Nearly forgot about this install job I did a couple years ago. Complete details listed here: http://forums.tdiclub.com/showthread.php?t=364689
Simple SMD breakout board for retrofitting a higher pressure transducer to an ECU that supplies 5V. Optional components for RC filter to smooth output and an DIP switch for bypassing them if desired. Works w/o RC filter & DIP if desired.
Due to the dim output of the fiberoptic system for the HVAC controls in my car, I've started working on making a custom solution. Time is limited though. I've gone through 5 designs and 3 prototypes, but light diffusion is too poor right now
