Nissan 200sx s13 ECU controlled cluster, will it work?

GREATTTTTT!!!!

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

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
