Daniel, after flashing the latest file and pulling the 64kb flash from it TunerPro shows weird values under Launch Control, when using the LC XDF.

255 for LC Configuration
8160 for Max RPM
etc.

Do you know why that is?

Yes, in the case of THAT particular file those values are no longer important. Just leave the file as it is, flash it onto DME, take the engine for a short ride and test if RPM is limited at ~3000rpm when clutch is pressed and that the normal rpm limiter for neutral gear is working when clutch pedal is not pressed.

I simply changed the code to switch between manual gearbox rpm limiter and auto gearbox rpm limiter, Itīll behave like a LC and its tuneable like to other version.

I just need to change the xdf for that particular software to remove that glitch and make it easy to tune. Unfortunally i can only do so if this tweak does the job for all of you, so its crucial that i get feedback...

No feedback, no progress

Works as advertised now. New file holds rpm at 3k even smoother, almost no bounce, only when clutch is depressed. I will keep testing but it seems to be working.

Please keep it testing for actual launch control behaviour

You can raise c_vs_min_gear_1 if the launch control goes out to early

Did more driving. It's holding the RPM at 3k for as long as I keep the pedal floored. I will keep testing.

I edited the first post and added a modified version of the 64kb fxdf so you guys with LC problems can tune it almost like the "real" LC.

No, without a clutch switch it wonīt work.

If you have a solution in mind, let me know.

Hi there,,

LC isn't working on my 330 as it supposed to do (clutch switch is working fine)

1. what exact file did you flash -- MS430056_M54B30_Logger_EWSsignature_CHK5off_LC.bin
2. what exact xdf are you using -- XDF_MS430056_64kb_Eng_Level_Launch.rar.xdf
3. did you modify anything on the tune before or after flashing -- Exhaust Popping, the vanos tweak, different throttle map, LC rpm to 2464,LC_Vmax to 8kmh, PVSmin to 52°
4. what engine are you running -- m54b30
5. what gearbox does the car have -- 6Speed manual
6. what diff are you using -- stock
7. whats the behaviour of the launch control passing launch rpm -- bouncing once at 3k once, then to redline*
8. upload your latest full flash file where LC does not work and drop me a PM with the link - pn box full :p

*lc works when i'm in neutral, when i put in first gear it does as described above

Could it be, that it has something to do with temperature? it currently -11°C outside and my interior heating is not working (heater valve died 2 days ago) :/

Its a common problem that 6speed manuals tend to donīt like the implementation of LC. Why is that? I have no idea, honestly.

Could it be, that it has something to do with the gear setting? There are always gear 0-5 in the xdf and in the a2l. How do the dme know if i'm currently in the 6th gear if G0 is neutral and what tables it is using?

What is if we enable LC for G0-5 and remove one gear by another to try if we get the right one...


>>just an idea, don't know if it makes sense

I don't have the option for adjusting hysteresis on mine. It has the "on/off" switch. What is that even supposed to be? What is it supposed to be set to?

Probably asking because most people in this thread have problems with the M54B25.

Next iteration should remove all problems.
