Will a Hall effect TPS work??

Guys, I'm getting started on a carb to injection conversion on my Maxton (first gen stuff). I've got a throttlebody in mind but will MS take a hall effect TPS? Until now, I've only heard of hall effect sensors on stuff like ignition sensors, but it comes with a hall effect TPS. Here's the website for it; Borla-TWM Induction - Throttle Bodies (423) 979-4045
Well, the exact page didn't work but it's a 3002 TB about half way down the page.

ANY help would be appreciated. I've done searches here and on other MS sites but never seen any info one way or the other on if this works.

Typically, the TPS signal is expected to be 0-5V. I don't know what the output of a hall-effect TPS looks like, but I'd expect it to be a series of pulses on 2 channels, and therefore would be challenging to turn into an analog 0-5V signal. Depends on the specific output though

This will produce a variable voltage output unlike a hall sensor on a crank, which would produce a pulse. The pulse is created as the magnetic field passes by the sensor, on the TB the sensor is always in the magnetic field. As the magnet rotates with the throttle shaft, the magnetic field changes relative to the hall sensor. Hall effect sensors produce a voltage proportional to the magnetic field, therefore it is variable voltage. The only thing you need to determine is what voltage range the sensor outputs.

Oh, ok, thanks for that info. I hadn't seen one, so I wasn't sure how it worked. So i guess as long as it's 0-5V, it should work
