Well, it works as far as I get a signal from the sensor on a multimeter.
I ordered uprights from T3 4-5 weeks ago and they get here Monday, so once I have them I'll be able to finalize the ring and sensor mounts. My car is currently in the air and I have a turbo engine waiting to get bolted to a still-unsourced CD009 and swapped in, so it might be a long while until I have the inputs actually working with an ECU.
