[Mr. 5]

I'm definitely interested in the GIAC flash because there's so much that they can do that a piggy cannot.
For example, I've heard that the GIAC flash closes the wastegates at idle the same exact way as the pre 29.2 programing, which means that the throttle response will be extremely better than the piggys.
Yes, there are lagfix maps with the piggys but the lag fix maps don't close the wastegates completely, and this is the reason for the wastegate rattle.

Why would anyone stay with a piggy, if the flash does just as well? I can understand how some people have already invested in a "tune" would stay with their current tune but overall a flash controls more parameters, is the easiest install, and is not as detectable, hell once bmw figures a way to store codes a way that not even the bt tool or other devices can remove them piggys are back to square one, and the first poor fool who walks in after that upgrade would have loved waiting 45 minutes for a complete rewrite.

Well, it's a cat-and-mouse game. Anything that BMW does can be undone in one way or another, whether through software or hardware manipulation. It's just a matter of how long it takes, and what resources are consumed fighting it.

Whatever option allows me to have the most control is the one I will take...

You might want to try more reliable sources "discostick".

A friend of mine whose sister dates a guy at BMW told me that the DME's will communicate wireless so what you gonna do then?

Communicate with what. What are they going to do build their own cellular network with the sole purpose of receiving shadow codes from tuned 335is.

Ahhh so this is finally how my first negative post in all my time at E90 would come to be... well, it had to happen sometime:

There have been rumors of this, and lets be honest it makes sense from BMW's perspective. This is something BT is on top of and the BT Cable will be worth its weight in gold with ALL piggyback and flash owners if/when BMW moves forward with it.

As always, the first line of defense for tuner invisibility is not to trigger those hidden codes in the first place. The backup to that is having a company dedicated to unlocking BMW's DME with the tools available to access every part of it. Including overwriting BINs and shadow memory directly. That is just some of what BT brings to the table.

If a piggy it would have to be fully PNP... which means I won't be paying $1200 (too expensive) for say the CP-E Standback.

Between the PROcede and GIAC under those conditions, I think I would honestly get the cheapest one. Both control many parameters and I feel like actually care about safety.

Let me know when you want to try out a "major" tune.

On a serious note though. BMW doesn't want anyone to modify whilst in warranty. There after they prey people mod so they can make their fat margins on the spares.

I had read a article once that said typical manufacturers make less than 50% of the return on a model from the sale and the balance through spares. They had done a calculation of a 740 which if bought in spares was over 20 times the value of the car.

My buddy is the one who drives the Le-Mans Blue 335i in Taiwan. I have been reading the thread and I just have a few questions about this.

1. what are the good parts of piggy back?? for resale issue??

2. why does it take GIAC almost 2years to come out with a flash??

3. How can you be sure that the piggy back doesn't trigger the BMW tuner codes??

4. How long do you thing GIAC have tested there file before releasing? compared to other companies which seems to have a file ready when the car is just on the market?? is it really the best or NOT really tested??

5. GIAC is the top brand for Porsche, VW, Audi, and now working slowing into the BMW market. Will they gain market share?? I don't know.

Here is a link: M3 GIAC vs. Powerchips
Modded M3 GIAC chip vs. 392whp E90 with powerchip with every bolt on

*for me driving an M3 I have been back to the dealers in Taiwan a couple of times after my flash today its back again doing the BMW Performance Steering wheel. No problem , NOTHING just thank you for shopping at BMW.

[SHOTGUN]

anyone that has previous experience with tunning vw, audi, or porche will jump on giac.
for the rest of the 335 owners it will take some time but eventually they will
see this is by far the best option.

Just so it's known,

You cannot remove GIAC from your ECU unless you send it to be reflashed. You can switch the maps with the switcher, but you cannot remove the map.

The idea is not to completely remove the flash, but rather to revert back to a stock file so that when making a dealer trip the flash is not detected.

I don't know whats with all this talk of sending your ECU to be flashed is about.. If you look at the GIAC website there are numerous GIAC locations nationwide.

+1 I also do not think he realizes nobody getting the flash is going to expect to be sending the ECU in or going to their local flash dealer to revert back to stock because when this flash was originally advertised a big part of it was the fact that we would be able to flash back to a "stock" map on our own.

from what giac has told me its actually a stock file so not 100% stock, but if on the stock setting your bmw dealer would have to send the ecu to bmwna to find the flash. if your really worried about some serious warranty work u can go to a giac dealer/ mail your ecu to get flashed back to stock. again this is what i was told... sounds pretty sick to me!! i had no problems with my giac flashed b6 s4 when i went to the dealership with a blown out power steering pump. (snow drifting haha)

I understand that but what I am saying is that a supposed advantage of this flash is the fact that you would be able to flash to a once again "stock like" file for dealer visits.

This is supposed to be one of the advantages of this flash over piggybacks but in actuality if I am going to have to go to a dealer and get it reflashed once to stock and once again to my map selection than I rather stick with a 10 minute piggyback removal.

[Eugene-TAIWAN]

For people who can not make a choice right now. just wait until more people on the market get the GIAC file to better compare. I don't really need to because all of my past cars had GIAC file with no problem what so ever.
