Your sheet is missing fuel mass which is a critical one. The JB4 includes it. It's also missing RS232/USB which is important for firmware updates at home, data logging, etc. The JB4 and Stage1 both include that. The JB4 also includes EWG. The JB4 and Stage1 do not read MAF. Stage1 doesn't require it and the JB4 alters that signal via the CANbus. The only piggyback connecting to MAF I've seen is ESS. The rest of them take TMAP, MAP, and RPM only.
Also, regarding Dinan, I'm not sure it actually has CANbus or EWG control. A lot of claims are made but someone would need to independently verify it by examining the harness.
BMS warranties their tuners for 12 months.

Thank you Mike! I was hoping people who know what they are talking about would comment on the thread. I'll update everything soon.
