Vapor dash tacho input
Hi all!,
I am looking to get my head round the wiring (dreading it to be honest) and I am looking at how to get the correct feeds to the vapor dash. The one
which is causing me some head scratching is the tacho input. The instructions suggest wrapping the feed wire around a HT lead. However I am running
a megasquirt and it has a tacho output. Is that tacho output any good for driving the vapor dash? And if not is the wire wrapped round the HT lead a
reliable solution?
Thanks
Chris

Chris,
I have a vapor in my indy and it works great.I had the tacho feed wire wrapped around a ht lead and it worked fine,i have since wired it to the tacho
feed in the ford system.I would give trailtech a call and ask them for advice.Alternatively call rally design,they fit them in cars and know what they
are doing.I have had advice from them before and they are very helpfull.

Megajolt tacho out works on my Telemetrix
The other possible output is from the coil pack using zena diodes, check out the Autosportslabs /megajolt site

I asked a similar question
http://www.locostbuilders.co.uk/viewthread.php?tid=109820
Ordinarily I'd say ring the manufacturer, but I can save you some time - they don't know!
I'll keep my eye out for a solution.
Cheers
Chris 
Note to all: I really don't know when to leave well alone. I tried to get clever with the mods, then when they gave me a lifeline to see the
error of my ways, I tried to incite more trouble via u2u. So now I'm banned, never to return again. They should have done it years ago!
