signal converter

[LERMACHINE]

Hello all. I have a question. I am currently putting together a RCR SLC for a customer of mine. The transmission is out of a ford gt and uses a standard ford speed sensor which I believe is an inductive style. Now the gauge cluster unit we are using is a DD2 pro+ which uses a Hall effect sensor for speed indication. My question is, is there a circuit that would convert the inductive signal to replicate the Hall effect signal? I would like to utilize the speed sensor in the transmission so I can keep this looking as factory as possible. I'm aware that an inductive speed sensor produces a sine wave with voltage that can rise up to 20v. The Hall effect sensor with the dash unit is based off of a 5v supply and receives a square wave and is ground referenced. Thank you in advance for your help!

There are two kits here which MAY help: **broken link removed** The speedo corrector and the Frequency Switch.

I have the frequency switch kit and I'd have to look at it. Usually the construction articles are usually available on the Silicon Chip website.

This IC https://www.electro-tech-online.com/custompdfs/2012/12/snosbu8e.pdf can become a basis of interfacing the variable reluctance sensor.

It looks like the gated output is also "open collector" or essentially the same as the hall effect output. The suggested circuit shows pull up resistors, which would be on the ECM.

The IC would be operated at 12 V, but with the pull-up removed, it will interface with the 5V logic of the ECM.
