SO i have a 4.8/4l80 combo swapped into a 78 monte. I have it running off its stock PCM with the vats removed, no issues there. however i switched out the stock van MAF for a truck style MAF.

i've tried creating a bin using the 7603.xdf (found in a post here a few months back) as the stock bins with the segments i need are available (added to the post). but tunerpro doesn't seem to like the xdf i found and universal patcher isn't giving me the option to segment swap with that xdf either.

i would appreciate anyone helping me out with what i'm missing? i'm a newbie but i feel like i should be able to figure this out and its driving me nuts.
