That appears to be a throttle oscillation.

Load a KTuner starter map and apply the throttle response changes and see if the problem exists there as well.
As they just said, yes, It also happens with the starter maps with the default and changed throttle responses. Do you need any further info or logs about this?
Do you think it could be fixed?

For all those European ECU users that may think they are running rich (Open Loop at Wot) check if your wideband gas type setting on ktuner is 14.7 and not 14 when dataloging (mine was 14 by default). I've been checking with help from Drob and the maf scale is pretty acurate, and AFR are close to target on the richer side. Thank you @D-RobIMW for your help and patience.

There's a simple fix. Buy another one from TSP and get a TSP Stage 1 tune thrown in free. No sense being filled with regret, right?

[QUOTE = "kytos, post: 725410, membro: 19360"] Per tutti quegli utenti di ECU europei che potrebbero pensare di essere ricchi (Open Loop at Wot) controlla se l'impostazione del tipo di gas a banda larga su ktuner è 14.7 e non 14 quando registra dati (il mio era 14 per impostazione predefinita). Ho controllato con l'aiuto di Drob e la scala maf è piuttosto accurata e AFR è vicino al bersaglio sul lato più ricco. Grazie [USER = 15327] @ D-RobIMW [/ USER] per il tuo aiuto e pazienza.

So is that the fix for the throttle ossicilation?

No.. This isn't a fix. This is the proper way to setup datalogs when watching AFR, a few people here are concerend about running too rich and they should know how to check it properly to avoid confusions.

The Air Fuel Ratio thing has nothing to do with the throttle oscillation problem, which is related to the throttle logic on ktuner.

If it may be of any help. When using any of the starter maps in KTuner, the boost target for the 1500-2000rpm range is different than the one when you choose factory boost targets. I have found that copying the factory boost target of that range greatly improves the low throttle stutter.
From what I can understand (but I could be wrong) the TPS.CMD is a function of TPS vs Boost Target (or even better, ECU : where do you want the MAP reading to be?), and it seems that requesting just a bit more MAP (as a function of the % of boost target) causes the ECU to open and close the throttle.
Feel free to reproduce and let me know how this worked

PS : this is completely independent of the throttle response settings

I've been toying around with the idea of opening the MAF curves on all TSP locked files so users can adjust on their own, BTW.
Any update on this?
