Hand Held tuners are not meant to modify custom tunes and I would highly recommend against trying it.

Besides that you have very limited options, Fans setting, speed limiter rev limiter and Idle speed, maybe skip shift.

All of which are typically accounted for in a custom tune.

If you need something changed contact your original tuner.
