Wondering a bit about how the tunes are finalized? It stems from data logging and data tracing each model under various conditions, from extended cruising to spirited driving, and adjusting every single necessary parameter, including: idle valve duty, injector dead time, fueling, injector latency, ignition timing, air-to-fuel ratio, top speed limited, speed buffer, and many more. I have even taken the time to expand many maps.
A perfect example would be the M20B25 tunes. Stock and most every other tune on the market are not able to provide new values for any ignition, fueling, or anything else above 6200RPM range. However, with the SSSQUID tunes, values ranges extrapolate and are optimized all the way to the very last RPM before red-line (which has been increased to 6800RPM on the M20B25).
This also means that, say you need a custom tune for upgraded valves, springs, and head-work, and you want it to rev to 7200RPM. No problem, and that also means that I will custom edit a file to extrapolate data all the way to the 7200RPM mark.
Here is an example of a comparison between stock and custom tuned SSSQUID ignition timing for a car with upgraded a complete Bimmerheads head package on a 2.7L block, with slightly lower CR.
And then compare the stock target fueling vs SSSquid Tuning for that same application
