Should have great 0-60 numbers with less spin. Can’t wait to see.

 

Today was really hot and humid and the car was a dog off the line no matter the style/mode. But once the revs get up in 1st and all through 2nd the car is pretty nuts in race mode with tc on. The only issue I noticed is the 1-2 shift in WOT can cause fuel cut due to TC and the violent shift. But I think it can be managed. And the computer still does a much better job managing slip vs my right foot.

 

Are there other things that might be visible and maybe controllable this way? For example, setting the suspension hardness in A or N mode, selecting QV race-suspension setting, selecting the headlight middle beam on, and forcing the headlight middle beam off.

 

Probably. It's just a lot of logging/analyzing/testing/etc. I do plan to try to tackle the suspension settings next, with the main goal of being able to use soft with race mode.

Way to go, I think that is a really professional result and I'm impressed.

Is the TC/ESC a binary thing - i.e. either on or off?

I've always thought a "Dynamic+" setting would be absolutely perfect in this car, I would want about 50% less traction and stability control than Dynamic mode, but not fully off like in RACE mode.

I'm actually not quite convinced that ESC is totally off in race mode. I'm guessing there is more granular control to be had, but it's a lot of guessing and (possibly dangerous) trial and error without access to the firmware that ESC module uses.

I think if ESC was completely off in race mode your torque vectoring differential would be rendered into an open differential. That is probably not what you wanted.

I find myself putting my Q4 in D in order to navigate turns at ordinary speeds in order to stop the wallowing that the car tends towards with the suspension soft. If I drive in D all of the time I can't get enough fuel economy to make it between top tier gas stations--one of several reasons why I did not buy a QV.

 

Can you do some logging about the exhast flaps. Would be excellent to also individually control it without having to deal with another tool.

 

So basically you are tapping into the canbus and sending the ESC on/off signal live. Awesome work!
Do you have the ability to bind the signal into one of the car buttons (say D mode) and write it permanently?
I ask before buying the same tools and investing time.. as it would be the only functionality I'd be interested in.

 

Yes, but instead I tied it to the left stalk (LDW) button. If I push and hold it for 3 seconds it toggles ESC on/off. Normal presses enable/disable LDW as they should.

Edit: depends what you mean by "permanently". The code and whatever canbus module you go with will always need to be present.

 

Very cool! I’d be interested in more details. What CAN adapter did you buy? Where did you tap in? Is there one spot that gives access to all modules or do you need separate taps for each? How did you go about figuring out the right codes? Is there no problem spoofing commands? There’s no check that they are coming from the right module?

Its not a money thing. I just would prefer someone implement it that can do it right and I don't really want to "support" it. Although I don't think any of them would have issues figuring it out on their own, either. PS if there's someone in the Columbus Ohio area with a 2.0 that wants to test, hit me up. Takes < 1 minute to test and nothing is changed/modified /stored on the vehicle.

 

I would absolutely pay for a mod that would allow TC/ESC in race mode.

 

This is exactly what the QV needed and should be standard. A simple on/off TSC button instead of start/stop. You just basically solved the launch mode issue. I need one lol

 

I'll push the code and instructions to GitHub sometime in the next few days.

 

That would be really cool.

 

This is fantastic news for all owners, and cant wait till someone has a go and sorts it out on a 4cly car

Nice work beaups, I may try this on my Ti. I don't have LDW, so I am assuming that I could bind it to the right stalk button instead as long as I am not on the Trip page?

Is there a standard OBD2 port in the trunk? I haven't looked.

 

How about button combos? Right stalk button and rear fog light? Both paddles?

 

I will check this out in the next days on a 2.0 TB Stelvio.

 

DNA_AWFUL... ?

 

I did some testing now on Stelvio 2.0 TB with the help of beaups code.
The result is that it doesnt work.
It works fine in detecting dna modes and sending messages to ESC control, but nth. happens.
Maybe its because it actually doesnt know about race mode, so at first race mode should be enabled.

What do you mean "nothing happens"? Do you get the ESC off light or? The code doesn't put the car in race mode, it only signals to module to put car in ESC off mode. It looks like that module then signals the instrument cluster over the primary can bus.

 

You can find my fork here:
github -> MageCoder/giulia_ESCape

Will be updated from time to time.

 

No i dont get that ESC off light.

 

OK I replied to you in PM. Hopefully we can figure it out.

 

My hardware just arrived. I have Stelvio 2.0T EU version. Is there a way to contact you in some messenger (Skype, Viber), so I can get some insight on what to try

 

sent you pm

 

PM me too please.

 

What connector do you use in the trunk?

 

 

Nice! so 2 and 5 for CAN. Do you use 10 or 12 for the 12v?

 

Yep. The wires running to that connector aren't bound together tightly or well so it's very easy to tap them.

 

So you don't really need a "real" cable... just a RS-232 male plug with 2 wires and another 2 wires for the 12V to the arduino

 

You don't even need an DB9 cable for a more "permanent" install. I connected power to barrel connector and did a pigtail to the can connectors (not the DB9) on the arduino shield.
