Can't get cylinder balance test to work, get code 77 "System failed to recognize brief WOT during Dynamic Response Test (user error)."

I let the KOER test run its course and within two minutes hit WOT and got code 77. After those codes came up, I hit WOT again and then got no codes even after five minutes. What am I doing wrong?
