Optimum shift indicator

Im guessing thats how the DCT transmission would be shifting if left in automatic mode

6MT ftw

I sure as hell didn't buy this car to shift at 1200RPM everywhere I go lol. I would be driving a Corolla if that were so.

On the other hand, if there is anybody who has the current gear indicator without the shift indicator and he can share his CAFD files, I can easily isolate the relevant code.

I think my M4 displays only the current gear indicator. i have attached the original CAFD file for HU_NBT. BTW, do you manually parse the srec data or is there a tool to parse and do the diff ? (obviousely esys parses the data ...)

There is a tool by TokenMaster called NcdCafdTool: http://www.bimmerfest.com/forums/sho...d.php?t=724259.

To confirm, you have no shift indicator even when in manual mode?

thanks for the link! I swear i have never seen the shift ind , but now i am not 100% as i look at the HUD most of the time so I will for a quick drive now ok confirmed, i dont have the shift indicator in manual mode in either efficient, S or S+. man i love driving the car at night and in manual mode :-)

Great, thanks. I am going to see if I can find the relevant parameter(s).

do you have a HU_NBT cafd where the car displays the shift indicator ? i can give a hand now that i have the cafd tool. I spoke too fast, the link you provided was for v0.2.1 which doesn't work, i spent the last 20mn looking for v0.3.6
this version of the tool works and decodes the SVT displaying the text instead of "."

I have attached my CAFDs for HU_NBT and KOMBI (the latter is before the flash to v.56.2_PSdZData to make it easier to compare to yours). Actually, it is KOMBI that I would like it see.

thanks, i have updated my post #68 above to include KOMBI CAFD orig.

ok here is the diff, i have highlighted something, do you think thats it ?
Left file is yours, right file is mine

I tried some time ago setting SPA_IST_GANG_ENABLE to "nicht_aktiv" and I lost the indicator for the current gear (as the name of the parameter implies), while the upshift/downshift arrows were still in place. Setting SPA_KOMBISELECT_DISABLE to "nicht_aktiv" disabled the ability to turn the entire SPA on/off using the checkbox in iDrive (see post #53).

However, I tried changing each parameter in isolation. I will try to see if I get anything different changing them both together.

A quick update, I have enabled the three parameters on my DCT equipped F82, and the gear indicator disappeared from the cluster and HUD and didn't have a checkbox in idrive. So I reverted back. Not sure why... FYI, when you code Kombi, the time/date is unset and there's a stupid exclamation mark in the cluster that goes away when the time/date is set.

It looks like KOMBI is receiving the SPA information from different ECUs depending on whether the car has MT or DCT and that the relevant settings are in that ECU.

The pictures in post #1 show the upshift/downshift indicator on a car with DCT, so (since you do not have the indicator) there should be a parameter that controls this indicator in the DCT ECU.

Programming in modern ECU's is getting pretty sophisticated.


F8x shift indicator logic routine:

Vehicle speed < 1mph ? -----No------> Turn engine off

Yes

v
Recommend shifting to 6th gear

We are fortunate that the logic routine is sophisticated enough to at least do this:

Vehicle speed < 1mph ? -----Yes------> Turn engine off

|

No

v

Recommend shifting to 6th gear

is the optimum shift indicator also present in the M HUD ? it just hit me that the top row in my M HUD doesn't display anything ! (even in S mode)

The shift lights in the tachometer are different from the gear shift indicator (SPA). Unless something is not working as it should, you should have them in your HUD, but they only appear as you are getting close to the redline, while the SPA is present most of the time with the 6MT (constantly telling to shift up to 6th).

and that explains it, close to redline is uncharted territory for me, thanks.

It also makes an audible tone... Or I could be hearing things...

Not mine (fortunately)

That's the S55 nearing 7500RPM that you are hearing

Those are the shift light. They warn you when nearing redline and tell you when to shift to maximize acceleration.

The "Optimum Shift Indicator" suggest which gear should be engaged to maximize fuel economy.

Ok I get it, I should have thought about it for a sec... Is there any videos w that in action? I guess most track'ers will see that as they come close to redline on straights? Found few now that I know what it is called. Looks awesome! I guess one day I'll get to see it in person
