Timing is infinitely adjustable in Speeduino, and is much more flexible than a box like the MSD. With TunerStudio and MegaLogViewer on Speedy, you can change timing in any increment, for the whole table or one cell, or any selected cells in-between. Setting timing at any given point is through results, and those are shown in gauges and traces as your feedback. The feedback you are focusing-on is indicators of improvement in efficiency.
That efficiency is demonstrated by positive changes in output (torque, HP, etc), or BSFC, economy, response time, or a variety of other feedback data such as MAP level. While you can see some of this in real-time gauges, or in time intervals (increase in speed over time (RPMdot), or speed/RPM over fixed distance, etc), or most usefully in recorded logs (allowing overlay and comparison to the last run); the point is to give the engine what it wants, and using the data to know the tuning direction to take and the peak when you get there.
"Sounding" or "feeling" more powerful (?) is one data point. To be efficient in finding actual best settings, data from many points is preferred, and in a way we can compare and analyze. That's in the programming software (TunerStudio and mostly MegaLogViewer), and with controlled and methodical changes based on comparative test results. Using the Spark Table for timing adjustments allows us to do that, simultaneously with changes in torque, fuel, etc, and in-conjunction with all the other data simultaneously.
I've used knobs in the past when it was all carbs and mechanical FI. A knob was better than stopping to pull-out the wrench and turn the distributor in days past, often just to keep-up with weather changes at the track. The ECM automatically does that for us now. We can do it all from the seat or bench or even track-side and all in one program environment, where it's all tied-together and one click is one degree (or whatever you select) on specifically-chosen cells without moving from the laptop to a dash knob and back.
Most tuning adjustments and settings are done while I'm sipping on a cup of coffee, and while I'm comparing feedback data. Just IMO, keeping it all on the same screen and control works better.
