Throttle closures - log linked

[Potato]

Hey guys,

E61 N54, MHD stage 1, 91 octane. I keep getting throttle closures under full throttle. I can't get a good log because the closures but here is a short one:

http://datazap.me/u/potato/e61-n54?log=0&data=3-5-10-23-26-30&zoom=16-42

Any ideas?

Newer plugs, carbon cleaning, vacuum lines, injectors, coils. I do get a 30FF on occasion. I have pretty noticeable wastegate rattle. I turned off the MHD wastegate rattle fix and it did not seem to help the throttle closures.

Throttle closures are you losing traction.. If your logging in third try a 4th gear log

 

[Bmwfixerguy1]

Sorry to explain better throttle closures are a means of traction Control via power reduction

Does that apply to an AWD car?

 

[Derek@MoorePerformance]

^ This is what is happening with that to explain better.

All of the load values are dropping due to the nannies. If it's not traction related then I would attempt to reset the throttle adaptation try another gear and see if it happens again.

I'll attach a picture but, at time @306.85 you can see all of this taking place.

Does that even apply to an AWD car?

I have a 335xi and if I do not cut all the nannies off... no matter what they WILL interfere with data.

Thank you I was gonna post a log of me breaking loose at the top of third and it "ruining" a log

The log wouldn't be completely useless because atleast you can see what all behavior occurred before the event but, there's no direct way to instantly blame nannies unless they're off.

Agreed.. I always have dtc on.. Can't even drive the car with it off lol

Is it possible I am hitting a torque limit? I reset the throttle adaptations. I did another run and got throttle closure as well as DSC/AWD errors. DME Shadow code 2DC5: Torque request via CAN, plausibility.

The question do you have dsc off?
Was this in 4th gear?

What were trying to figure out is if it's wheel slippage causing it

 

[Derek@MoorePerformance]

The log states 2nd gear. The best way to handle it would be to get in 3rd/4th find a long straight stretch, avoid numbered roads (private preferred) Run it from 2500 - 6500 (red line if you want) then we can use those logs. that 2nd gear log shows the closure only after letting off throttle. so, it looks okay tbh

I'm not letting off the throttle. It is being closed by the car. It is quite sudden.

 

[Bmwfixerguy1]

Not trying to be a jerk but you havnt posted a log in a higher gear with dsc off yet.. You need to be in 3rd or 4th

We said that first thing and you havnt replied back saying, ok tried it In 3rd and 4th with dsc off and it's still doing it lol

Are you pushing the DTC button?

 

[Derek@MoorePerformance]

Are you pushing the DTC button?

Doesn't appear like it, but to be certain next time press and hold the DTC button untill everything is off (yellow triangle will pop up)

Find a straight stretch and floor it in 3rd. Don't worry you got AWD. Cutting everything off wont make you spin out or anything. But, it will give us as accurate of a log to overview to help see what's going on.

these cars will try to break loose in second on stock tuning, trying to do a log in 2nd gear with any type of mods or tune just makes no sense. Always log in 3rd or 4th with traction control completely off.

DSC off, 3rd gear, stock boost map. Still having a sudden throttle closure.

Getting this error:

Only code is DME Shadow code 2DC5: Torque request via CAN, plausibility.

Crap video of what the rpm bounce looks like (1st gear but it does the same thing in other gears)
