Where do you see the new version? 1.0.9.4 is only coming up for me.

*edit nm found it on the beta site.
From downloads page (not beta), should show 1.0.9.5 or more once installed.

So is this a manual transmission/Euro ecu issue only? I haven't had this to any noticeable degree on my KTuner or TSP tunes with my non-Si CVT turbo.
Not only for Euro ECUs but im not sure about CVT, maybe is less noticeable because is not a fixed gear.

I've been using a 1.0.9.5 tune since yesterday using the same starter 21 with the most aggressive quick adjustments (just like before with 1.0.9.3), and the hesitation issue on my CVT has almost completely gone away. There were two or three times where there was a little stutter/jumpiness, but nowhere near as bad as before. It makes the drive much more enjoyable now. Great job, @KTuner !

I updated mine to 1.0.9.5 and re-uploaded my TSP Stage 1 CVT tune. I have to say that I immediately noticed a difference. At first, I thought it was just a placebo effect. I'm glad to see others are experiencing the same.

Thanks @KTuner!

So help me out here. The TSP tune includes this new KTuner fix?

Honestly, I'm not sure how this works. However, I do notice a clear difference since I re-uploaded and flashed the TSP tune.

Have you tried it yet?

The fix affects all tunes that are uploaded from the new version, it's lower level stuff.

I wrote in the tsp discussion, but no one replied, say that by reloading the tsp1 file, the change also affects that map?

Load the file from the new ktuner version and reflash the ECU.

The change is applied to all tunes when opened.
OK. Got it.
We are re-introducing some limitations placed by the factory. We will not be introducing any limitations beyond that of factory.
Can you elaborate on what that actually means in layman terms?:dunno:

No I haven't. I guess I'm confused here. I'm happy with my TSP as is. I mean there is the occasional (rare) low speed hesitation but it was there stock too so I just chalked it up to the occasional cvt lag we get.

Ktuner removed some restrictions built in the factory software. This specific restriction is now in place again and set like it was in the factory software (or almost IDK) but won't be set further than stock.

My guess: there is a restriction of how fast or far can the throttle be applied in an specific amount of time but this is pure speculation so don't take my words.

I feel the same. I did however reflash just due to this thread, I feel like it made a bit of a difference but it could really be in my head and I probably haven't driven enough yet.
