OBDII Codes and Custom ECM Programming

[jsawduste]

Converting my stroker YJ to OBD11 in order to take advantage of the ECM reprogramming that is now available. Think Ryan for this cause. Going to change the fuel and timing mapping for starters.

What I am looking for is a list of OBD11 codes that will set a check engine light. Not all codes will. Some are simply set to memory while others will throw an immediate hard light.

Michigan doesn't have any emission laws so all that junk can be tossed and the new cal can be set to turn off an EVAP code for example but there are codes like battery temp that I don`t know if it will set a code or turn on the light.

Anyone have a link or chart to what turns on the light vs. sets to memory ?

That way I can pick and choose through the new cal.
