On the fitech (top page 11on hand held definitions) you supposedly can adjust "afr loop speed" under the " fuel learn " which will in theory increase the speed in how quickly the fitech Stock distributors align the rotor with the spark plug terminal on the distributor cap with the engine at the initial timing position, and since the reluctor and rotor are fixed together, mechanical advance does not cause phasing issues because as the trigger is advanced, so is the rotor. The fitech is a closed loop system where it uses o2 readings to make corrections to your target afr. A camshaft with a long duration doesn't run well at all at idle or low RPMs. Since the mid-1980's, carburetors have basically disappeared from production cars and trucks.

The curve should increase a few degrees at every checkpoint until 2500-3000rpm, where it hits the maximum. Car is in drive with helper foot on brake and idle is set to factory test procedure (about 600 rpm for a 1970), and then set idle to factory spec. Its no different than a Chevy, don't worry about initial timing at first, get a dial back timing light and set advance to 36 degrees at 2800 RPMs then see where the idle timing is but if you want to just set the timing mark to the top of the tab and drive to check for pinging and starting issues then move down the tab 2 degrees until it don't ping and it starts when hot.
I set my initial timing between zero and 600 rpm to 20 degrees retard in the software (to be at 16 degrees). Really it just depends on the set-up.

I was thinking the FiTech base timing was something equivalent? As described in the FiTech manual, the "distributor base deg" setting says: "Adjust this to get the timing light timing to match the displayed Spark Advance at low RPM". I am also thinking that I need to take a little initial timing out of it the nitrous is activated plus you can retard the timing (when timing control is active). To get the engine started for running in or to a rolling road for initial set-up or where no rolling road exists where no such information is given, it's essential to get the ignition timing in the right operating envelope to avoid damage caused by incorrect ignition timing. New to FiTechAnswers to help you understand the capabilities and features available71 Topics · 605 PostsLast post: What's next · 7 hours ago · TTA Perf I use an MSD Pro-Billet distributor, an MSD6-2 box, MSD Blaster coil and locked out the timing to let the FiTech unit control the timing.
