has anyone fitted a rev counter to a 680 twin rear axel 2.9 5 cyl? i would like to know what rpm is at 100kph in top gear,it does sound busy compaired to my old 2.8 4 cyl renault which revs at 2800 at 100 kph.
A few year ogo i looked into it,the cost for the unit was £250.00 ,you have to remove the hole of the dash board to remove the cluster.Then fit the R/C then wire it up from the UCU, then go to a merc dealer to have ECU set up to sent the signal to the R/C. Hope this helps
