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

gtman said:

Just curious here. On my US car, I haven't experienced this stutter. I've used the Starter 21 with many different quick adjustment combos. No low speed stutter. I don't get the stutter on the TSP tune either. What's the difference in the US versus Euro setup?

with my inexperience I am trying to understand, for that I ask for fuel trims everywhere. yesterday I did the maintenance, the trims have changed, or they have updated something, or they have reset the ecu or it is the accomplice, the 5w40 oil that they put, put also 1 cm higher than the level

There are quite a few differences in ECU strategies between US / EU (and possibly Canadian / Australian / Asian). The most important being US operate in Closed Loop at high load while EU operate in Open Loop. This is why you will mostly hit AF targets on US models without MAF tuning, and you hit 9's with the same setup in EU models (which led @KTuner to release the tuned MAF option).
The tough part for @KTuner is that the number of EU owners is a lot smaller than US ones, and the ones who are engaged to find / work things out, we are even fewer
Still I think that the community has provided important information over time and @KTuner has followed up by improving the product (e.g. with the MAF scale). I think it will be the same for the "stutter" and with more information and feedback, a solution will be provided by JR.

let's get back to datalogging

just ask us what to do and we'll do it

Just understand that programming / reverse engineering all these different ECU's (and relevant pieces of software) that Honda decided to spread throughout the world, is more complex and time consuming than one may think. For that alone, @KTuner deserves our huge respect, for working on every community request (although they have priorities - they have to make a living, right? )

Add to that the absolute fact that KTuner tuned Euro Civics are a very small portion of overall KTuner sales. The fact that JR has done as much as he has is outstanding.

I've always said, and will always support

Hi guys,

leaving the stuttering, how many of you use this maf configuration, "factori maf w/scaled top end calibration"?

I am using setting "custom".

You can switch to that as a starting point then edit from there as needed!

Custom (when you load a fresh basemap) is factory but you can edit it. Also if you select any other maf calibration when you edit it is considered custom (obvioulsy).

From the buyer's point of view we are paying for a product after all. But they could just have left us without support and they did't, they are allways there to improve things, responding emails and giving support.

My tuner has done a custom tune and the maps are loaded to my KTunerFlash V2 .
If I were to installed Ktuner software onto my notebook, how could I extract out the maps so that I could view the tune and possible do some edits?

I'm using "factory maf w/scaled top end calibration" but it also stutters with the others.
This happens with the starter and TSP Stage 1

is there any news for further updates ?

The tuner would need to provide you the tune. Most tuners will lock their tunes anyways to prevent you from modifying most of the parameters.

Hi guys,

this is my new configuration:


and Early spool enabled.

So, the stuttering is almost gone.
I really can't understand what the reason may be.
