[1BadAction]

009F seems to be the byte used in 0E for the MNP switch.

L5453 FDB $009F ; 59, PATTERN, MNP PATTERN
;
; b7 (not used)
; b6 (not used)
; b5 (not used)
; b4 (not used)
;
; b3 1 = ILLEGAL PATTERN REQUESTED
; b2 1 = 'MANUAL' PATTERN REQUESTED
; b1 1 = 'PERFORMANCE' PATTERN REQUESTED
; b0 1 = 'NORMAL' PATTERN REQUESTED

there aren't too many places where it is stored to.... DTC77 also is applicable to it.

i can't find any applications from the factory that used it though, so finding out the pin scheme required is going to be interesting.

I've wanted to do this on my 7060 ($D8).. The bin has tables and LOOKS like it would work, but no clue how I would go about tracing it down. I'm also working under the assumption that it would be a momentarily grounded pin that switches between the modes. Guess I could start grounding random pins to see if my shift patterns change. (quick, someone invest in reman 7060s)

I guess I just can't shake the idea that there is a completely setup tow/haul mode in my factory ECM that I'm not using. Although I suppose it may be something vestigial that never was completed.
