VDO rev counter reading half revs?

[CrashBangWallop]

I apologise in advance to my cr@p description.

I was to told that my VDO rev counter could be displaying half the true rev amount.

It was set-up on my old CVH but, is now reading it's input from the EDIS-4, I think.  Is there a pulse difference... or a setting on the rev counter I can change... or do I need to get a reading from somewhere else?

I'm sure what I'm on about.  Can you tell?

It's not a major problem but, it would be nice to do it correctly.  My rev counter will otherwise read like it was a V8

Thanks,

Neil

DIP switch settings?

Veiwed from the back with the big connector at the top, settings should be (from left to right) 1-up,2&3-down.

If the dip switch settings dont make any difference you can get an Omex unit that doubles the read out. I had to have one after Dennis Vessey re-mapped my Weber Alpha system

Thanks very much.  I'll take a look tonight.

I have a VDO rev counter running with an EDIS 4 module and it reads fine, I wired the tach pulse into terminal 2 of the EDIS4 which apparentley gives a full tach signal although it doesn't seem to be marked on the wiring diagrams that i've seen!

Hope this helps
