I'm not sure how the ECU handles codes reset through the OBD box. I've found it much quicker to erase all ECU memory by lifting the fuse (6 in the '92) for one second. This means you'll need to drive it for a few miles to relearn any trim changes, but eliminates any concerns about what is kept in memory. Losing power clears it immediately.
