This will hopefully be an all encompassing topic on the different ways to enable race mode on the Base / Ti / Veloce / Lusso versions of the 2017-2019 Giulia in North America. These procedures may or may not work in other regions... FYI YMMV

The process can be completed by choosing one of a couple different options, your choice, choose your own adventure:

Mandatory Step 1/2 (read completely first):
  1. You will need a Multiecuscan (MES) license.
    1. Install on a Windows 10 laptop. (Refer to the MES site for configuration assistance.)
  2. Purchase an ODB2 USB adapter.
    1. The MES site has recommendations.
    2. I use the OBDLink SX and it works great.
  3. Find some of the Fiat / Alfa / Lancia OBD2 adapter cables.
    1. As stated on he MES site, you will need the blue and gray cables (#5 and #6 respectively) in order to access the necessary vehicle modules through the OBD2 port. (Note: All module access is through the OBD2 port)
    2. I purchased this set on eBay, shipping took a little bit as I am in the States.
  4. For 2018 + Giulia's (manufacture date roughly after February 2018) it is very likely that you have a device in your car called a Software Gateway Module (SGW / SGM).
    1. I purchased one from EuroCompulsion.
    2. To determine whether or not you have a SGW in your vehicle, use MES and your OBD2 USB adapter to toggle a parameter, like the horn. If you can toggle the horn, you do not have a SGW in your car, you may proceed to one of the next Options (1 or 2).
    3. If you received an error trying to toggle a parameter, please read:
    4. The SGW device prevents writing to the ECM and other vehicle modules. You MUST install a bypass to get around it or just stop now, continuing is useless.
    5. Modify or pay someone to modify the SGW bypass to allow access to all of the vehicles modules. If you don't modify the SGW bypass, you will be unable to complete this process as you are required to perform a PROXI alignment and calibrations.
    6. Installation of the SGW bypass is described in other topics and on the EuroCompulsion site.
Now for options!

Option 1: (I have a bit of money and no time to waste, or I have a bit of money and no soldering skills option.)
  1. Purchase and install the RDNA selector for a Quadrifoglio. Where? Dealership or other. Figure it out, you're smart.
    1. Remove the center console pieces.
      1. Remove the shifter trim piece by prying up on the front of it with your fingers, it pulls straight up with a little bit of force.
      2. Next start at the front by the cup holders for the larger front center console piece. Pull back while lifting up and it should pop.
      3. The piece that the center storage is surrounded by is the same, pull in and up on the sides of it though. You'll get it. Just don't twist or force (bend) any of them, only pull and work fairly straight and upwards.
    2. Once the trim is loose, it's pretty simple, it only requires some torx bits to remove and replace the switch. Don't drop a screw, ask me why.
    3. Re-install the trim pieces in reverse order. Remember that the two main center console pieces fit together prior to reconnecting them to the center console base.
Option 2: (Modify your existing DNA selector. You need to be fairly adept at soldering and working with surface mount devices.)
  1. Procure the resistor and switch defined below. I purchased 10 of each, destroying 4 of the switches in the process of discovering how this all works out though :p.
  2. Disassemble the DNA selector...
    1. This is a tough one to describe as I cannot take photos while I am disassembling... sorry.
    2. Here are the pieces when it's apart...
      1. While pinching the plastic piece with the needle-nose pliers, pull up (Orange arrow) while also pushing out on the tabs (yellow arrows).
        90482
      2. Next, you will see a white plastic piece in there (pictured below, sorry no action shots). On the top and bottom of it, the black plastic is keeping the white plastic from coming out the bottom (in reference to the above photo). Use a small flat head (standard) screwdriver to pry out the black tabs so the white plastic can come out the bottom along with the rest of the selector. You will need to pull pretty good to overcome the 4 extra retention tabs around the circumference of the dial (see below photo, right hand part).
        90483
      3. If you got this far, the rest is pretty easy. BE CAREFUL not to break any tabs.
  3. Install the resistor first in the spot defined in this photo (large arrow).

  4. Second, you will need to remove the pin (small arrow) on the switch prior to installing it. The arrow is pointing to the pin that needs removal.
    1. Bend the metal contact off of the micro-switch using tweezers, make sure any left over nub will not make contact with the circuit board pad. Ideally, this switch should be a DPST-NO (Double Pole - Single Throw - Normally Open) It will work though with this modification.
  5. Install the switch on the circuit board. The guide pins will fit into the holes in the board to assist with alignment. Tweezers help with holding it down. It's a delicate switch, so don't overheat it.
  6. Re-assemble your new RDNA selector and install.
You may have warning lights when you turn on the car, go ahead and clear those out using MES (see MES site, figure it out)

Mandatory Step 2/2: (Configure ECM!! BCM? ABS?)
  1. Configure the ECM to allow the RDNA selector to toggle Race mode
  2. Open MES and connect to the <insert module name here>
    1. Enter PROXI setup
      1. Ctrl+C
      2. Find byte 88 (count bytes starting at one)
      3. Replace AC with CC or EC in byte 88 (see info below)
      4. Do things.
    2. After the PROXI alignment, you will need to connect to the ABS module using the gray (#6) cable. Perform the 3 calibrations below:
    3. PICTURE HERE for calibrations.
  3. Getting tired, hopefully I can post this and finish tomorrow when more sleep has been had.

Sorry guys, I've been working on a migration since yesterday, been a lot of combing log files and scripts. I won't have time to finish the write-up just yet.

Great Job ! Thank you for doing it.

I spent a lot of time in different forums trying to understand everything as i am new to Alfa Romeo systems and a lot of the terms used are from expert people.
I will try to add information that i found useful for me and that you can use or not.

Refering to your text :
  • Purchase and install the RDNA selector for a Quadrifoglio.
    For the 2019 models like mine, there is a change in the DNA module that is now going through the CAN bus where before it was an analog switch (see schematics here and part numbers reference here(GSX means Left Hand Drive cars))
    • Reference for analog switch is 156.129.231 (MY16 through MY18)
    • Reference for CAN bus switch is 156.141.589 (MY19 through MY20)
  • I have found no online reseller for the 2019 switch as of today.
    There is a link to the EPER (Fiat/Chrysler Technical reference) here but it does not account for MY19 models (still ?).

  • Option 2: (Modify your existing DNA selector.
    The described DIY modification is only applicable for models with analog switch MY16 through MY18.
    Some older models MY16 were already equipped with DNA with 3 switches and just need to enable DNA rotation to Race position.
    I don't know if the 2019 switch can be modified by a DIY solution.

  • Hide your DNA modification
    I have found an italian forum (here) where a guy installed the original DNA cap onto it's R-DNA switch thus removing Race marking. Not perfect but a smart way to get the mod not visible at first glance.
    I have found nowhere the process to remove the DNA cap, seems tricky.

  • Step 2/2 Configure the ECM to allow the RDNA selector to toggle Race mode:
    You can perform the ECM configuration modification without changing the DNA.
    The modification will not be accessible/testable up to when the R-DNA is in place.
    This will secure your money in case you can't go to the end of the Proxy/ABS process

  • you will need to connect to the ABS module using the gray (#6) cable. Perform the 3 calibrations
    As far as i understood correctly the discussions in the forum (here), you need to ensure that the driving wheel is in 0 position and that the car is laying on a flat surface for the process to complete without error.
    The 3 steps of calibration (here) are:
    • Lateral and Longitudinal acceleration sensors
    • Reset steering angle
    • Pressure sensor calibration
Those are my additionnal findings that could help to better master the process for less skilled people in Alfa Romeo programming and modding.
My Alfa Romeo tools are under order but we are in August and everything takes longer to be shipped and be delivered.

If anyone with a 2019 model has done the modification and would share the results, it would be fine.

EDIT : added links to information source references

Adding info discovered/gleaned from the other Race mode topic...


2018 Ti Sport Q4 - North America:

Byte 88=AC (Stock)
  • ESC enabled in all modes
  • A = A in ECM/BCM
  • N = N in ECM/BCM
  • D = D in ECM/BCM
  • R = No change
Byte 88=CC
  • ESC enabled in DNA modes
  • A = A in ECM/BCM
  • N = N in ECM/BCM
  • D = D in ECM/BCM
  • Race Mode includes:
    • N in ECM
    • D in BCM
    • Disables FCW
    • Disables ESC
    • Disables Auto Start/Stop
Byte 88=EC
  • ESC enabled in DNA modes
  • A = A in ECM/BCM
  • N = N in ECM/BCM
  • D = D in ECM/BCM
  • R/ESC off mode
    • Race mode is not indicated
    • "ESC off" mode includes:
      • D in ECM
      • D in BCM
      • Disables FCW
      • Disables ESC
      • I don't think it disabled Auto Start/Stop
I'm more than happy with EC in 88... until we discover more configuration options.

So, am I reading that if I have a 2019 2.0 TI, the RDNA switch is not available? It is a different switch from the previous years? How would I get one?

I think that may be correct, but I don't want to incorrectly state something I don't have confirmation on. I believe that it's an actual CANBUS node, as apposed to the older passive device. Not sure where to procure said switch though. Dealer?

Yes MY19 need a new one based on CAN bus interface.
Look here, you will see the 2 models schematics.
Look here for the reference 156.141.589 (for LHD cars).
I am also searching a part seller in Europe.

Ok, I would be interested in knowing where to get one. I know that Alfissimo mentioned he had some on order, and not sure if it was the older or newer version. Maybe he can comment on this when they arrive??

It’s only models with the mono static DNA selector that have the DNA selector set up as a CAN node. @MacGeek stated that he believed this change was coming to MY19 vehicles here in the states. I don't think that ever materialized. I do believe the change was made in Europe though.

As long as your DNA switch acts like a switch, (IE: clicks when you turn it) I think you have the correct DNA selector.

Race mode works well with paddle shifts on giulia 280 Ti?
In the mode that I am running in, EC in byte 88 that does not turn on Race mode, the paddles work.

I finally did a strong launch this morning in D + ESC off, launched at about 2k RPM. It pulled strong and the shifts were very crisp. Depending on how this evening and tomorrow morning go, I may have a chance to do some testing and data logging of the different modes and their behavior.

What do you have on the screen in Cluster? When i turn on race mode i got Gear indicator, others got speed, anyone knows how to turn on speed instead of Gear? I got CC in byte 88.

From a QV specific topic somewhere it sounds like that has to do with a software update. Not sure what version.

I have these showing as RDNA switches. Which one is which and where to find them other than dealer? They cost about 72 to 95USD when I look them up but no way to order.
