… what tables are editable in your software… Please give me a call and I’ll be happy to go over specific tuning questions, but those questions are beyond the scope of this thread… same offer holds for any members or shops interested in specific tuning questions.

For shops, remember this software is applicable to basically any vehicle that comes into the shop, not just the FR-S. Same module, same software, gas or diesel, NA or FI, etc…

For anybody just noodling around questions, it’s important to understand the concept of editing tables has no meaning in a piggyback system… it’s critical for a reflash program but irrelevant for a piggyback. Piggyback’s don’t access the OE ECU and don’t edit tables in the ECU… it’s not how they work.

It’s like asking (in a “reverse vein”) can a reflash digitally change the OE crank sensor signal into an editable form, add or subtract precise values to it, convert the signal back to the wave form the OE ECU expects to see, and then send the OE ECU a signal it doesn't realize has been altered? That’s a critical capability for a piggyback, but for a reflash it’s a meaningless question.

Piggybacks alter signals – if you want to think of it as tables, with the Unichip, you’re adding an editable table to whatever signal you’ve tied into. You tie into the input signal the OE ECU uses to make control decisions on whatever it is you want to change. All of the editing, however, happens in the Unichip not in the OE ECU.
