7.3 NOTES CONCERNING THE LCS A1 V05
PROGRAMMATION
The standard emulation of the lambda sensor is
settled as TYPE OF LAMBDA
SENSOR
EMULATION
Ì
SQUARE WAVE. This kind of
emulation is used for the main part of the vehicles
and must be changed only if allowed from the
TECHNICAL MANUAL LANDI RENZO MT012.
The lambda sensor emulation of vehicles with
Monoinjector Bosch
(for which the parameter
TYPE OF TPS
Ì
MONO BOSCH) is made
programming
the
parameter TYPE OF
EMULATION
Ì
GROUND. On this vehicles the
yellow-blue wire of LCS A1 V05 must be
connected to the wire n. 2 (and not to the wire n.
4) of the TPS connector at side of the throttle
body.
