we unlock for other tuning companies as well.
What is the name of this local tuner?

Looking forward to more info

I'll add that this doesn't surprise me at all. Most of us knew that the flash tunes would come sooner than later

I don't know If this is the case here.

That actually sounds logical... what options are there for people to do this themselves? Can anyone offer a hand held flasher to this? I think unless you have facilities worldwide or can do this remotely... you are extremely limited.

A handheld flashing tool for the end user would be ideal but I'd like to think Cobb Tuning owns the IP on that. I'm not a patent attorney but the functionality of the Accessport is proprietary to some extent.

Several companies offer handheld tuning devices that flash via OBD. Like the Bluefin from Superchips:

Nope, no IP... there are tons of handheld flashers. Hell it doesnt even make a difference if they just offer SW that you can use a laptop to reflash with. All you would need is a CAN compliant cable. If people want to tune for fuels, dyno tune and so forth... you will need to offer a full sw suite. If they are brute unlocking stuff or anything of that sort, I doubt the user will ever have customizability.

Well there's that. Thanks for putting that out there.

I know someone close to the truth on this and the way it was explained to me is that the encyption is on multiple levels but once the ECU is unlocked (and this can be done with the right hardware), it's unlocked permanantly for future editing.

Another local tuning shop in toronto who I trust also claims it has been hacked as of this month and they will be able to tune the m4 withing a couple weeks.

Edit. They didn't hack it themselves, but they will have the solution

correct!

Tuning companies worldwide will have access starting the 5th of January.

Sounds like void warranty to me on a 80k car.

Who knows? Only the guys who come when engines go boom. I don't ever wish to meet them.

We know that, but when the car reaches higher levels of Ecu psi, they we able to see that. Don't be deceptive.

Who would have thought the piggyback might have been a better way to go in terms of a warranty after all

[EndBosS]

if you go to the shop with your piggyback, your warranty is voided.
if you go to the shop with your ecu tune, it's invisible. IF they test it and they datalog it, they will notice.
Therefor, we offer a free of charge reset when you have a warranty issue.

Well maybe...

Can you prove definitively that a dealer or bmw can't tell the ecu hasn't had a flash?

Since you have access to the ecu, can you elaborate on if a piggyback is detectable after removal?

On a side note just for curiousity, did you guys find a security vulnerability or what to gain access?

[hellrotm]

If you pop your motor, a simple little ecu reset is going to help you. They dig a lot deeper into the ecu to figure out what caused the failure.

in which case you are f*cked whether you had a piggy or a flash

if they dig into the motor, you can book it that they will deny you

There are flags that can be switched off to disable certain monitoring functions. And a tuner flash is partial map area flash which doesn't show as a complete flash. So it doesn't increment any flash counters. So flashing can be done without any trace. To be totally safe, buy a spare DME and do all the flashing on one & leave the other bone stock. You will need access to coding software & tools to clone your DME.

The only problem with that is the date/time/event info won't match up with any b.s. story.
