I've been running a 2 Bar system forever and my MAP sensor recently went out so I moved to a 3 bar sensor. I loaded the 3 Bar OS from the original stock tune and did a write entire. Now the starter will engage for around .5 seconds and then disengage. I've reloaded the original 2 Bar tune and the truck fires right up. The only code I get with the 3 bar is the crank sensor relearn. Here are both tunes for reference. I've tried starting over with a new 3 Bar file and I get the same result. Anyone else ever experience this issue?
