I have my own OBD1 device for sale as I no longer need it in my current set up.
Compatibility list available here; http://jfbreton.blogspot.co.uk/2014/02/ ... gines.html
Great for debugging and finding out what all those sensors are reading.
For Android only, uses the TOYOBD1 App
Any questions just ask.
I'm asking just £25 posted (UK only) - Or if your nearby collection is fine.
