Am I crazy or is there a difference in the micro switches? Are the activation pins on the outside for some and the inside for other?

 

Dont mind mine, they are broken off, i wasnt carefull when installing it back i broke them

 

Yes is different

 

I wonder if @MacGeek would have schematics for 3 switch part

 

the scheme only changes at the end of 2018

 

Isn't there a part # for the rdna button? Can't be that damn expensive

 

300$ from dealer

 

If this works I'm in for a group buy on the rdna switches... Even though I have awd and can't spin the tires anyway

 

Im down to buy one too!

Aren't there at least 4 different RDNA switches? Are they interchangeable?

1) RDNA with suspension button. Only R is spring loaded.
2) RDNA without suspension button Only R is spring loaded.
3) Mono stable RDNA with suspension button. Europe only?
4) Mono stable RDNA without suspension button. Europe only?

Maybe QV only comes with active suspension so the suspension button is always there? If that is the case will the suspension button cause problems for 2.0T cars that do not have the active suspension?

I expect that cars that have the mono stable switch have different programming of the module that reads the switch and as such are likely not compatible with the older switch style.

 

There is no RDNA without the suspension button, as far as I know.

 

This is correct.

 

Understood, but not the point. Install the wrong switch and there may be malfunctions of the suspension system. I see that Giulia QV appears to have active suspension standard and the RDNA switch only comes on the QV, so your statement is correct. However, if someone installs such a switch in a car that lacks the active suspension what happens if the suspension button is pushed by accident or intention?

 

Suspension button to enable race mode is not needed.

The output line is just one line
The switch only change the resistance

 

What’s the part number for the correct rdna? Would appreciate it if anyone knows

 

After 2018 is not a simple switch !
Is a CAN node ( ECU )
the letters DNA are only visible when the ignition is on ( at least in europe )

 

How do i get to menu where i can change bytes ?

Nvm found it was pressing wrong ctrl and alt lol

 

Ok here is the untouched bytes screen, 2017 giulia ti rwd usa market, guess we have different numeration

 

In byte 88 you have AC So it should works.

Hy Alfisti!

I have a Giulia Veloce Q4 2.0 280PS produced on March 2018. I bought the DNA-Race stud, cost 100€ in Austria, partnumber is: 156 129 321.
I changed the Byte 88 from AC to CC, proxy alignment, recalibrated the ABS Module and now i have the RACE Mode. The transmission in racemode is even faster, the throttle also. ESC is OFF and i am able to do donuts
Only the shift indicator does not work. i think it is because the 2.0 does not rev as high as the Quadrifoglio.

 

Great, So another giulia with race mode [emoji106][emoji41]

Yup i understood it wrong and was looking for 88ac number, now i get it lol

 

@kozak Your switch has adaptive suspension buttons on top? And im going through the pictures looking for needed resistors lol

Yes, in both i got.

Well first ill just try to install 3rd switch and see if it works, if not ill be adding resistors one by one around the switch

 

Between pin 5 and 6

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

 

Yeah, it might be nice to have a PDF instruction for this as I bet this thread will get very long at some point. Reading through might be a pain.

Anyway, I have RDNA switches on order and coming in.

 

Could I order one now and then you just send it out when it arrives?

Ok so byte 157 on my car was 30 do i still change it to 01?

 

neither me nor kozak changed anything but byte 88, we had AC changed to CC.

seems to me that i read in other threafd that in byte 157 there is android auto/carplay related stuff

 

Well i changed all 3 bytes will see how it works once i get my switch sorted out

 

Anyone done this on their 2.0T with adaptive suspension? Do you need to change any additional bytes for the adaptive suspension? And in Race mode, will we now get to have 3 settings just like the QV (soft, medium, hard). The stock 2.0T suspension can only do soft and hard in D mode.

 

I’m sure I’ve missed it, but other than having a 4th position on the DNA knob, what exactly does Race mode do on the 2.0 car?

 

Turns off all of the nannies. So ESC/ASR...(EDIT)

 

While I was messing with the car today, oil change, flip byte 88, proxi alignment general fu$&ery, I checked my DNA selector. It's of the two micro switch flavor, fyi, fwiw.

 

Guys, there are only 3 screens on display or possible made 4 screens?

 

When race mode is activated on screen you will See on yellow race mode
