se mi date i rapporti delle TDCI preparo le tabelle apposite. ( i rapporti sono presenti sui dati ETIS )

Le TDCi dovrebbero avere gli stessi rapporti, cambia solo la riduzione finale al ponte, quindi la caduta di giri è la stessa (per il 1.4 sono sicuro, ma dovrebbe essere così anche per il 1.6).
L'unico diverso è il 1.6 benzina, che ha 3°, 4° e 5° marcia più corte e ravvicinate, ma non saprei dirvi i rapporti precisi.

@Dario60 hai pm

ma questi valori valgono solo andando a benzina o anche andando a gpl?

comunque molto utile la tabella;
considerando che per il motore si sente verso i 3000 giri, si dovrebbe fare in modo di trovarci intorno ai 3000 giri ad ogni cambiata;
-dalla 1° alla 2° cambiando a 5600 ( ) giri ci ritroviamo a 3018 giri
-dalla 2° alla 3° cambiando a 4600 ( ) giri ci ritroviamo a 3049 giri
-dalla 3° alla 4° cambiando a 4050 ( ) giri ci ritroviamo a 3005 giri
-dalla 4° alla 5° cambiando a 3850 ( ) giri ci ritroviamo a 3080 giri

con entrambe le alimentazioni.
SI, visti i dati della tabella sarebbe effettivamente consigliabile cambiare intorno ai 3000 proprio x non far andare troppo sotto il motore, con conseguente scarsa ripresa.

Dario60 ha scritto:
no, io non intendevo dire che bisogna cambiare a 3000 giri, annche perchè cambiare da 1° a 2° a 3000 giri si uscirebbe col motore a 1500 giri

io volevo dire che, la tabella è molto utile per poter tenere il motore sempre sopra i 3000 giri, cioè cambiare in modo da avere in uscita il motore almeno a 3000 giri; così facendo guidare la nostra fofi dovrebbe essere molto più divertente;

non è difficile, basta ricordare i giri a cui cambiare marcia:
in successione dalla 1° alla 5°

> 5600 giri --- 4500 giri --- 4000 giri --- 3800 giri


Ciao

certo, hai ragione, non avevo capito............
naturalmente se la vuoi tenere allegra devi portarti a determinati giri che ti permettano poi al cambio-marcia di riprendere con una certa facilita' .....direi riprendere dai 2800 in su credo vada cmq. bene, poi come sempre le esigenze sono diverse.

beh bisognerebbe provare le varie combinazioni...

sai che bello se tutti avessimo quella famosa freccia verde del cambio marcia e si potesse impostare a nostra esigenza...
