After successfully datalogging the trip to work I can see I'm using less than 50% of my old VE/Spark table because the engine doesn't pull enough vacuum to use the lower half of the table. So time for a re-design to give me better resolution in the area I do have vacuum.
So I attached two tables, one is my old one with the MAP/Baro pressures fairly evenly distributed along the y-axis and one I'm going to change too, which has more bins above 60 since this idles at 62 and cruises at 65, and any more loaded up only raises the number (increases the atmospheric pressure in the intake).
So here is my old VE table. The 60 is halfway up the side, so essentially everything below that isn't used except when coasting in gear and the fuel can be cut down quite a bit.
What I'm proposing going to. Which gives me more resolution on the y-axis in the area that I'm actually operating in. (ignore the fueling numbers, they aren't adjusted yet)
So I guess the question is there any issues with setting it up this way? With the 2nd baro sensor I shouldn't run into an issue when I go to lower elevation it shouldn't go much below 60 (MAP/Baro) even at idle or cruise. I'm looking at using the same x and y numbers for the ignition advance tables.
