I'll hardly have the time even to solder something up and program via copy/paste, so hopefully I'll find a few hours soon to try this out.

I'm in an ISO car, with a MAP intake. Looking at the code it looks like the OBDuino automatically converts MAP to MAF (approx) if the MAF PID request doesn't return expected data. So If i'm understanding properly, all I have to do is comment out the #define ELM and I should be good to use the following schematic:

Are you using the mc33290 chip and if so, where did you find it? It looks like digikey no longer stocks it, but they link to a MCZ33290EFR2 equivalent (I think, without looking too closely, it's just RoHS compliant). I think I'm going to order a few of these if this is the right piece.
Cars have not created a new problem. They merely made more urgent the necessity to solve existing ones.
