ICIT (individual cylinder ignition trim) has been on the radar for most of Speeduino's life, but has never been available. A bummer, as the fuel trims (ICFT) and ignition trims are an enabling (codependent) pair that are much more powerful and useful together as a team. Realistically, the percentage of users that can
effectively apply ICFT and ICIT are relatively small. But, if you have sequential to access individual injector control, and the ability to access per-cylinder data, you can use the available fuel trims (ICFT) that are available.
After a needed review of additional features to choose-from, it could well be that other features would take higher priority for a larger segment of users, e.g., possibly a built-in oscilloscope and digital signal analyzer function tied directly to inputs & outputs as a module, for example.
Space is limited in the Mega chip, especially for those that are only used for setup one time, or not directly applied to running the engine. And so selection of features requires care, but it's likely worth a review of
all functions Speeduino currently has, for those that can (with gained experience) be deleted or replaced for better benefit.
While it might be cool to have a Valet function; if it's a choice between running the engine better versus those that don't, or bling or glitter items like bang-bang exhaust noise function, or functions available externally or standalone, the choice becomes quickly clearer.
