Nissan speedo signal

Recommended Posts

Hey there, I need support in setting up my nissan R33 speedo. I‘m getting the signal from a hall effect sensor on my cd009 gearbox into my G4 fury. 

I send the speedo signal via aux4 to the stock R33 speedo. But the needle does not move in neither setup.

is the G4 fury not able to send the needed 12v signal to a nissan speedo?

what can I do?

thanks and regards

Chris

Thanks for the Information, the speed reading in the PC Link software is correct.

The current problem, as far as I understand it is the following. The stock RB transmission speed sender is acting as a pulldown to ground and therefore the cluster is the driver.
By wiring the cluster to the the link g4 (DO4) is the Driver, which won't work because there is no pull down to Ground option...

Am I correct?

Thanks for your help!
Cheers!
Chris

What type of speed sensor does the R33 gearbox have originally?  I have a feeling they are VR sensors, in which case the speedo will be expecting an AC waveform, not a DC squarewave.

Yes, the Dakota thing should work, but try this circuit below first.  It wont make a true Sine wave but it will make a signal that crosses zero volts.

Old thread I know but to result it for others, Nissan Z32 300ZX running a Storm black, the above circuit works perfectly in converting the Link ECU "speedo" DC output to an OEM AC wave form in order to run the OEM speedo.

From this forum lurker, excellent support,

Cheers.
