MAP/PCM trouble?
MAP/PCM trouble? I'm new to tuning and i have learned some along the way. I hit a wall that I can't seem to fix. The other night while going through my logs that my MAP is reading according to EFILive Scantool. But when I open my tune to cross reference the paused data to the actual tune, my main ve is stuck on the 15kpa column no matter what the MAP says. I have two main questions:
1. Is this a sign of a bad MAP or a PCM problem?
2. If my previous tuner started a SD tune and then stopped mid-tune is it possible to lock the PCM into reading just one column like that? And if so how do I unlock it?

From reading your post it sounds like you dont have something configured right in your scan tool. If I understand you correctly when watching the log in the tune its not changing cells, is that correct? In the scan tool go under data and look at the min and max values and see if your map is working.
