EDIT: But still complain to help out everyone!

The exhaust drone is more annoying than the lag. I still have to send my harness to Shiv for some adjustments coz am one of the beta testers ..can't wait till I get it back..

Even a non BMW dealer can put you back to older version.

A dealer (at least in the US) will not reflash you back.

+1 They will likely tell you to go have relations with yourself.

The lag is still there but I need more time to drive and figure out what's going on... Whether I'm just not use to the rev2 or is 29.2 slowing me down????
It definately seems more responsive if I DON"T go WOT for some odd reason. Remember, I'm coming from original stage 1 flashed back in december. I only drove 100 miles at most on stage2rev2 last week. So this throttle Response is still new to me.

I am 6MT with a may'07 build. I am also still waiting on a return call from dan at thompson.

I will say, this is very very interesting, but not very surprising. Kind of what I suspected, and very dissapointing on Dinan's part.
Here is my speculation/conclusion. Take it for the 2 cents it's worth.
Basically, they flash the modules controlling the boost maps and whatnot (I know the car doesn't have "boost maps" but work with me here). BUT, they don't touch the module(s) that control the wastegate duty cycles for emissions purposes. Therefore, we get LAG + SOMWHAT FASTER CAR = 29.2 + Dinan. Dinan probably was being lazy and just acknowledged that peak HP/TQ is the same as pre 29.2, which I don't doubt. Problem is, that peak comes on like a pregnant sloth in molasses rather than NOW like with a pre 29.2 car.

Basically, everything I have read in this thread looks like a mess of unconfirmed hysteria.

Everyone calm down, and take a deep breath.

Canes, are you sure all this isn't in your head? You psyched yourself out big time over this whole 29.2 thing.

Do you even know 100% if you have 29.2?

Until you've driven the car more, or find out what exactly has gone down, everyone needs just needs to relax.

You really don't even know what is actually going on. Judging by what has been stated in this thread, I am quite confident that STILL nobody knows what the hell is going on.

It is very interesting that you would assume the worst though, with your conlusion only being based upon early speculation from one member. I guess you don't mind if you have to eat your words later.

And truthfully, I really don't see the purpose of your post, besides trying to stir up "tuner wars" crap.

Yeah definitely let us know what "Dan at Thompson" says. But you say that the car is pulling better now. Maybe this whole thing is psychological for you? I wouldn't be surprised, as a number of us thought we still had boost when we were accidentally flashed back to stock. Drive the car more, get used to the flash, and try to forget about 29.2 and lag.

Someone just needs to flat out call or visit Dinan and ask them about 29.2 and not leave/stop talking until there is a clear answer.

Or Canes, if possible, try to get a dyno to see if all the power is there. Even though I don't think this is really a "power" issue.

I don't think 29.2 should have an effect on the flash. As far as I'm concerned, with the apparent lack of information you have been provided by your dealer Canes, the questions about 29.2 and Dinan still remain unanswered.

Well, amen to that. Heck of a challenge though.

What would be fantastic for the community would be if someone with the Dianan flash, who lives near their headquarters out there went and got 29.2. Then, if they felt a negative impact, drive over to Dinan and park the car in front of their garage until they deal with it.

That would work too!

I'm just not sure about this whole thing yet until Canes hears more from his dealer, and Canes drives more.

Unfortunately, if this is indeed a problem it will affect all of us eventually. BMW will crowbar-in this update for future repairs. A local in Cali could easily get to the bottom of this.

If it is a problem, then I am sure Dinan will find a way to work around it or fix it. I'm very skeptical of the idea that 29.2 causes issues with the flash though.

+1000 on a Cali member getting down to the bottom of this.

I def know what you mean about being more responsive if you go partial throttle. I feel the same thing you do. However the car has instant throttle response when I though the throttle.

I am assuming Cane and Murph both have the Dinan (stg 2). Cane has 29.2 and Muph does not. Possible for you two to meet up in the Jersey shore area where Cane's heading and do a direct comparo? That would be incredibly telling!

OK GUYS! After 100+ miles of driving yesterday, the POWER IS THERE! I don't know if my car was still adjusting or what, but the "oh shit factor" is back when you get on it! Thompson confirmed that everything is ok with the flash as I suspected.
I'm still holding off judgement until after my weekend trip of driving, but this definately is getting better. I assume I'm getting use to the new throttle points. It still is weird to me how if I go WOT(this is where the lag is!) it doesn't repond as good as if I just go 1/4 or 1/2 throttle. The power is definately distributed differently than original stage1.
Sorry to cause mass panic and send this board into a frenzy. I will update you if I can throughout the weekend if I can find a computer.

Also, thanks to steve at dinan for contacting me after being alerted to my issues!

Well, it is good to see the car/you are adjusting. Did you get an explanation regarding WOT throttle lag? Sounds like this continues to be a problem. I forgot, do you have a AT or MT?

+1! So, having the 29.2 lag + Dinan power is better than 29.2 lag + no real extra power after the Dinan flash. BUT, were we'd WANT Dinan to get us is 29.2 lag REMOVED + Dinan power!

Did you get to talk to Steve about the lag specifically and whether than can possibly work to overwrite those parameters causing those wastegate duty cycles inducing lag?

6 MT- still have gotten no explaination except call BMW and complain(this is what my dealer said to do)!
The car is definately getting stronger. I'm off for the weekend!
peace

[StarrDlux]

i'd like to here from dinan as to their idea as to what's going on. we're making alot of assumptions (AT6 versus MT6) and without datalogging gear which i'm sure dinan has and we don't it is very likely we're just guessing?

Can anyone get Mr dinan himself on the line to test (AT6 and MT6) pre 29.2 and post 29.2 ?

Since the dealer really isn't going to tell you unless you can get him to go for some datalogging on the Down Low this seems most logical.

[stressdoc]

I really wish that we had someone knowledgeable to describe the 'adaptation' algorithm for us. Over and over again we get complaints about how unresponsive etc. cars are after some service or another, but then after a few hundred miles it's back to being the 335 that we all know and love.

Maybe we could get Shiv, scalbert, marvelphx, hotrod2448, et al to help us to understand how the ECU adjusts to driving style.

[M4TW]

Program 29.2 is yesterday's news.

It seems BMW already has a newer version out (version 30. something). I discovered this because I am having my car flashed today with Stage II ver. 2. I was also scheduled to get my CD player replaced which, I confirmed, requires a full software reload. And that would have resulted in the latest software being loaded.

So I axed the CD repair because I can live without my CD player (I have 6FL) until all these software issues are sorted. But I can't live without my Dinan powered badassed ride.

[StarrDlux]

yeah i'd like to know if the ecu has:
1. battery backup
2. flash nvram

for adaptation.

or if you can unplug the battery (capacitor& ram) and make it spring fresh like the ecu's of days gone by.

You know what would be cool is a high res photo of the ecu and all chips so we could see what components exist if they are not all bmw custom asic's.

would be funny if DME80/81 is just bosch motronic with a bmw label on it
