flywheel tachometer?

If you're willing to spend a $100, I saw earlier in the post, dakota digital will adjust the w signal from the alternator to run your gasser tach.  I though about fiddling around with magnets or using the teeth on the flywheel, a lot of that ends up being problematic as this post shows. 

It really isn't that bad. It takes me 2 minutes to glue a magnet back on. Once I figure out the best glues to use, there won't be any more issues

so, i need magnets then..

I thought your tach is working already??? Why do you need magnets?

my AUTOMETER tach works with a simple magnetic pickup.. my VW CE2 does NOT however.. it will be needing magnets..

Have you thought about doing things to up the output of your magnetic sensor? The first that comes to mind is try a new sensor. Low output is a typical failure mode. The next thing that comes to mind is to decrease the gap between the sensor and your "reluctor". Magnetic ignition pick ups usually are gapped at .010-.015".  Making the edges of your reluctor sharp will also increase the output, as well as making the valleys lower between the "points". Perhaps making the nuts taller so that they stick out father from the pulley would help. I understand that you have some space constraints. I am planning to use a similar set up on my LBGTD.

If after changing to magnets, and you have adjusted the gap to be the smallest possible, and your CE2 cluster still does not work, PM me and I will tell you what mod you have to do to your cluster to make it work.

How about just posting the mod since I will be dropping an AAZ into an '86 GTI sometine in the next week or so and a functional tach is at the top of my list.

cause your 86 doesnt run CE2 wiring, DUH...

the 86 uses a CE1 cluster, witch gets its signal right from the coil..

the CE2 cluster gets its signal from the digifant ECU..

CE1 and CE2 clusters are TOTALLY DIFFERENT dude..
