Why are there not full frame or at least hybrid turbo options and more robust custom tuning options for the 2.0T Giulia after a good 2 years? I'm finding it rather annoying that nothing has came to the market with these with such an easy turbo location for replacements and easy ecu to deal with similar to continental simos ecus. Even the downpipe options are sparse and it's only 2 bends with a funky turbine flange. This engine is after all fully forged; crank, rods, pistons with oil squirters which could easily support 500whp/450wtq with proper calibration/fueling.

@Dj-oohlya I have now reversed the Turbo actuator % reading from the QV PID and also multiplied by 10 to get the scale right and see if this now indicates WGDC%. Does this make sense or look as expected? The lambda readings are not accurate as on MES for QV you can only connect to 1 bank/ 3 cylinders. This probably messes up the 2.0 reading somehow so I have deleted them from the log.

@Triumph23 i am not necessarily saying that it should be reversed.. just what im used to, reading the other way around. Ultimately who cares what the scale is 0-100 or 100-0 as long as it is relative to wgdc, and that is the question. Are we reading wgdc and then HOW do we read it? Do we interpret it using wgdc logic you read about or some new Italian logic we dont fully understand. 🤷🏻♂️
Like for example lambda of 14:1 afr basically? Am i the only one bothered or confused by it? Am in reading it correctly or is it a calculated value based on some logic i dont follow?

Based on what i am seeing and applying wgdc logic i know i would guess that turbo is capable of more. Wgdc is 50ish when maintaining the boost into high rpms so there should be room for some more.
Any way of finding out what turbo is stock? I am thinking of calling Alfa dealer parts to ask.

The gas pedal sends a torque request to the ECU. The ECU interprets the torque command and a host of other factors to determine a boost setpoint to which the wastegate is controlled to achieve.
It's much different then old school turbo setups with the wastegate just staying closed until it hits its pressure.
Just guessing here, but I believe there are protections in play to keep the turbo from running past its curve, protections on ensuring the wastegate is actually controlling, protections on the plastic intake, emissions factors, and whatever else they ran into during testing.

I'll also repeat what I have been saying years - we will continue to be in the dark until we are able to attract a tuner that wants to be open (like Cobb) and expose the tables and sequence of controls and not obsessed with keeping everything top secret like the current crop of flash tuners.
@Alpha so do you think there are parameters that we cant monitor or are you saying that since we cant see tables and what parameters interact and how we are blind? Or perhaps both?
I am hoping that all the parameters are out there to log w MES but we may not be able to understand how they work together without tables.
I am not disagreeing w you though, and agree that things are looping back and feeding off of each other in tables we cant see. I wish we had Cobb ATR like solutions but we know its not gonna happen ever.
@Triumph23 is there turbine speed or rpm in there to log? While it isnt maxing that doesn’t mean that it should be maxed out or could be and put up with daily use long. Have you logged your oem map? Do you have logs still? Do you wanna look up and compare actuator % and lambda and boost and ign? Would give us an idea how much harder turbo is pushing to reach 28psi now among other things.

@Dj-oohlya , I have some stock logs from 2 years ago but that is the 200hp version with a max boost of 18psig. Not sure what parameters I logged as I did not have MES back then just Torque pro. I will look at it later.
Also no turbine speed of turbo blades.

Turbo Garrett GT2056Z specs // not the turbo on our cars. Error
smaller than in my 18 wrx which has a GT2259

If we are to go off pics and whats been removed off the car then whats better than ebay linke @Triumph23 provided? Apparently those are off actual cars.
Your pics look slightly different than the pic on the turbo specs link. And that link was found by using ebay part number and turbo model. That bottom right number is the part number that Alfa parts gave me today. On your pic.
On another pic you can see 56 and 73. Lol

My pictures and pn plate is same as link triumph provided. Thats where i got them from similar links.

As for the turbo compressor outlet I.e. air intake plastic manifold , the temperature I measured at the intake sensor was about 140 degC at peak redline so that would be plenty of margin but then temps at the mouth of the compressor may be a tad higher before the air expands slightly perhaps?
If air temp is 140c and air is at that temp due to heat exchange between it and metal turbine components, then the housing and metal is likely even higher temp no?
Truth be told i think it is metal on plastic same way on my wrx, also a 2L DIT just boxer/flat layout. Must be the industry norm nowadays.

Those are pre ic air temps. Im glad to hear thats all they are. My temps on jb4 logger are scaled wrong. I see 215 to 230 degrees but terry has rescaled them many times now so very unreliable numbers on this logger.
This plastic boost pipe is not to be confused with plastic intake manifolds that manufacturers have been using for 15 years. This is right off the turbo outlet pre intercooler

Yes, charge pipe is what its called in Subarus. I left mine stock plastic, measured at 190F with laser point thermometer in Arizona. Thats 6-8” off the turbo.. the higher you go towards the ic Is less hot and gets as low as 140f right before ic. These are surface temps of plastic used to make the charge pipe. I figured metal would be even hotter.
I just got the Giulia so will be testing surface temps on its charge pipe too as i get a chance to have some under the hood time. I am expecting it to be by the firewall, have not even looked hard. I do know it doesnt have a dipstick but it has two coolant reservoirs. To balance the car i think 🤔 😆

Cant find grey obd adapter 6 and blue obd adapter 5 anywhere that isnt the uk. I also ordered me emotion+ and a CT tune. Anyone else out there with a US spec Giulia who went through the process effortlessly preferably?
Hopefully they dont cancel and refund my order because of ‘rona19 like the iDatalink guy did.

Thanks guys. The UK Ebay seller replied and seems like issue was having it shipped via tracked mail. So that took care of that and i just reordered, total 60$. Hopefully it doesnt get cancelled.
Alfissimo had the green odb kit but at more than double the price, in America.

So how different are North American Giulia Ti and European Giulia Veloce? I find differences in engine power specs when comparing the two, the former 280/305 and latter 276/296 and even the rpm where those numbers are achieved don't match. European spec car gets crazy gas mileage too and American sister doesn't, what's going on?
Is it just a matter of tunes? Or more? How about other options like remote start or automatic door unlock and automatic shutting off when idling too long? Do you guys in Europe share all these options? I hear you don't have some leather trims that we have which is why I ask plus the discrepancy in engine power is somewhat confusing.

I dunno about the power, but I believe that there is no equivalent of EPA fuel economy numbers available in Europe. European fuel economy numbers are achieved only under ideal conditions (similar to CAFE?), while EPA fuel economy numbers are much closer to typical driving conditions.
Reportedly a high flow cat will gain you 2MPG highway in a 2.0T Giulia. Too bad there isn't a smog certified one available <sigh>. I believe that some high-end cars come with high-flow cats, so it is not as-if such devices cannot meet the requirements at least with the right tune.

How about passive unlock when close enough to the car? Do you get that in Europe? Sporty stitched leather trim? Does Veloce come manual??
Does anyone in US have a European based tune on a US spec car? Wonder if there are any issues and slight nuances with the two.

Whos gonna tune the big turbo upgrade, assuming its possible? I cant even find a custom calibrator on oem setup let alone a whole new setup.
I dont expect much as far as performance upgrades on this platform because the market isnt there. But nothing is stopping anyone from buying a bigger turbo, custom fabricating fitment and with motec being able to tune, but this isnt practical for everyday enthusiast.
