My tune,....is that the o2 goes to Sleep/freezes up. this is the problem i'm fighting and can't "tune until i give up on the LM2 or fix it.
cuda will set all winter and start right up the first time i try in the spring.
Do you have an alternator on the car and what voltage are you seeing it charge the battery at? Contrary to popular belief you can tune an engine without O2's
