Subject: NEW FUNCTIONS OF THE ALISEI N ECU
With this bulletin we would like to inform you that as of 02 March 2009 we will be distributing the new version of the
ALISEI ECU.
The new versions will be recognized by the following code on the back of the ECU
“AEB2001NC” on the ECU 3-4 cylinders.
“AEB2568D” on the ECU 5-6-8 cylinders.
The new ECU (electronic centralized Unit) are not compatible with the software previous to the version 5.0.5.1
currently in use, with the old firmware or the firmware currently in use (27.00 for the 4 cylinders.; or 28.00 for
the 5/6/8 cylinders), no longer in use because of incompatibility.
The new ECU works with two firmware that are
- version 5.6 for ECU 3 -4 cylinders.
- Version 3.0 for ECU 5-6-8 cylinders
It is possible to use the configurations used earlier.
PRINCIPLE CHARACTERISTICS
ECU’s derived from the actual model with an additional capacity of OBD management communication on the line
K or line CAN:
Same functions of the current ECU with disconnected OBD
Compatible Pin-out with the current ECU. You need only to add the three wires for the OBD communication.
Use of a new microprocessor with a higher performance than the one current ECU used but they need a new
firmware which is not compatible with the previous one.
Total compatibility with the current configuration
New PC software
FUNCTIONS OF THE ECU WITH CONNECTING WIRES OF THE OBD DRIVE AND COMPATIBLE
COMMUNICATION STANDARDS
Possibility to see the petrol corrections on the interface of the PC
Possibility to disconnect the adaptability function during the functioning by gas based on the processing of the
OBD parameters.
ADAPTABILITY
Recovery of mechanical tolerance
Recovery of repeatability
Recovery of long term – medium stability
Capacity of adequate but limited intervention
Need for a correct mapping (disable adaptability when set up completed)
Control actual gas (“fast”)
Control historical gas (“slow”)
Control of percentage of carburation map
Medium double base (information obtained from the OBD connection)
Adaptability to different quality of carburations
STANDARD OBD CURRENTLY COMPATIBLE AUTOMATIC
RECOGNITION TYPE OF CONNECTION.
ISO9141 K-line pin 7 diagnosis (connection type 1 on the handheld tester)
KWP-2000 Fast Init K-line pin 7 diagnosis (connection type 2 on the handheld tester)
KWP-2000 Slow Init K-line pin 7 diagnosis (connection type 3 on the handheld tester)
CAN standard-250 Kbps CAN-H pin 6, CAN-L pin 14 from the diagnosis drive (connection type 6)
CAN extended-250 Kbps CAN-H pin 6, CAN-L pin 14 from the diagnosis drive (connection type 7)
CAN standard-500 Kbps CAN-H pin 6, CAN-L pin 14 from the diagnosis drive (connection type
CAN extended-500 Kbps CAN-H pin 6, CAN-L pin 14 from the diagnosis drive (connection type 9)
SUITABILITY
All the ECU that manage fast INTEGRATORS / slow “normal” (+/- 25%)
All the ECU that manage fast INTEGRATORS / slow “right”
In the coming developments on all units compatible with OBD
In next shipments the wires for the OBD connection will not be included with the general cabling. They will have to be
supplied separately.
POSITIONING OF THE CABLES
The cables must be inserted in the following PINS
4 CYLINDER ECU
CAN L Pin 6C from the BLACK connector (yellow-grey wires) Pin 14 on OBD connector
CAN H Pin 8A from the BLACK connector (yellow-green wires) Pin 6 on OBD connector
K-LINE Pin 8B from the GRAY connector (green wire) Pin 7 on OBD connector
8 CYLINDER ECU
CAN L Pin 51 from the ECU Gas connector (Yellow-grey wires) Pin 14 on OBD connector
CAN H Pin 54 from the ECU Gas connector (Yellow-green wires) Pin 6 on OBD connector
K-LINE Pin 52 from the ECU Gas connector (Green wire) Pin 7 on OBD connector
NB: When you use the OBD, it is extremely important that during the Tunig is not just checked the
"adaptativity" but should be checked only at the end of development.
CODES OF ADDITIONAL CABLES

For 5/6/8/ cylinder ECU KF2568-OBD
Grateful for your kind collaboration, we remain at your disposal for any further clarifications, and we take the
opportunity to send your our greetings.
