You can use a knock sensor as well but it will pick up knocking (detonation) but that is after it starts knocking which is what I don't want to do. With the knock sensor it tells me 2 things. Knock or no knock. Using the EGT sensor will give me a gauge to tell me how close I am to the line without going over.
IIRC based off my old dyno sheet at cruising the AFR on my '83 was about 16:1
