Hi,
I've posted this on other boards, but no one has been able to answer! <img src="http://www.zclub.net/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>
I was wondering what the input signal needs to be for the standard 240z rev count/tach, is it simply a 12v square wave? I'm asking because currently my car hasn't got one hooked up. The haltech engine management system has a tacho out, but is a 5v square wave, so I was wondering whether I could just boost this signal to get it to work with the standard tacho.
If not I will have to go the autometer route...
