Ok so I am a computer software geek. I have been creating mobile (12V)computer applications in a completely different market. But the idea of adding software to my 914 is really inspiring me. I would love to be able to get OBDII type info from 914 analog sensors installed on stock instrumentation, FI systems and cool third party user components (analog or digital).
So who is doing this? Or is my wife correct... Who cares! Regards, James |

In order for the sensor data to be of value the characteristics of the sensors must be known. Is there any information that gives Bosch sensor ranges? The Bentley manuals only state that the resistance is inversely proportional to the temperature. Or do the sensors need to be calibrated using thermocouples, mechanical gauges, ...?

According to sources I've read on OBD diagnostics, the values are standardized between certain manufacturers on OBD-II systems and standardized between manufacturers for OBD-I systems. I hear there are a lot of variances when dealing with OBD-I. There are free and pay for applications that you get get off the NET that already have these values mapped out. I've been eye-ing this one for a 95 993 system. It's intended for GM products, but he has made a version for an Audi Motronic system that I'm hoping will be very close to the Porsche Motronic. |
