Dave McCulloch Posted May 24, 2005 Share Posted May 24, 2005 Sorry for all the posts, but the problems are all coming to light... Do I need to "enable" the tacho output on the emerald somewhere? I ran the old engine (on old wiring loom) with the emerald briefly, and the tacho worked - but that simply fed the ignition coil wire to the tacho, as it had a distributor. The new engine is wasted spark, and hence I ran pin 12 from the emerald to the tacho wire in the engine to car loom connector. I've checked this wire with a multimeter and it's fine. The other possibility is I disturbed the connector on the back of the tacho when I was messing with the wiring behind the dash... Dave Link to comment Share on other sites More sharing options...
Myles Posted May 24, 2005 Share Posted May 24, 2005 Not as far as I'm aware. In the Events tab, there is an option for the 'tacho driver' - but ISTR this turns the tacho telltale on or off (the needle races to the max RPM recorded on power-up)... ...you *probably* don't want this though - there's a bug in the SW that can lead to a totally erratic (and intermittent) tacho needle during normal usage - I thought I had a loose connection as the needle would dance randomly - but someone said that Karl had suggested turning the telltale off - and low and behold, it worked!
