I finished hooking up the J&S safeguard on my car this morning and i'm having quite a problem getting it to arm properly. The manual says to go up to highway cruising speed and stay around and dial it down so that it just stops pulling any timing. Well, even at maximum sensitivity, it doesn't show that it's pulling any timing. What's more, it pulls a LOT of timing at low rpms (1500 - 2200) at low to medium load (.4 - .6). How did you guys dial in your sensitivity? What's the best procedure you found for this?
