Thunder FD rx7 wheelspeed sensors

[cws_nz]

Hi

anyone have experience with the FD wheel speed sensors 

currently mapping out IO for a thunder running an FD RX7, wanting to  pickup the front & rear wheel speed sensors (abs has been deleted)looking at the stock VR abs sensors wired direct to ecu, hoping these wont exceed the max input frequency and was wondering about the minimum pickup speed to  have them reading (drag car build looking to measure slip front to rear for traction/launch control) 

are we better to run a VR to hall converter like this https://msel.co.nz/dmcd-dual-mag-to-hall-converter-gp/

or some sort of pulse scaler to not run out of input frequency?

anyone have experience with the FD wheel speed sensors 

 

edit, I see adamw  has referenced these before for abs sensors  https://shop.vems.hu/catalog/hall-p-162.html which look like a viable option for frequency divider

As you have a Thunder, you'll want to use Digital Input 11-16, as these are capable of 6500Hz input.

Can't advise on the rest, I'm afraid!

I just looked at a log from our FD race car, 3 wheel speeds start working reliably by about 20kmh, the 4th one not until 30kmh.  Possibly the air gap is a bit bigger on that one.

Thank that should work well enough for us, @Adamw do you  know if this is the VR sensors wired directly to DI or do they have a VR to  hall signal converter?

They are wired direct.
