SW Tach reads incorrect with MSD box - 07/03/10 02:37 PM

I have an old Stage 3 Steward Warner Tach and it does not read correctly. I have a MSD 6al box.
Am I doing something wrong or do I need a different tach with the MSD box.

You need a MSD tach adapter,which I don't think MSD carries anymore.

MSD still manufactures 3 or 5 differnt tach adaptors that I'm aware of, but not sure which one you need.....they usually range from $35-$60 depending on which model

I think a couple of them are over $100 actually!

If you look at them at Summit online you can see the specs and description to help pick out which one you need. The lowest cost one was what I needed to get my Rally tach working correctly.

I believe the one he needs for that tach is MSD's 8910 Adaptor, they run about $35

The one I used when I ran the SW stage III tach is not carried or made by MSD anymore.I'm thinking the 8920 would work??
