ok. i was finaly able to get on hitman's site. this is what it said. figured i would post the answer for the records if someone is to search on this at a latter date. 
- the timing check process for these engines is a little different. Some models of E6S and E6K are not adjustable for the timing lock, and some that are cannot be locked to -20 degrees to line up the single notch these motors have at 20ATDC. To do this check we can cheat a little. Start the engine and lock the timing at 10 degrees, this is the default timing lock number for all Haltech systems. Now with a timing light connected to Lead 1 spark plug lead, check where the mark on the disc lines up. By adjusting the Trigger Angle value make the notch line up with the pointer, remembering that increasing the value retards the ignition and increasing it advances the ignition timing. The engine will die down a bit at this retarded ignition which is normal for now. Once the notch lines up turn the Timing Lock to OFF. Look at your Trigger Angle value and now subtract 30 and enter the new number. For example if the timing lined up at 95 degrees, then a new value of 65 degrees should be entered. Now you are done with zeroing the timing. If you are confused you can email HITman and we will try to answer your questions.
The other easy way is to lock the timing at -5 and check the timing with the light on T1. This should be firing at -20BTDC (20ATDC) and should line up with the notch directly.
