does not have minimum or maximum mechanical stops, the electric motor exceeds the normal min and max positions
When exceeding the normal maximum opening, the throttle gears are forced and the teeth of the plastic gear wear and destroy over time.
3) Smooth out jerks during foot lifts and rehitching:
particularly useful with multi-throttle engines which give significant jolts in these conditions.

Throttle/RPM : V110 (System V110)
Pressure/RPM : V110 (System V110)

1) Memorization of performed engine protections.
2) Improvement of fuel pressure protection.

Throttle/RPM : V100 (System V100)
Pressure/RPM : V100 (System V100)

Version 100 is the base version of the new Challenger8 ECUs.
