KTuner Update: Map Switching Added To Many More ECUs, Non-Si Adv VSA, more to come

The starter map starts out with no adjustments, so it's not an issue with that base. If you do not like something one of the adjustments is doing, back it off or don't use it. That's why you have control of the starters.

This is my configuration:

Ktuner, do you have an idea about which modify coulds cause the problem?

Thanks

If you're talking about it being throttle related alter the throttle response option.

Do you have "revhang disable" enabled?

Im putting everything together. Here is a little spoiler: https://i.gyazo.com/34ba8aefc252021499027cd9a243c47d.mp4

Here is the video

Attached is the datalog. @KTuner should I send you by mail?

No.
Today or tomorrow i will try this configuration:

Yes, that's exactly what I was talking about. What table are we missing that could affect that?

It's something throttle related, in the video you can see TPS (pedal) is stable at 11-12% but TPS CMD (what the ecu sends) fluctuate a lot. Maybe is the ECU trying to avoid too much throttle or something weird with the pedal response adjustment, I don't know but the goal here is to know the source of the issue and avoid it or fix it.

This also happens with factory throttle responsiveness, and 8-10% TPS will cause TPS.CMD to fluctuate (as will MAP). I found that removing 1-1.5psi from 1500-2000rpm softens this issue by quite a lot.

Hi guys,
tonight i tried the configuration in image.

It seems that the problem has diminished, but unfortunately i feel a little bit of performance drop.

Factory throttle response does not lessen wide open throttle performance, since wide open throttle is wide open throttle regardless.

But the Turbo Spool setting, yes. It's right?

What J.R. is telling you is at WOT what determines your power is boost, fueling, timing advance and little else. What you are changing is the response and how fast you get the boost so you can feel it slower at or under ~3000 rpm but once boost reach the target it does not matter.

@KTuner what can we do about the stutter?
