very good info. that means when you're alternator does **** the bed though you wont know until the truck dies, right?

 

Try a different engine segment on your tune... The composition sensor is a test that needs to be turned off... When i swapped my motor i used a compatible engine segment and it caused some issues.... I downloaded a different tune and swapped the segment and all is welll...

 

X2 Great info thanks for sharing, I will try this!!!

 

Checkd my tune and terminal L and F are already set to not report but i still have the light .

Did you solve your issue bud ?
