ECU Wheel Speed Sensor vs. Stack Speed Sensor - same size?

The Oily Bits S1 Specific Topics

Do Exige s1’s have an ECU sensor on the RR wheel? My S1 USA track car did not ship with it.

My question to those of you that have it: is the diameter of the sensor the same as the LR wheel speed sensor? It is literally the same dimensions, just a different mission given to each?

I found a mug shot for comparison: scroll down in this Exiges Feb 2015 post:

2nd to last pic at bottom, ECU mount is the on the right - the two look identical in size - but maybe the Exiges community knows different?

Why am I asking? My quest is four wheel speed sensing plus Yaw into my mongrel Stack 8100M / DVR / 8903.

Thanks All, especially those who have their cars in pieces.

I have the sensors out but gave the Ali to some to make a new set (in July last year). I’ve text him, hopefully hear back soon…

I have the sensors here but I’m unsure where to measure.

You have the sensors handy? that’s perfect. Measure the diameter of the circular bit as shown this this piccie - this is diameter of the LR wheel speed sensor mount.

If you could measure the diameter of the fat round bit of the sensor that fits into the alu mount, I am grateful.

The LR sensor mounting hole is ~20.5mm, the sensor itself is say 20.3mm or so, hopefully you’ll find both are the same diameter.

Any good?

Edit, when I took them out…

Perfect. Thank you very much. Kinda funny how they’re fractionally different, but its no issue.

Good luck in your refresh - great to see it has been driven - hopefully by you.
