Ahhh c'est marrant, il y a quelques semaines j'en ai acheté 2 rouges

Et il y a forcement un ptit gars qui va poser la question:

Tu l'a branché comment ton compte tour?

J'ai une 900, j'ai déjà réussi à voir un compte tour sur mon pc en passant par l'ODB mais un pc sur le siège passager, c'est pas pratique

Si tu veux donc faire un petit tuto de ton câblage, je suis preneur, je n'ai malheureusement pas retrouvé le sujet donc tu parles ...

I've just fitted a rev counter to a Fiat Cinquecento, and it works.

I bought one of the little round rev counters that are branded "Fast & Furious" and have 7 colour LED lighting. I got mine from Ebay for £20 but there seem to be several sources, with various different brandings.

The rev counter works with 4, 6 or 8 cylinder engines. The twin coils on the Cinquecento means that the signal is like it would be from a 2 cylinder engine. The switch on the back selects the number of cylinders, by selecting a resistor.

The resistor for 4 cylinders is 380 k ohms. The one for 8 cylinders is 190 k ohms. It is the one arrowed in the photo. I changed that to 760 k ohms. To do that I had to carefully prise the bezel off the rev counter. Then I removed the circuit board by unscrewing the brass bolts. I used a soldering iron to change the resistor, and put it all back together. I folded the back edge of the bezel back behind the lip on the case. It's not very neat, but not very visible when fitted.

I then wired the rev counter exactly as the instructions. It needs ground, permanent power, ignition power and lighting input. The coil input is wired to connector 19 on the ECU, which connects to one of the coils. The plug that connects to the ECU unscrews, so it is easy to add another wire there.

The other photo shows it fitted, with the engine on tickover. There is a bit of wobble on the needle at tickover. The rev counter reads half of that on the 4 cylinder setting. It is of course set to the 8 cylinder setting, which is now adjusted to 2 cylinders.

I had to slighly notch out the plastic bracket that supports the speedo to clear the rev counter.

I hope this is useful to anyone who wants a rev counter.

mais j'ai trouvé ceci sur un forum anglais à propos d'une CINQUECENTO (899 cm3 ?):
il semblerait que les 899cm3 ont une "double bobine d'allumage",
( quelqu'un peut confirmer ? )

aller Nounours, voila un truc qui te conviendrais
