BTW, Bill, I've been cordial and assertive with the people I've dealt with, only coming close to the boiling point once with BMWNA customer service. The trouble is, even when they TRY to help you, they are not always enabled, and that is as frustrating as anything else. You'd think for a global corporation that relies so much on advanced technology to keep its customers safe, they'd be better at internally educating their employees on these things.

Does anyone know the best way to quantitatively compare the lag in two cars? I think I know someone who still has a pre-29.2 (and no tick) and would like to compare the retrofit with it.

Mine is updated with 2.32.1, and mine rattles at 3300 rpm on neutral decel. Not sure if I got the retrofit since there is no mention of it. I'm assuming I don't. My vehicle data status is E89x-08-03-530.

Meyer, great to hear that you are enjoying the car again!
Mine is at the dealership now getting the hood bend fixed, then it is over to the service dept for a few things(including the new update).
I hope it goes smoothly.

so what ur saying is that we all NEED to get the conversion and not just the software??? otherwise well end up with the dreaded rattle???

my car is going in this weekend and im bringing the SIB so i need to tell the SA what i want.

thanx

If you did not specifically request lag-fix, then you got the [ironically named] rattle-fix. And, like me and at least a few other people here, you hear the wastegate opening at 3300 RPM.

I know you already believe me, but if you want to see for yourself that it's the wastegate, just open the hood and get a friend to rev the engine while you watch the outside wastegate actuator arm, and you will see it open at 3300 RPM. Or, set up a video camera trained on the turbo and do the revving yourself. If I had a tripod, then I'd do this and post it for everyone to see.

To rule out noisy wastegates as the differentiator here, I am wondering if someone who DOESN'T hear the noise could run the above experiment to visually confirm my theory. That would be, if I am not mistaken, anyone with *confirmed* 2.32.1 lag-fix and/or anyone who is pre-29.2.

Lastly, dinkoh, this almost slipped by me... are you sure about E89x-08-03-530 and 2.32.1? IIRC, 08-03-530 is the 29.2-30.x data status, which means that one of those numbers must be incorrect.

I checked the Functional Software Verison under the Applikations menu:

It reads: 008.106.001....does this mean anythign to anybody?

I specifically requested the lag-fix. I did not mention any "turbo or wastegate retrofit". They did mention that my engine would be louder, not sure if it included more wastegate rattle or not.

So are you sure your current version is E89x-08-03-530, or is that your previous/original version? Because if that's your current status, then you do not have 32.1 at all.

Also, I requested "lagfix" and even mentioned "turbo retrofit" and "wastegate" and all that jazz two, three, four times before my initial update, and was reassured they knew what I was talking about. And I was working with arguably the two most knowledgeable dealerships in the state. Yet they still missed the wastegate conversion the first time (and possibly the second time as well, which I'm trying to figure out) because it is not something the tech is prompted for.

The bulletin I posted a few pages back was updated in early Feb to be much more clear about the process, but if the tech does not read the whole thing, they can still miss it.

iScream - with a manual trans it's easy to tell if you have the lag free update. Nothing subtle about it. Do the test where you're in second gear going 2,000 rpm - floor it. If you get linear power - you're set. If you get a huge boost of power toward 2800-3000, you're laggin'.

I was able to replicate the lag in this manner on my automatic as well. I will try this method again tonight on my way home from work.

This is the same dealer I questioned about a month ago on this same issue...sounds like they are still behind the curve.

iScream, I will try your test tonight.

Tschuss --- regarding the quote above, are you saying that the behavior you describe above is for 29.2 (i.e. major lag), or for 2.32.1 without the wastegate retrofit (i.e. better than 29.2, but still with lag)?

Well after me pounding on them they should be well aware of it now. I came in there armed with the Technical service bulletin. I think they were just trying to make sure they got paid for reprogramming the car.

Which behavior? Huh? I have never experienced "2.32.1 without the wastegate retrofit". However, based on what I read on these pages, I conclude for MSD80:

Laggy is progman 29.2 or greater; or ISTA/P 2.32.x without lag fix option applied.
No Lag is progman 29.1 or less; or ISTA/P 2.32.x with lag fix option applied.

I did not notice any difference between pre-29.2 vs. ISTA/P 2.32.1 with lag-fix applied.

@iScream:

This may not be the case. I have confirmed 2.32.1 lag-fix ("WAISTGATE [sic] VALVE" RETROFIT) on my paperwork, and I have that noise at 3250 RPM.

MSD80 + ISTA/P 2.32.1 + lag-fix applied = rattly motor but *much* better performance. (In my case, anyway)

Hi,

The 'wastegate retrofit' is the option via the new ISTA/P programming, that you call "lag fix" --- there is nothing that says: "lag fix" on the machine the tech uses, that's just what we're calling it. Tomato, ToMAto, I think we're saying the same thing there.

From what I've been reading, there was a difference noticed by some people between the following 3 scenarios

A) 29.2 (lag)

B) 2.32.1 withOUT the "lag fix option" (i.e. the wastegate retrofit conversion)

C) 2.32.1 with the "lag fix option" (i.e. the wastegate retrofit conversion)

In other words, I was under the assumption that "B" is BETTER than "A" (i.e. some lag, but less lag than "A"), even though it's still not as good as "C".

And so my question to you regarding the "2nd gear 2k rpms floor it test", was whether or not the whoosh at 2.8k rpm was 29.2 behavior, or 2.32.1 w/out the "lag fix" behavior.

I think the option on the machine is something like "control valve-wastegate" option.

I have not experienced B. From some of the descriptions I've heard, B is no better than A.

To answer your question the "2800 rpm whoosh" was (in my case) 29.2 behavior.

There is nothing subtle about the fix. If you're not sure that you got the lag fixed, you probably don't have it fixed. My wife who rarely drives my car had no problem noticing the difference.

So ultimately we want to get option C?

2.32.1 with the "wastegate retrofit" option

I have to go in next month for 30k check and will ask for this. I have a 03/2007 build and had my fuel pump replaced twice, not sure which version of software I am running anymore...

Cool, thanks for the info.

[iScream]

I'm pretty tuned into the feel of the Lag... In the past 9 months, I've had

A) pre-29.2
B) 29.2
C) 29.2 with new wastegates and new turbos
D) 2.32.1 with no lagfix
E) 2.32.1 (supposedly) with lagfix

I drove option A for by far the most miles, and it was the best, and that is all I am trying to get out of my car. It had no strange wastegate noises, no tick at 3300 RPM, and the original (<200ms) "lag" at all revs higher than 1.4k. Options D and E are indiscernible from one another, but noticeably better than B or C. Some have said D is 90% better than C, but I'd say it's more like 50% better, or only halfway back to A.

Right now I am trying to figure out if this abnormal wastegate behavior is a sign that the lagfix was not applied properly, as I can't tell the difference between D and E, yet some people apparently notice a big difference.

Interesting you do not feel any difference between D and E. Let us know what you come up with.
