I'm aware they are tuned differently.
CMIIW. Shouldn't the Starter Factory calibration work the same as factory tune meaning if there is no issue with factory tune the stock starter factory should also has no issue?
I don't experience partial throttle knock control rise issue with stock Factory calibration and Stage 2 K-Tuner calibration. Stock Starter factory tune will bring my knock control increased up to 80% driving under 1400 RPM. This issue does not occur with Stage 2 and stock factory calibration. The partial throttle knock control rise issue affecting all starter tunes at stock render these starter tunes useless because they are already problematic at stock level.
I cannot do custom tune if the Starter Factory Calibration or any Starter Tune calibrations have issue at stock level. Would you mind sharing unlocked Stage 0 calibration so I can test and using unlocked Stage 0 as base for my custom tune?
