Will the 8Y RS3 ever be tuneable?

[DanMPower]

Not sure if this question has been asked before but from what I read, the new Bosch MG1 ECUs in the 8Y cannot be unlocked. Audi is doing what BMW is doing with the new Bosch ECU and locking the bootloader at a processor level so it's pretty much impossible to gain access.

The new BMW M3/M4s do have a walkaround now finally which consists of sending your ECU to Russia to have it hacked and cloned to another ECU, then sent back to you to gain access to flash via OBD, the whole process costs about $5000-6000 not including the tune and if BMW were to send an OTA update it will be bricked. Nobody in the US has come up with a solution yet for those cars after many years even for the B58, what are the chances of someone investing in a similar "Russian hack" process for the 8Y RS3? Doesn't seem likely, so are the 8Y's destined to just intake/exhaust mods? Will piggyback tunes like the JB4 be the only solution besides going full Syvecs standalone?

That would be a huge deal-breaker for me since the draw of the DAZA is in its tunability and power gain potential.

What’s an OTA update? That’s when you bring it into dealer for service, yea? I havent brought my BMW to dealer since 25k miles and plan to never again because of that threat. I know we’re a small minority in the grand scheme but still feel like they’re doin themselves with these updates.

This video claims “tuned” but there’s no detail about tune, perhaps they just meant the exhaust note was tuned via custom exhaust. https://m.youtube.com/watch?v=XM2Gph1pPoU

If 8Y aren’t tuneable and the used car market crashes as predicted, i’d be much happier to pick up a modded 8V on the cheap instead then

[8STTRS]

What’s an OTA update?

OTA = over the air.

It's something that several manufacturers are doing. They can effectively just update your car, whenever or where ever.

[o1turbo30v]

It will probably be like the B9 S4's, 2-3 years for the tuners to figure out how to do it.

[tegxsi]

All the Audi's with MG1 ECU back then were on the same boat. Once OBD flashing was cracked the flood gates opened for all MG1 Audi's.

Just have to wait it out and see...

The 8y not being tunable isn’t going to drive the 8v down

I was wondering why I couldn't really see any tune data for the 8Y online, now I know why. Also is the JB4 really that bad compared to traditional ecu tune? The piggybacks seem to make pretty decent power gains and have less warranty headaches.

[ECNMY R]

We've been in "too good to be true" territory for a long time, and given the disproportionate resources in this arms race, plus the intensifying incentives of OEMs to have total control (not just for emissions reasons, but also rent-seeking with feature locks, etc), there's every reason to believe the party could be ending.

Of course, these things have always been true to varying degrees. But the scale of technological change is making things less and less small-d democratic. Right to Repair is tied up with Right to Tune and the little guy is losing both.

BMW or Audi or anyone don't want you futzing with a computer that is part of an ongoing revenue stream. Adjusting timing tables is one thing, what about turning on the Adaptive Cruise subscription for free? What happens if they hire the Disney lawyers? ECU code is IP. They will hit your little hot rod shop with a fucking nuke.

With piggybacks like JB4 you are raising the boost and relying on the ECU to pull timing to optimize power. It works if you don't over do it. A splash of E85 is what makes JB4 shine.

[lemonvr6]

It makes it shine because you are riding the knock sensors in lieu of a calibration

I'm confident that it's fine... I've tried it and datalogged it plenty on E30 with zero knock. Stock tune will go up to 15-16 degrees ignition advance when it sees good fuel. Maybe higher when it sees lower IAT.

Stock tune on 91 constantly pulling a ton of timing which is more concerning.

Of course I still prefer ECU tune.

I’m guessing unless Audi starts making us sign something at the time of purchase, that this thing is mine to do what I want. Be real hard for them to tell us otherwise. Now the epa is probably a different story. They can crack down on the tuning.

Pretty soon well all get neutered and be totally whipped by all this headquarters intervention. WTF, whatever happened to I bought and paid for this and its mine to do what i want with it ...

The new ecm update had any more intrusive features packed into it?

My mmi data (without a sim in) is constantly and remotely turned on.
The compenser helps more of their entrance thru the gate.
They are legal hackers of your car. Unless...

Edit: yes, processors can be accessed, remotely, even if off. Welcome to the new world.

[TheContrarian]

A big reason I bought my 8V RS3 was the existence of tuning options at the time of purchase. Buying a car without the ability to tune is like buying a car without a future.

There’s nothing for sale. I think it’s obvious people are trying to develop a tune and that’s all this link is saying Unitronic is doing too.

[jh901]

Seems we are in for a long delay. If DS1 isn't close, then I'm not confident. I had thought that perhaps the Russia/Ukraine situation was a barrier. Could be wrong, but aren't the hackers over that way?

hahahahha just like the flex fuel for the 8v?

[tegxsi]

As far as I know, DS has the 2.5T on the bottom of the list so they may take a while.
They won't be the first...most likely the last to market but their custom features are far superior.

Usually their top priority is 4.0T and I'm guessing the 2.9T/3.0T MG1 will follow. They may still get side tracked with their V10 development because it's just pure awesome not having to go standalone for turbos.

Knowledge gained from the 4.0T MG1 will probably trickle down and speed up development other ECU's.

Any issues? Codes? I have my JB4 from my 2020 RS3 ready to go but George from BMS says it needs a software tweak to work on the 8Y US version...

[kornsined]

Nice! Hopefully this can help me sell mine from my 8V.

No issues as of yet.

When I first fitted the JB4 I was finding the car didn’t like the top pressure sensor being unplugged for some reason.

I’ve now come to the conclusion that it’s best to pop the bonnet then wait while the car shuts down, this way doesn’t bring any warning lights on.

Good to know. Did you data log at all? Assuming there is a noticeable difference from stock? How many miles were on your 8Y when you put the JB4 on?

How did you feed the ODB connection thru firewall. Any tips? Looks like my Rs5 jb4 works on the rs3 also with different firmware.

Thanks! Was it easy to get the inside panels off to access the pass thru? Looks like only up to map3 is supported currently.

On my Uk car it’s a visible rubber grommet up on the passenger side closer to the outside ‘side’ of the car if that makes sense.

To the OP. I know you started this topic 5 months ago. I am 5 month late to responding you but I am 100% certain, YES. It make take a few months for the big tuners to release their tunes but there are already piggy backs and power boxes in the market. The engine on the 2023 is virtually identical to the previous years so it is a matter of just cracking the ECM/ECU and copying the files. Cracking the ECM seems to be the challenging part.

Not sure if there is any confirmation that the motor is exactly the same. They do not share the same engine code so it is quite possible there are minor differences.

With piggybacks like JB4 you are raising the boost and relying on the ECU to pull timing to optimize power. It works if you don't over do it. A splash of E85 is what makes JB4 shine.

this, e85 is the saving grace to clean up the logs to zero or near zero corrections.

But the JB4 seems to work fine, I believe I've seen some logs with near zero corrections get to near 18-19* of timing up top. I believe Tony himself ran 10.8@128mph on his TTRS with just a 22psi map, e30 pump/e85 a few years back as well so it's not too far off from those running 93 stage 1 files w/ a splash of e85 as well.

Recently cracked the mk8 golf ecu’s, it’s only a matter of time now!

The challenge is the ECU, the engine being nearly identical doesn’t really help in this scenario. Yes they already have the maps ready to go more or less, but they’re having a hell of a time cracking it. Yes I know it will be cracked, I’m not implying it won’t.

[tegxsi]

MK8 uses Continental Simos 19.8.
I don't think the protection Simos is as difficult as Bosch MG1 that 8Y has

Are those prices correct?

$7000 for stage 1 plus 5-day installation?
$12,000 for stage 2 plus 5-day installation?

If so my guess is they are replacing the entire ECU with a flashable unit just like the BMW guys are doing?
