N.B.
THE TRIMMER VALUE 0 CORRESPONDS TO THE AVERAGE INJECTION TIMING.
AFTER ADJUSTMENT ENGINES CAN HAVE CARBURETION WITH BOTH POSITIVE AND NEG-
ATIVE TRIMMER VALUES.
THIS IS DUE TO NORMAL PRODUCTION TOLERANCES.
14 - After having modifying a trimmer value, wait
until the CO value becomes steady.
In case of incorrect adjustment, press OK to store
the value in the control unit memory.
YES go to 15
15 - Select «PARAMETERS» and «ECU DATA»
to confirm the new trimmer change has been stor-
ed.
N.B.
WHEN THE CO PERCENTAGE IS RIGHT AND THE CO2 PERCENTAGE DOES NOT FALL INTO
THE SPECIFIED VALUES, THE LAMBDA VALUE IS ALSO DISTORTED. IF THIS OCCURS, CARE-
FULLY CHECK THE EXHAUST SYSTEM FOR ADEQUATE SEALING.
When the CO percentage is correct and the HC (PPM) value exceeds the maximum limit allowed, check:
- spark plug
- valve clearance
- timing system phase
- outlet valves for sealing
When the control unit is replaced, reset TPS and pre-program the trimmer value of the original control
unit (if available) preventively.
In any case, check the CO value again.
