That's my project. I have developed a device which have two functions (you can use each one independently)
1- Convert older and non-standard protocols to OBD2:
KWP71 (BMW, Opel/Vauxhall, Porsche ...)
2- Digitize analog sensors and encode them into OBD2 format
Up to four generic analog sensors, and one input reserved for thermocouple EGT. More than 40PIDs/sec logging rate.
Any ELM compatible device can be used to catch this data.
The electrical connections are quite simple:
input : K-line, sensors & power
output : CAN
Before implementing all features, I need some feedback about the device.
Waiting for your comments.
