You'll be fine. Just baby it (low throttle input, no more than 50%) until you need to fill up again. It won't show knock unless you put it under load. So, don't put it under load, then get some 92 or 93 back in it next tank. To be clear, there is no fuel octane sensor- it just reacts to knock and lowers advance between a high and low spark table in the tune until it stops knocking.
