Completely different logic.
Different sensor.

Also additional tables for factory boost control map

Doesnt matter.
Its not an actual issue unless you want some sort of mailorder chip like from the 1990's. I assure you that you dont want that.

Once there is any actual tuning option for the Ti-VCT ecu's there will be options to load different fuel and ignition tables regardless of sensors.

Once there's tuning for the Ti-VCT pretty much sky's the limit for optimized bolt on tuning and packages for bolton forced induction kits.

Its a pretty safe bet that some suit at Ford asked Cobb and SCT and Roush and whom ever else not to release any aftermarket tuning until the Focus ST is firmly marketed in north america.
