Mine is a 1991, 7.4L, 4L80E, 7060 with a BAMS bin / $D8 mask
This is in a P37 chassis and is a very conservative tune, if you would like a copy of the "as stock" bin let me know.

I do have the Ostrich 2 emulator so I am planning to use the street dyno to figure some of this out... hints would be greatly appreciated. I am trying to tap into the accumulated knowledge of the group...
Thanks, I didn't think the second character W fit the time line and made me curious.

Although as I have said before I only run open loop cause it makes the motor happy. I start off with the block 20-70 map and idle-2500 rpm and data log data log data log with history. I then fix it cell by cell until it runs exactly how you want. Then branch to more rpm and map. For timing I have found with my mod motor it didn't like having a lot of knock retard capability. So I stopped letting it and ended up actually adding timing in the high map/high rpm area. Once again data log and history for knock.
