Ok now that I have to car back together and running, it't time to go back to my quest to move the maf from the 25 pt stock location to a new location F_5800. I finally understood what happens when you use both the bin and it's proper RDT file. I downloaded both the ranger 70mm35lb and the rangerla RDT. Using PCMX I downloaded to the car and although it would start with a little open throttle. It would hesiate at most attempts at throttle movement after start. I went back and using a spread sheet for help aligning the voltages, I substituted my flow numbers into the first four or so spots. The Car ran better, but still hesitates. Thus I have packed a few files in a folder for you to look at. Because of the differences in the RDT's I was not able to use the graph view in PCMX. I made a couple of jpegs to look at.
