One question for the GSR guys though; why only 50 or so WHP increase on the inital flash? Isn't a flash supposed to unlock significantly more potential than a piggyback tune?

you have to factor in a lot of things. They want the tune to be safe to people to use.

50WHP is still a lot of power from just a tune with no exhaust work.

There were rumours that the F series encryption had been leaked... Maybe GSR have been lucky enough to get hold of it

- Yes, the ECU flash is real, this is not a hoax! No smoke and mirrors, its not a reported Yeti sighting Hehe

- Yes, the ECU flash is done via the OBD2 Port just as the factory would do it.

- Yes, the Max speed limiter is deactivated (See Video Link on previous post)

- Data Logs and Related Information: We will post more information in the coming weeks as we are currently developing tunes for the F10 M5, the GSR 228i Racing Project, the 650 and 740 non M Turbo V8s, and the current Generation 35i engines.

Please be patient as there is a massive amount of work involved in bringing these products to market utilizing proper testing methodology and validation processes. It is our goal to present the community with the best possible products that combine amazing performance with factory reliability.

As you can imagine having an OBD2 Flash available for the current Untunable generation of vehicles is no easy feat. While we are new to this Forum, we are an established and respected company. We have a very talented and experienced team which brings unique technical capabilities to the BMW Marketplace. Check out our New Sponsor Intro Post or give us a call to find out more

Why don't you post the boost logs from your baseline and tuned Dyno's? That data should already be available and easy to show us!

Check out this link to see the GSR M4 hit 162 on a closed coarse road in 5th gear before we run out of road!

Goodbye 155 mph speedlimiter...

BMW are stating the limiter is 155 but a stock M3 hit 165 no problem.

I hit the limiter repeatedly at 268 km/hr (166 mph) indicated on the German autobahn.

What is the price!! I want this bad!

[Slow///1]

Great news on the ecu crack. Hopefully a few tuners will get access and start competing!

Heard that too. I have a feeling GSR won't be the only one releasing a tune.

Hopefully BMW doesn't catch wind and start a "software update" campaign.

very cool!

[svc0x80]

Very cool. I'll take this option over a 16bit PIC microcontroller any day.

Will this be available as a handheld device for individuals to use?

[TurboSid]

Awesome. I met GSR crew at an event in West Palm Beach a couple years back. Nice people who were more than happy to show me around their drift z4.

Will your flash tune be locked to OTS maps done by you only or will the end user be able to tweak them?

We the users would like complete control. Maybe offer two options?

Access port kinda like Cobb? Pretty please

[RingMeister01]

Gawd that was quick

If you're referring to the JB4. Most of their dynos are with a mix of 91 and ethanol.

[ASAP]

GSR Autosport, do you care to show some screencaps of the tables that you modify and list what those tables are? How is fueling scaled in this motor? Also, some logs with boost, timing, fuel trims and AFR would be ideal.

I don't see any of those items as being a secret if you truly have a tune.

Their Stage 1 91OCT was +52whp/+75wtq, for the record.

So your saying there's a chance for us S63tu owners...

Would be great if the encryption was finally cracked or gotten a hold of but I'm still not holding my breath. There has been a lot of false hopes over the past 3 years since the S63tu engine came out so I'm still very skeptical.

They don't have a tune, but I'm sure they can send you the F10 M5 press file to load up!

[JRV]

Maybe another thing to do is find out from Jailbreak Tuning. Their in collaboration with GSR but seems like Jailbreak may have been the brains behind it...just guessing here and not meant to offend GSR.

[M4LAKA]

I was at a autoshow yesterday here in toronto(importfest) and at the Eurocharged booth the guy was here from Houston with his gallardo tt(he does all the tuning for underground racing I believe), and he told me that they already cracked the M4 and M5/M6. The numbers that GSR are claiming are about what he told me he can do for my car. But they told me the ecu is cracked and can be flashed.

Well, they said they were developing it so?

And why do you doubt them? Do you know something we don't?

[svc0x80]

The F10 M5 and M4 use similar ECUs. The Bosch MEVD17.2.x. They use an Infineon TriCore 1797 processor. I assume it was a private key used for signing that was "cracked". ASICs? ftw?
