Yes and I was mistaken earlier, it's Fast355's $od that's working better for me. I'm still goofing around with it though. Still not up to par. I'm about to do some more investigating on $31. Apparently it was made in '94-'95 for the 5.7 Ks that were deemed HD. Mine has RPOs that could have designated it HD. I'd really just like to know what the differences are between $OD and $31. Probably just fatter fuel tables down low.

I think $31 was for HD that had 4l80e trans. Are you using vss? Although there are work arounds od, oe and 31 won't be real happy without vss.

I don't. I've been doing my homework on them. I gather that the cable adapter type works best. I figured I could tune it to run/idle before working on the VSS part but, I've read in a few spots that it's best to get it in before tuning.Originally Posted by myburb
I went hunting and found another '7427 with a stock BCC BJLF. Had the MEMCAL too. So at least I know I am starting with a proper match with my mask. I think I am going to stick with the $OD. It seems to have the most options

Stick with $0D, perhaps look at the timing table for BNKM which is the 1-ton 350/4L80E van. IIRC it is a $OE file.
As for the speed sensor the newer PCM only needs the speed signal input into the 2,000 ppm input if you are running without an E-trans. That means your vans stock VSS signal can be plugged right into the PCM and good to go. You need to disable the Computer Controlled Automatic flag in the options and Enable the TCC ONLY flag.
I couldn't find this option. Am I going blind too ?
