I haven't had a chance to work on this. It will be a winter project. I just had my knee operated on and had a ton of stuff to get done before I got laid up. I am also waiting on a manufacturer to release a compiler I want to use.
I met a young guy from NJ who's already done it, he has a page on youtube and FB but I don't know any more beyond that. I think he sells the boardsI have cracked encoding of the output data stream on the Renix ECUs. I have been thinking of building a Raspberry Pi based reader with a 3.5" color touch screen device you could mount in the cab. You could then display any of the readings. For instance you could show an analog type tach display, or any of the other available data in real time and switch back and forth. You could even set alarms that would flash the screen colors for things such as an O2 that is out of range. It could even show you if the ECU was in open or closed loop mode.
Before I spend a ton of time polishing the user interface, are there any people out there who might be interested. My hope is to keep it well under $100.
A follow on product would have a 7" touch screen and have GPS and moving topo map display.
