mario_82_ZXT Posted August 16, 2007 Share Posted August 16, 2007 What is the consensus on the settings for running the HEI module for ignition like the sticky? 50% fixed duty dwell with inverted spark output or not? There is also a setting that says "Minimum for HEI 4" but it makes my tach go crazy when I let off the gas under load. I just want this info in the forums because I have searched and found nothing except for one post that says 50% fixed and inverted. That's how my friend's car is set and the HEI runs hot.

trippintl0 Posted August 16, 2007 Share Posted August 16, 2007 Mine is on Fixed Duty, 75%, not inverted. Yes, on the 'Minimum for HEI4' my car cuts out sparks and does weird stuff. It seems pretty reliable on 75%, that's what I've always had it on, with a totally cheap $20 AutoZone module mounted to a ghetto heat sink off an old stereo.

Matt Cramer Posted August 17, 2007 Share Posted August 17, 2007 "Minimum for HEI" is a setting meant for 7 or 8 pin HEI modules, not 4 pin modules. Quote Link to comment Share on other sites More sharing options...
