Default Check engine lights keeps flashing can't get codes

Hi, I have a 1985 corvette with a bunch of mods, and I was doing a data log a few minutes ago for my tuner, and I noticed that the car strangely wouldn't go above 4k RPMs, it was bogging, I revved it a little bit and it backfired. Got back to the shop and I revved it up and it backfired and wouldn't rev up high. I noticed the check engine light was on. So I went to go pull the codes and the light just keeps flashing continuously, no pauses just straight consistent flashing.

Does any body know what the hell this means?

I was thinking that before I read the second post. The SES light will flash at different rates to tell you if you are in open loop or closed loop mode.
