North American Model AWD Didn't work

 

Do you have the original oem Race DNA knob of the q or do you convert your original DNA knob?

 

Not having the switch and changing the PROXI config? Nope. I changed the PROXI and I have the OEM switch. No issues. Alignment went fine.

Which OEM switch do you have?
The OEM QV Race Mode Switch or the normal one converted?

Ha, yeah, sorry. Ti DNA not converted yet.

 

I'm getting my elm cable and adapters in a few weeks. Will I be able to access proxi in multiecuscan free version?

 

In germany is this not possibile in free version

 

This topic is getting confusing, I understand. Lots of different plots. Lol

I currently do not have race mode. I have successfully changed the PROXI config though, but I do not yet have a way to trigger the race mode using the selector. I will modify my DNA (non - qv) selector once Dorifto figures it out. More than likely it is only necessary to add a microswitch and resistor to the existing DNA selector in the 2.0t.

Others have purchased the QV RDNA selector.

 

for those who want to know the partnumber of the DNA-Race Knob: 156 129 321
This knob is compatible with all giulias until the MY19 for europe with euro6d temp norm.
As in my former post, i drive a Giulia Veloce Q4 MY18 build in March 2018.
I changed the knob and byte 88. everything works fine.
I updated all ECU´s to the latest version at the alfa dealer bevor.

Hardware:
Dell XPS 15
MES 4.4 Registered
OBD Direct Interface ELM 1.4
Adapters grey and blue.

It doesn´t matter if it is a Q4 a Q2 or a normal RWD...

Attached you will find my STOCK PROXY:

 

So on the 2.0 Q4 in Race mode it deactivates the ESC correct? Is there any other affects such as active torque vectoring and turbochargers? Can someone explain or confirm from experience what are all the benefits for mod to Race Mode on Q4, thank you.

 

Non-QV don't have a torque vectoring differential or the torque vectoring module, so that isn't going to happen.

 

No, they're not magnetorheological.

 

So is the only benefit on a 2.0 Q4 doing this race mode mod is deactivating the ESC correct? No other benefits? Has there been any negative effects after the mod? Just trying to understand what the pro & cons are to doing this mod.

 

Already been discussed what does race mode change.
"
If its anything like QV race mode:
Less assisting electric steering wheel
Faster shifts
Power shifting in manual mode
Snappier brakes
More sensitive gas pedal
Stiffier adaptive suspension
Electronic stability control disable
More overboost
Less torque limitation"

 

So when do we talk about if the hidden race mode is fully baked or was abandoned sometime during development...

 

There are several possible reasons why 2.0T might not have race mode. Inside information is needed to know the actual reason.

 

Have you seen/read this thread. ? Seems like they to nailed it.

Yes!

is described exactly by the same person that described it here.

 

I get ISO not supported for Drive train control node, i'm thinking this is my problem. The next step is how to fix it?

 

But you get ISO not supported for Engine and Radio too?!

 

Euro NCAP crash test rating.

Not allowing to turn off ESC awards them additional safety. On paper.

 

Got a call from the shop, without knowing which resistor is missing, and having diagrams its just too much of the guessing game, and eventually will get more expensive than just buying dna-r switch. So im giving up on the idea of modyfing one, and going with just getting a dna-r switch, and swapping tops so it looks original

 

I'm on my phone and can't easily relay the info, but someone on page 6 gave this info...

Between pin 5 and 6

A- 1,32 kohm
N- 523 ohm
D- 236 ohm
R- 90,8 ohm

 

I just had a brainstorm, still looking into it, but basically this solution wont require modifying your switch!

 

So Today we modified the original DNA knob, installed and switched off with proxy on my uncle his giulia 2.2 jtd at8.

Race Modus works, the only thing he can't switch the gears manually in race mode.

 

Here we go, my prototype bypass works lol, usa market 2.0t rwd, 2017

 

Spill the beans!!

 

Well, i still have to figure out where to place the button so its accesable and not in the view. But basically since we knew the resistance needed to engage race mode, i just made a switch with the required resistance and added it to the pins 5-6

 

How are the pins numbered? I’d like to attach 90 ohms of resistance between 5 and 6 to test (after MES proxi change).

 

 

Smart. Did you have to do the proxy thing as well with MES?

 

Yes changed those 3 bytes,

Anyway shift points dont work even with p2 rev limiter

 

Did you drive too?
Can you shift manually in race mode?

 

Yep drove it, shifts fast, and works perfectly

 

Yes yes you have it on the dash, but that has been possible/known for about a year. But apparently without the byte corrections that make it actually do something.
We need "functioning" vids with enthusiastic "it really works" reports!

 

I got a video where you see the giulia making a donut. But i can‘t put it online

 

Okay, and you change all three bytes.





I just change bytes 88 and I couldn't.

Maybe i have to change the other two bytes too..

 

Everything is baked allright, its funny that you still think i dont have a race mode. Ill make a vid tomorrow on my way to wotk

 

That's not what I said. I have no doubt that you and others have it working. But I think we are all waiting to see some good action...and race mode does not create hyper-sensitive brakes. On the QV they are less sensitive. What are your observations on throttle response? If you hold steady (cruising or slight acceleration) throttle, and cycle between race and dynamic mode, what behavior do you observe?

 

What are the difference for the G meter between Dynamic and Race, other than the obvious Red and Yellow graphics?

 

Ill try to make more extensive video tomorrow, and ill give you more info, im still intrested if the p2 tune works in race mode, i mean car feel really allive from stand still, pushing over 0.7g on acceleration

 

IIRC bone stock RWD 2.0 were hitting 0.8G peak in the 0-60 thread and @chaadster's piggy backed Q4 was something like 1.2G peak. If the P2 tune isn't working in race mode, I think you'd know it. In fact, I doubt there's a built-in ECU map at all for race mode on a 2.0, but the EC guys would know best.

 

Well one thing mine isnt lsd optioned, another thing i didnt do lauch pull, ill try tomorrow
