I have the SAE papers from both NTK and Hitachi and they are of no help,
other than explaining how the sensors work. My best hope is an engineer
at Honda who is supposed to get back to me now that I am back from a 10 
day west coast racing trip. I am pretty sure Honda's electronics is in 
the normal car ecu. Whether the car ecu can be hacked or a circuit derived
remains to be seen.
