Untouchable 0 Posted October 4, 2008 Hallo there... I need a little bit of help. I change my G60 tacho from analog to digital, from the newer G60 with also the vacoum. All working ok with a little bit of modification in the new loom.... except the REV METER!!! When engine starts rev is going UP - DOWN. On loom U1 and U2 is it the WHITE one the REV? As far as i search here and also in the net, i can't find an answer. Im sure 99% that rev moves from the coil pack, and mine is the old style like a cylinder. Any help please?

dirtytorque 0 Posted October 6, 2008 the vdo guage will not work properly from just a digital pulse. It is expecting to see a large voltage spike that would be induced by the coil. On a later g60 it not as ssimple as just hooking it up to the coil directy either.You have to mak sure it sees the right voltage by placing some resistances in series to the guage. On a late g60 the vdo tach is fed via the ecu. Quote Share this post Link to post Share on other sites
Untouchable 0 Posted October 14, 2008 Good! I find out in the german corrrado forum this detailed guide "how to" but is in german lang. I don't know german, and on online translators there are no good results. If anyone here can translate it will be great! here is it http://rapidshare.com/files/153852691/Umbau_Auf_Digitaltacho.doc Quote Share this post Link to post Share on other sites
