Will do. Did yours start throwing codes right after installing the new tune?

 

hows the weather? when it starts to get cold here mine will throw a code for the 02 heater sometimes.. just part of having a modded truck

 

Right now its cold. However it started throwing codes when it was still mid to upper 60's out.

 

Swapped in the new tune today, and so far no more problems. Drove about 150 miles then let the truck sit for a few hours, fired it up again and still no check engine light. Think this may have solved the problem.

 

Was the tune updated to remove the codes???

 

No, it was the same tune just a different ECM.
