BTW, what do you mean with the "latest timing curve"? What does it idle at and where, what, RPM, and how much total timing does it have a what RPM also? I have no clue on the new gen 3 hemi ignition parts or how they are set up Good luck, let us know your results
I was programming different curves into the MSD ignition controller to see if it would help. The current ignition curve 0-900 rpm ramps to 28 degrees. 900-3100rpm is 28 degrees 3100-5000 rpm ramps down to 24. The best idle I have so far is 1350rpm in neutral and 1000 in gear but it was running on the primary transfer slot. Engine will not idle with both transfer slots closed.
