GREATTTTTT!!!!

It's too lucky for you to found Dirk's post.  :D

So to the end the problem is output from revburner is 12v/0v but the speed S13 cluster use +2.5V/-2.5V signal...what a different. I'm too lucky that my cluster use 12V/0V.

Thanks for sharing this to all other pit builders! And wish you enjoy great driving time with your S13 cluster!:)

Yes old Nissan seems to want AC sine

Even though I don't get a smooth sine waveform from Dirk's setup it works. So I guess as long as the signal varies between + and - voltage everything works.
In fact, I requested from Dirk to draw a schematic that will end up at around +-2.5 VAC (the FSM mentioned +- 3VAC to be normal under the troubleshooting/testing section)

I'm sure it would work on +- 1VAC and +-5VAC as well, but 2.5 felt like a good compromise to be sure it would work AND not be harmful for the speedometer :)
It's just a matter of how much signal is sent to ground so easy to customize.

He had a Nissan 100nx cluster and it used the same signal as the Nissan S13.

I'm so happy this finally works. But I haven't yet tried it with the revmeter running at the same time... that may be another story lol :)
