Software opinions

In V3 by default you can start with the brake switch or when the gear lever is in P or N position.

Yes, by default is -100%, it is not a big issue:-)

Margins of boost target -60 +60, problem occurs only when playing with pedal gas, especially in corners, rpm are somewhere 3000-4000, turbocharger is “very ready” to go instantly if floored rapidly. Above 4000rpm no problem, as there WG’s DC are higher and engine consumes more air easily:-)

So you suggest to add option to use DC from table when not in margin instead of 100% ?

Please try the kD coefficient in PID controller, it should help. It can require some boost signal filtering (if noisy) but it should prevent boost for overshooting.

There is a bug in DBW strategy. When the Characteristic switch type is set to none, the dbw blend percent is 100% instead of 0%. So the DBW reads characteristic from characteristic table 2.
So you can live with that for the next upgrade, or assign unused switch to DBW characteristic switch. Then dbw blend % will be 0, as expected, and characteristic table 1 will be used

Same issue that I had. It’s set to ignition by default on the default map and thus causes an issue.

Such an option with choosing high or low base DC would be nice:-)

With PIDs on, no better; so trying to perfect the base maps of boost:-)

Thinking about Acceleration enrichment with DBW: is it possible to add option to disable this function at Idle state? Because when setting Acc. TPS threshold low to get best reaction, it occasionally adds some Inj PW when PID is acting.

Yes, DSG input shaft speed would be great. We can do the slip calculations ourselves with the “functions”. I do not understand what is the problem with the service request? In my opinion if ECU Master wants the best solution for DSG there is no other way (clutch pressure K1,K2, slipping…).

It would also be nice to have a separate upshift and downshift table. So that it is not necessary to use both of them. For example upshift only. At the moment this feature is not in V3. I used it for a while in V2 but there you must both tables

I’m not a developer but I’m assuming its a whole different protocol stack that the Devs would have to figure out how to get into the ECU. If that data isn’t on CAN by default, getting it into the ECU some other way will be the issue.

I know I can log that data with OBDEleven and export to a CSV file, but not sure how I would make the data in the CSV file line up with a comparable EMU log.

We will check how complicated is reading via serivce protocol and if it is possible to implement it in EMU BLACK.

I think it is possible to deactive acc enrichment if idle is in active state

How i can use multiple X- axis?

If you select Alpha-N fuel model then the DSG torque table will follow TPS on X axis as the VE and Ignition do.
In Speed Density the load is defined by MAP

little idea for idle strategy improvement in following situation, where i have struggles with:
U are in gear and vehicle rolling; idle active but higher than target → rpm is more or less fixed by vehicle speed
This leads to that the I term of the idle PID runs into its neagtive limit.
If u then press clutch, rpm drops quite deep cause of the high negative integral portion.
I had a lot of problems with this situation and i just could fix it by setting negative integral lim close to 0 (which i dont like in other situations).

I think in general idle controller needs a different setting depending on if vehicle is rolling in gear (stronger air PID; no ignition control) or not in gear (weak air PID strong ignition PID).
So probably a second set of idle controller could make sense, beeing active when vehicle is rolling in gear.
Rolling in gear could be determined by checking rpm/vehiclespeed ratio and clutch= not pressed.

Idea: It would be very helpful to have a search bar for the different Options and Windows and Help windows. Sometimes i try to find an option where i know the name of, but i can’t remember where to find it.

And 2nd:

Would be cool if it was possible to change the order of the Tabs. If i want to change the order I have to rename the tab and open all the respective windows and so on.

We would like to modify the main tree view to add there a search box as in PRO, however it will be done in the future as it is a big change in software and now we focus on the firmware mainly.

According tabs it wouldn’t be a problem.

I understand your issue. We will propose modification to the idle strategy.

Yes, we are missing vss idle increase:-)!

I’d like to suggest an option to reduce axis for the fueling charge temperature correction table from 3D MAP and RPM, to a 2D table vs air flow (g/s) only.

I’m also unable to append/stitch logs together from my EDL-1 on 3.025. I can only append logs recorded with the PC plugged in saved.

Was playing around today with the new idle strategies and it is really great. The tunable ignition control leads to a mega strong idle situation in my setup even just with a little tuning. Really great job. Plz dont change much here.
But one downside:
If i turn of Ignition PID by setting all gains to 0, it leads to that air PID also doesn’t work.
Here my general settings + a log:
