Does anyone have access to the cruise/non-cruise status when logging? I see they mention it in the HolyCrapItsFast tuning guide but I've never seen any discussions related to defining that parameter
So many tables are split in to cruise/non-cruise on the 32 bit ecu is everyone just applying their corrections to both equally at all times?
Edit below- I must have glanced over the "TD_D" part ten times, does this refer to Test-driven development? is anyone familiar with that concept or seen any discussion applying it to logging? I guess this implies this is not as simple as finding an address and making a definition.
" Tip: TD_D, This is experimental, but the logic is sound. In opensource, you can now log the cruise / non cruise parameter (0 or 1). You can use this to further refine the cruise vs. non cruise tables accurately. " -George’s (AKA HolyCrapItsFast) Guide to Street Tuning. Subaru STi, GD, (GR) Rev 1.8, 02/17/2016

FYI, I've just been looking at this in my 2010 JDM STI, and there is a parameter that moves between 0 and 1 (0 closed , 1 open), and it pro-rate the cruise vs non-cruise table values based on that parameter (so when its changing state it could be like 0.68 for example), so will use 68% of the non-cruise value and 32% of the cruise table, which is quite nice, it transitions between the two rather than a hard cut over.
I imagine this (RAM) address will be completely different by Rom, mine is FFFF87CC (single precision float type) for Rom AZ1G800S
