Generally, this requires a combination of both turbo tuning knowledge and access to a dyno.
For BTS vs ATR vs LAMFA, that's up to you, its yet another complex topic
For fueling, its pretty straight forwards, you dont want to run over 80%-85% IDC so you have headroom for ATR/BTS
For timing, keep your KR's in the low single digits
For preventing boost oscillations, tune IMX and DRL carefully, or use feedforward.
I know a couple places that have a dyno.
Right now the current tune is bts, from what I understand about it is that it has more depth to be tuned and is engaged by temp? Compared to lamfa which dosn't offer as much control?
What does idc depend on? How do i keep it down?
For kr where can i find that graph in ecux plot
What parts should I be adjusting in IMX and DRL? The last row? Whats feed forward?
