We have been working on our own controller design.
The two output Bosch TPS is a direct connect, and allows us to use two 8 bit ADC channels and still get good resolution. It also provides the potential for a software cross-check, which we should probably add at some point. The Bosch TPS has multiple wipers over the surface to avoid "skips" from dirt or vibration-induced wear-through, but it could still happen.
