Incorrect, it was on 91 octane + a can of NOS Race Formula w/MMT effectively giving him 93 octane.

Like I said, I'm not vouching for GSR. I just get agitated with all the "ZOMG IT'S CIA GRADE ENCRYPTION!"

I agree these claims should be met with skepticism, but it's like the Keystone Cops bucket brigade in here right now with everyone dumping on their speculation as to why it's impossible; a lot of which is focused on the fact that (latest gen) BMW ECU encryption hasn't been broken (yet). My main point is that this, in itself, is not proof that GSR hasn't done what they claim. Things aren't normally broken... until they are.

I am, as much as anyone, interested in seeing them provide more information that will make it clear that they have an actual working flash. I hope they'll do that. I also hope that everyone will simmer down with the "ZOMG IT'S UNPOSSIBLE" stuff.

Good luck to the guinea pigs...

[VCP]

My only concern is, did they re write the file or is it simply a flash of a already designed file (BMW for example) using a tool such as ESYS.

[grimlock]

Not saying it's not possible.. but if they could why would they not be working for NASA/CIA/Google instead of trying to extract 50hp more from a 3.0l TT that is already producing 480-490hp?

Knowledge = Horsepower

"Note: This is not a piggy back system (commonly offered in the mark place) it is an ECU flash, actually reprogramming the car’s computer. As such, the car is not fighting itself to make the power and the ECU’s adaptations will only enhance the power gained opposed to degrading over time."


The fact that you state this and are ignorant to piggybacks says it all.
Sounds like Steve Dinan few years ago.

Good catch. My bad.

Good. As they should be.

[ixse]

lol i can see this turn into piggyback fanboys vs ecu flash fanboys thread. and the funnier part is most of these fanboys have no idea what the real pros n cons of the other side.

You think they have time to be sitting on the computer 24/7 answering all of these questions?

I'm sure they will respond when it is convenient for them.

Everyone here is always so damn needy for answers instantly. Chill out.

Oh please. You don't just release info on what would be pretty damn ground breaking and then not have time to do basic things. Obviously questions were going to be asked as soon as someone claimed they cracked it.

Look at what Gintani did with the TT setup. Dropped a little bit of info, disappeared and kept making excuses, only to come back months later with any useful information.

[biglare]

I'm not seeing much information on their website to help the credibility of these claims. About us section is completely empty. They do list their Facebook posts with GSR about the new M3/M4 tune.

As tempting as it may seem, I'm keeping my car completely stock. BMW finally produced an M3 that I wished previous generations should have came in stock form, ie: 400whp/400ft/lb torque. More than enough for a street driven beast. Congrats though on great #s and output. I'm sure there will be many mod-bitten enthusiast who will be waiting in line for this flash!

[Drizz]

I think the OP greatly underestimated the amount of attention his post was going to generate.

With these Coke bottle cap sized turbo inlets, and making 18.5 PSI, can we really expect that much more even if that ECU is cracked? They already spin at 140,000 RPM....well never see an increase in CFM above what we get today, am I wrong?

Because the NSA can brute force a RSA 1024 bit key in a day.

Most ECUs have a bootloader which has the ability to flash (receive a program and write over some flash, and boot to it) over CAN/Serial/FlexRay. The image has to be signed. The bootloader will contain a public key used to verify the signature of the image. In order to sign the image you require a private key. If the key was created by a flawed RNG you chances of finding it are easier. Obviously the exact implementation can be more complex.

A lot of coffee, IDA Pro and a lot of patience of required for reverse engineering...and that's the easy part.

Back in the day, all you had to worry about was CRC checksums for the maps. Update the map, update the checksums and you're good to go.

Hurry up with the work so I can kick some C63 AMG ass.

BMS has spun them to something like 28psi?

vargas has already ordered a set to put bigger wheels in/high flow.

hopefully this flash tune can compete with BMS power/torque wise. waste of flashing ability if not.

you know it would take more energy than the entire universe has to BRUTE FORCE 1024 bit encryption? LOL

And are you aware the coke cap snails can ramp up to 23.4 psi when needed? 😉. Impressive at 4000 meters elevation.

23.4 is written in from factory. Don't underestimate�

I wonder if they take Bitcoin?
