We used Extra 029v, OEM crank position (CKP) as tach source and TDC input as the Cam input. Used wheel decoder with "no missing teeth" and it started on the first try.
We used a simple 5v signal to the stock Ignition Control Module, but later removed it to use his MSD 6A box (using standard spark output of MS).
Car ran in the Redline Time Attack "unlimited" class this weekend with zero problems, and took home a second place finish!
I should add that this car is running the 029v firmware, but is running one of the first production "Phantom EMS" units from Spectre Performance.
