Go check if your solenoids are leaking. Don't ask me how I don't know, but the dealer replaced mine for same leaking problem I didn't even know I had, but they found it.

I have a Qaife, 6AT and wondering how this interacts with that? A list of scenarios, what to expect and what is really happening would be wonderful. Time allowing ofcourse as I don't thing this is high priority feature, but just rather nice to have.

Bump? Shiv chime in please....

Quick question on this new fw/map.
Upraded turbo maps are for asr & RB turbos only correct? Or us AWD, EPL, ect. Should use the upgraded turbo maps as well??

This process has been described many times. Here's a short:
It doesn't interact with the LSD, how could it? The LSD basically would just give more traction to the rear wheels, so the wheels would over spin less meaning that this type of traction control would kick in less. If your wheels over spin it will pull power (timing/boost) to stop them from over spinning period. The control level essentially determines how much power to pull to stop the spin. The lower the number the more power it's pulling. The higher the number the more power going to the wheels allowing for more and more spinning of the tires. DTC off/on doesn't matter. There is no situation that you would "need" to turn this feature off, except to allow for maximum wheelspin all the time.

As of recently the "upgraded turbo maps" are for full upgraded turbos only (asr, rb, td stage 2). Us guys with "stage 1" turbo upgrades should be using the normal map

Is the default boost control gain on these maps still 45% or did Shiv put it back to 50%? I thought he might have put it back to 50% based on his comment below, but I am seeing 45% and am wondering if I somehow F'd up the firmware or map uploads...

Default is still 45%. I upped it a bit.

If you have the computer plugged in and are reading values, just reload things. It will take you a lot less time to do that than it will for someone to get their computer and plug in to check the value for you.

Furthermore, Shiv prolly has so many things going on that he probably can't remember the default value for this release, unless its something that was on his target. That means he has to stop, change gears, then plug in his computer and read values for you (if he even has this firmware on one of his cars right now).

I don't know about you, but I want Shiv working on more important things rather than spending his time re-explaining things for the 100th time or looking up values for people.

I hope i don't come across like an asshole, cause its not my intent...

+1....i set it to 50

[Jeff@TopGearSolutions]

Default 45... I like it at 50 though.

I tried reloading the map and even the firmware, but after the first load, for some reason, it wouldn't say "loading map" anymore no matter how many times I tried, hence my post asking what the default is (from anyone who happened to be checking).

Shiv would know that off the top of his head if he'd decided to post I'm sure. Give him more credit.

He'd said before releasing this that he was going to adjust boost related things, so I didn't know if this was done too.

Intent notwithstanding, you do come across as one, but no worries, there are plenty of others who decided to be helpful instead.

Thanks Jeff (and others). When I changed it briefly to 50, I thought I saw that the AFR's would swing quite a bit to the lean side when going from cruise to partial throttle, so I put it back, but it was late and needed some more testing. Good to know others have put it at 50 without issues. I'll try that later.

what sort of AFR were you seeing? Remember since we have a DI engine they run a lot more lean during partial throttle and can do that safely.

[vase330]

What does this Boost Control value have to do with AFRs? I don't see the relationship? Jeff can you explain why if at all the setting would affect AFRs? Thanks.

[dzenno]

boost control regulates how quickly boost will spool up to the target...if you're hitting boost too fast and not keeping up with AFR targets properly you could be running into a serious no-no...your fuel mapping/targetting needs to be able to keep up with boost rise so to not cause lean spikes

It would swing like a pendulum back and forth quickly to like 17 or so.

Did you try to duplicate it again?

How did AFR look under WOT?

Not sure what you mean by again. It happened a few times in a row last night after having changed to 50%, so I switched back to 45%.

I don't think under WOT it was an issue.

[dzenno]

Its at part throttle and its more pronounced on earlier maps/firmware...you'll need to load up the latest/greatest and leave that 45% alone...wg compensation will dial in the right number there..

By again, I meant you tried more then once to see if it "adapted". I dont like using the word adapt but its the only word I can think of here.

As you know this car function on closed loop fuel so sometimes on the first onset of partial boost it needs to learn and usually the 2nd time around its closer to safe AFR.

If you have any concern send it in to Vishnu. I just talked to Robert no more then 30 minutes ago on the phone.

I commend you for being concerned with your car and how its performing. Most people load a map and forget everything else about a tuning theory and management.

If you see a problem leave it at 45.

[possible335i2008]

Off topic but should we just wait to get the new stuff on the 11th or download these maps?

[Shellacked135i]

Only takes a minute, why not try the new ones?
