DTC P050B: Ignition Timing Retard Insufficient
.
TECHNICAL DESCRIPTION
•After starting the engine in the cold state, the ECM retards the ignition timing to early activate the catalyst by letting out the high temperature exhaust gases.
•The ECM monitors whether the retard ignition timing control is normal or not.
.
DESCRIPTIONS OF MONITOR METHODS
After starting the engine in the cold state, the retard ignition timing control is abnormal, which is caused by a decrease in idle speed and so on.
.
MONITOR EXECUTION
Once per driving cycle
.
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
•Not applicable
Sensor (The sensor below is determined to be normal)
•Not applicable

Mine is/was probably a 2011 specific issue. After working with Eric (kozmic27) and tephra, our guess was something to do with the timing they added to the 2011 roms.
They added a butt-load of timing at idle apparently to 2011's (disclaimer: I'm not the tuner, I might be saying it wrong). It seemed tuning anything that put it out of that range threw the code on cold-start. We tried adding a lot back in, and it might have fixed it - but it's summer time in Houston. I never really got to see another "cold-start"
I would have sent my info/rom to Bryan to help figure it out as it happened to one of my 2011 RA customers, but my previous tuner (Johnny@JTran Studios) wouldn't get off his butt and send me my stock rom
