Terry,
Could you add in a future release of JB4 firmware a setting that permits to close completely (100% DC) the waste gates at idle or lift-off throttle?

To do something comparable as the 1M with the M button engaged.
This could enhance the spool-up time of turbo and reduce lag for cars still affected by this (MSD80)


I monitored the total WG DC% with a led in parallel to the solenoids, at idle or lift-off the DC% is quite low (WG open) in my car on map1 JB4

It won't reduce lag or spool up time, but in some cars will reduce wastegate rattle when letting off the gas. We actually have this in the BETA firmware for testing. Email me if you want to try it.

Any way that the values learned by the map 5 be saved (as a baseline) when switching to another map?
Same thing for map 3.
That way, when switching back to map5/3, it would not have to learn from scratch.
Just asking

Any ideas? It's irritating the 'ish outta me haha...I'm going to go play with it some more maybe i gotta set my car on Menu 5 to 335i metric or whatever, idk...will try. But if anyone else knows anything...Please do tell me. ty

Read Page 1 - you have to move to "4" to disable autoclear.

Why shouldn't it reduce the lag?

In the 1M pressing the M button the WG is closed at idle and low load to spin the turbo and reducing the lag. Why this would not apply to the 335/135?

We already close the wastegates when in motion and pushing the gas in more than 0%. The only thing we don't do normally is close them when letting off the gas.

Terry,

Besides noise and unnecessary strain on the turbo. what are the downsides to keeping the waste gates closed at idle?

Just curious. Personally I wouldnt want that.

Yes I noticed this by monitoring the DC % of the JB4, as soon as the gas is pushed more than 0% the DC gores briefly to 100% to close the WG as quick as possible. But I think anticipating it, by closing them always and opening them only when desired boost is reached (PID) could reduce lag a bit.

This is indeed a good solution to rattle, many think to avoid rattle by opening the WG so far that the flapper don't touch any more the seat, but close it to avoid movement (and rattle) of the flapper is even better!

BMW is doing it on the 1M with M button engaged and maybe on the early 2007 335i program (pre 29.2)

All other boost actuated WG turbos have the WG closed at idle!!! (it needs boost to open)

Except little more wear, and less MPG efficiency there shouldn't be any inconvenience???

Likely minimal downsides. The current test firmware closes them when letting off the gas, but then after ~4 seconds lets them go back to their natural state. Seems to work as the rattle comes up only when letting off the gas.

That would be cool. If Terry wants to look into it I've seen a audio test menu in INPA that basically plays a generic tone to test each speaker.

at 105K miles and 30% of those miles meth/dci/93oct/jb4ish i am starting to hear a little bit of wategate rattle from inside the car. It doesn't help that I have the cowling removed!

The noise that i hear is a faint rattle (like valve tap) at very low rpm's.....if i am in any gear and not taching to high and let off gas pedal i can hear that valve tapping noise for a split second or two....if i give the gas ever so slightly and let off ever so slightly that little tapping noise comes back.....weird. Almost like that pinging sound feel on a car (not bmw) with low octaine gas.

I was at first worried that a valve was loose or something, but the car runds awesome, no codes and recent oil change didn't change noise.

Would need access to that to scan the CAN commands for the tones.

Doesn't it already do that? The only thing we could do would be to show gear on the oil or fuel gauge, etc.

You must be referring to when the car is in normal auto mode, because the wife's car shows up when in manual mode. For me, mine is a MT and I always know what gear I'm in!

Just checking in to see how the aggressive map testing is coming and if there are any plans for a more aggressive meth map in the works.

Thanks for all the hard work T!

Non-meth stuff is coming along nicely. With meth performance is really just a function of octane, meth quality, and your meth additive setting. So although the new firmware will help clean up the fueling end a bit down low performance is going to be more or less be unchanged.

I have to chuckle at the map8. What are you gonna do when a hot chic pulls up to you in her svt focus and wants to put it to you, and she does...be strong...be ready. Be BMW! Need I say more? No one underestimates a BMW... No one! Anyone with me... Hear me?...
