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.
Lack of bigger turbos and tuning. Discuss.

Alright here are my logs. I didn't realize how big of a stretch you need to get a full fifth gear pull, especially if you live in the city.
The first run is in 5th gear and I stopped at 5500 rpm cause I ran out of space.

Second run is in 4th gear with two pulls. Then, the mall security car started coming my way and I left
. I'm starting to understand why people move to low density areas.
Those hiccups in the throttle are due to a bump that gave me some airtime.

No need of any distributor... you just download the software.
On Multiecuscan - Diagnostics software for Italian cars you click on BUY REGISTERED LICENSE (50 EUR). You don't need the 230 multiplexed unless you plan on working on a bunch of old Fiats and Alfas.
Pay, get the code in the email and the download the software from that page.
As cables, you need a USB to OBD2 cable and the blue and grey OBD2 adapter cables. You'll find them on Amazon/ebay.
Do you have the csv file? I cant stand datazip. Says boost of like 45psi and just a pita to use on a telephoneAlright here are my logs. I didn't realize how big of a stretch you need to get a full fifth gear pull, especially if you live in the city.

Do you think there is a different lambda to log? Your lambda shows close to 14:1 at redline. Stock giulia at redline is like 11.5:1Here you have ec p2, intake, exhaust.

You can download csv files under download. Data is right under graph. Under data is download.
I on the other hand love datazap.me.
Thank you for your help. I thought about that but then i have to carry with me a windows device to run and log in the car no? As i understood the multiplexer would be all i need otherwise and then download the data from it to laptop.. am i wrong? I dont mind paying for convenience only, plus i have other cars i could use it on if need arises.
Your logs look like you hit 28psi boost if my math is correct. This is ec ph2 and what fuel was this run on?
😂
i find hwy on ramp is good way to log but i have ever done it in 3rd on a 6spd manual, 25-90mph.
Id agree. Certainly on par with CT log and not better. They arent best of logs these last ones. But id give them 10% for drivetrain loss off their 310whp claim, so 335ish on the crank at the best of conditions. I dunno where or how they come up with 390bhp and 310whp. Thats more than an awd drivetrain loss.

All the multiplexed version does is spare you the adapter cables... but you will still need a laptop to connect it and to run MES.
Yup this is EC P2. I have an open cat-back exhaust and EC air intake. Gas is Citgo 93.
Peak boost seems to be 43.34 - 14.39 = 28.95psi at 3.5k rpm.

@Il_Conte , you peak figures look similar to my CT log. The max peak boost I hit was 28.5 psi @ ~3k rpm so a bit earlier. In the first log you hit ~(43.28-14.5 = 28.78) @ 3254 rpm, not that dissimilar. I agree with others that the EC logs look on par mine in terms of boost/power delivery. I can't see how they tested 390 CHP. I only have a Sprint filter and an axle back road legal Remus sport muffler. I have boost earlier in the rev range which holds steadily across the revs all the away up to 6k rpm gradually tapering off. I understand EC are well regarded and I considered getting their tune so I am not criticising their work, just thinking pragmatically as to what the measurable benefit is and how they met their claims. I did not want the V2 intake as I am not a fan of open air filters. Makes no real tangible benefit except for intake sound IMO. If you look at my air flow rate, its smooth all the way up to the red line. I am curious to see what the stock and BMC filters are like. I have those too, which I may put back in and do some runs to see if there are any differences
@Dj-oohlya as quoted above, you still need a windows laptop to log everything as the Multiplex adaptor which is plugged into the OBD port will need a USB connection to the laptop for MES to log the selected data. Multiplex adapter does have Wifi and BT capability but, data cable is more reliable and faster especially for Proxi alignment so I never set up Wifi or BT. MES is great once you get to know it. Good thing is they keep adding support for more modules and parameters as the develop the data for the Giulia modules. For example they recently added support for the Q4 drive and a few other modules with the 4.6 version update. Like said above, you do not need multiplex adaptor. I just find it easy to use especially for Proxi alignment and access to all the modules using just one adapter rather than keep swapping cables. You can just buy the correct coloured cable adapters you need. I posted about how to get MES in another thread in reply to you, perhaps you missed it.
Go to Multiecuscan - Diagnostics software for Italian cars and just download the latest version for free and you can play with it in simulation mode and see what you can/cannot do.If you then buy a licence on their site you can activate it to full version. You can buy the cables from Amazon or from Alfissimo (forum member - send him a PM) at his shop. Hope this makes sense.
I'm always running on ron98, sometimes on ron100.
But ec didnt set igniniotn on ron98.

Does the ECU self adjust based on fuel actually used? Don't fully understand how a tune made for 95RON works for higher RON/Octane rating. Can anyone explain in detail?
You can run on higher, but on lower not.
I didn't see any changes beetwen 98 and 100. On 100 maybe pops are louder [emoji16]

Totally depends on how the tuner or oem sets timing targets. Audi, for example, sets timing targets very high for hopes of best efficiency possible if the right fuel is provided and they rely on their very proficient Ignition Knock Control (IKC) system to retard timing as needed. I routinely see California 91 octane cars knk retarding 12 degrees of timing on oem tune. This would have been unheard of 15 years ago.
So if you set timing higher than a traditional 93 octane fuel can hit, then rely on knk retard then the vehicle can take advantage of an e85 or race fuel mix. Generally if its knk retarding 5 degrees, you'll get that 5 degrees in extra power (roughly 15hp) by adding, say. E30 or a good octane booster.
In my b8 s4 we had people running upwards of 32 degrees of timing with 23psi boost on e40. The alfa is something ive never seen. Oem shows 0 degrees timing advance and tunes only 4 degrees. ... and no knk retard so doubtful better fuel will help much.
Many cars have maps programmed that run aggressive timing that the knock control system then pulls when lower octane fuel is used... I haven't really seen any indication of this happening on our cars though

At what point in the rev range is this timing retarding you reference ? Is it at redline where we are seeing about 4 degrees of timing 'advance' in the tuned plots? I am slightly confused by timing retarding when others were talking about timing advance at peak. Sorry if this is a daft question.
I can certainly say the engine seems to run much smoother and better with Shell V power compared to the lower Octane fuels I have been forced to use occasionally for a couple of tanks at the same time.

Also when I have used lower RON 95 fuel I found the fuel economy was better for the same average driving that I do everyday for the same tankful of fuel. I always thought it was a bit strange. Could ignition timing have anything to do with this on the lower octane or say factory tuned octane fuel (In my UK handbook they recommend 95 RON or above)?
All i can contribute is that CT tune is made for UK 95RON or ideally 98RON, per their email this morning.
I didnt see any knock control in any of the logs either but perhaps no one is logging the necessary parameters to show it?
Some of you guys running 93oct in usa could add a splash of e85 (1gal-2gal/full tank) to see if it helps with (full) timing advance. But we arent sure what that is either, we are only seeing 3-4deg uptop and comparing that to other tunes. Thats just real life/current timing.
Where are you guys seeing ignition timing retard/pull? Are you looking at ignition timing?
