ECU tied to engine bogging in reverse?
I have a 1993 F150, 302 with E4OD, I've replaced most everything I can think of to address the engine bogging in reverse (TPS, EGR, VSS, replaced the trans filter, tune-up and MLPS). It does not bog every time and seems to do it more when the engine is warm.
I pulled the ECU and opened it up. There was nothing obvious inside that looked burned, damaged, etc. Since it is almost 20 years old and the truck has 197K miles, should I go ahead and replace the ECU as well??

Why not? You've already replaced several parts that are not at all related to your problem. What's one more?
Here are the causes of what you are seeing:
Low trans fluid
Loose/missing internal filter
Leaking internal seals
Worn pump
Bad torque converter
