zeroing timing on an FD
can someone please explain this to me. my car runs fine and i never zeroed it. i just did a friends car w/ an e6k and the same thing... runs great. the other night i was at another member's (of the other forum) house and he told me that he has never zeroed his timing either.
when getting my friends car finished up, i was going to go ahead and zero it... but figured i would ask if there is an easy way how to do it. back in the day racing beat used to sell little markers for the 12a's you could use to easily see where differnt timing was by using their tool/marker. i think the little mark on the FD wheel is 20*atdc? is this right? if so, exactly how do i go about making sure the timing is right? should i change the value in the haltech? if so, what value and to what? can anyone help? i have seen tons of info on doing it on a FC... but what about the FD?

nevermind. i answered my own question by going on HitMan's site. (the site was down last time i tried it)
this is what i got from his site.
- 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.
