Valeurs OPCOM au ralenti...Peut etre probleme débimetre?accoups en 4eme?

(1/1)

Benoit74160:
Bonjour à tous j'ai un petit soucis d'accoups en 4eme, c'est léger mais un peux embettant.J'ai relevé mais valeurs de bock à l'OPCOM et je pense que mon débimetre me joue des tours déjà au ralenti....Normalement il me semble que la valeur au capteur (Mass Air Flow Sensor, donc débimetre ) doit etre égale à la masse calculée, hors moi j'ai 6kg/h d'écart......d'autant plus qu'au ralenti ca doit tourner à 25kg/h et moi j'ai 40 et 46kg/h.
L'ecart de la Boost pressure et de la command me titille aussi..............je mets les choses qui m'intrigue en rouge
Voici mes blocks quelqu'un aurait il des mesure de sa voiture au ralenti sous la main?
