im curious which tables are best to tinker with to get my idle smoothed out. right now its a lil low and chopy. this is a 6E mask 165 ecm.

 

Raise Idle speed vs Coolant temp a little (bigger cam won't like low low idle), and add some spark timing to the idle RPM, low to mid LV8 - try an extra 3 degrees or so at first (after trying just the idle speed increase).

Could also just do the idle speed change, then experiment with moving the distributor and seeing what works decent (but don't go too far - which is easy to do, just see what it takes to stop getting improvements, and back it down to see where it starts to sound different again, and make a judgement call on where you want it). Then, note how much extra you added (can disconnect the bypass and note new base timing), reset the distributor base timing to where it was before (meaning put the distributor back in the original spot ~6 deg). Then add about that many degrees to your original spark table at the idle area. 20-26 should be good enough at idle.

Also, when done with that, reset the IAC/TB set screw adjustment for best results. Many like to aim for 0-10 IAC counts at warm idle.

Why not just set the spark reference angle-base timing (Tuner Pro) to 8 degrees and just leave the rest alone other than resetting TPS and IAC?
