This morning but I read and wrote back to a black box 4 plug ecm with service # 16263494 in vehicle this morning. This was with a gm mdi wireless..

Are you trying in vehicle? If so you might need to make up a bench harness. Also if aftermarket radio or remote start you could try pulling the fuses/removing the data line wire from either one of those temporarily to see if that helps.

Here's a couple.. Go ahead and download it, probably gonna remove it after a day or so just because.. No corvette but I think there is a camaro.

Not sure how your doing that, with 23 requests? Not sure if your low speed vpw or gm lan comm??
650 byte size sounds almost like a mode 23 request size I was getting reading bcm's and ipc's but it sounds too small for total eeprom read?
