Cefiro Clusters

[Traditimeour]

Hi all,

I had to replace my cluster, and now it seems that the speed is wrong, I seem to be traveling slower at "60 " than the rest of the traffic?

Just wondering if the readings can vary between cluster from different models, (Auto/Man, RB20E/DE/DET)

I would say that the issue is not that the clusters have different ratios, but that the cluster is out of calibration due to age.

Cable driven speedometers operate using a spring and rotating magnetic field, when they get old the spring looses it's tension and hence the speedometer reads higher than your real speed.

The cluster between series one and two are different i have one of each they both work tho if that helps.

Yes, there is different reading between auto and manual clusters, I have a manual with an auto cluster. speedo is out by 10 kays, changing the cable fixes it but I forgot which model you need it from...

That is a freakn really good bit of info thanks for that. Is there a easy grub screw or sum thing to adjust in real time wif a GPS to calibrate easy?

It's not something you can adjust yourself, I believe a specialist shop would replace the spring components with new items.

Makes sense about the auto/manual thing considering they usually have different gear ratios between auto/manual, and the speedo cable is driven from the gearbox output.
