Lack of bigger turbos and tuning. Discuss.

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.

The stock run they have let off as the peak hp is already achieved to confirm factory claims. The remap pushes the peak further up the rpm so they kept going to limiter I am guessing to see what it can do. Tbh if you see the other maps in Europe they make similar gains, so I see no need to inflate any claims whatsoever.

I persoanlly just never trust dynos from anyone. If they were a proper tool to compare things then I would imagine OEM's would follow a standardized test (i.e controlled environment) and use them for marketing.

Don't get me wrong they have a place and are great for using as percentage gain measurements if done correctly, however I think they are too easy to manipulate (even by accident)

However all that said i am sure they still made worthwhile improvements. Managing to move the power up like that dyno shows seems like that tune is 100% worthwhile and would greatly improve the driving experience in my opinion

@Go_a_way1 , I agree dyno are subjective. I have dyno tested my car 3 years ago and really struggled find somewhere to check how much my car was making as stock in the 200hp guise in Europe, as it was claimed it makes 220+hp from the factory. I finally found an experienced dyno place where it tested at 223hp. I only ever use dyno as comparison. Most recently my data logging with MES earlier in this thread validated to me the Celtic map is actually delivering all that it promises. In my case it was a massive jump from 223hp to nearly 330hp. The 1/4 mile tests I did showed a trap speed increase from 96mph to 106mph which also confirmed the increase in power was valid. Personally, I trust Celtic as they tune cars of all shapes and sizes day in day out, from basic diesels to supercars so they know a thing or two about gaining power safely and smoothly. I am in no way connected to celtic. I just am a happy customer. For me they ticked all the boxes for what I use the car for.

Yeah for your model its a huge increase since its the same engine anyways so its so worth tuning haha.

I have a question if anyone know since we are on the topic:
What is the next limiting factor after the turbo for making power? If I was to guess it would be the transmission not being able to handle all the extra power?
 
#336 ·
Transmission ZF 8HP50 is rated to 500Nm conservatively, same(well similar) transmission in BMWs are running tunes much higher. There is apparently plenty of headroom. Tuned mine is under 500Nm.
 
#338 ·
I don't think the ZF transmission is the weak point. If you want max power then you could start with a high flow cat and free flow exhaust. I am certain though you would lose some of the low end torque for normal driving despite what people say. Exhaust flow/volume and torque have an intricate link and to improve the factory design will need some thinking and testing.

From watching the boost build in this car during normal driving it amazed me how often it went into boost even if only a little so I think removing all exhaust restrictions might not be as big of a negative effect in this car then in most due to how quick the twin scroll can spool. It's fun for me to speculate but I will never be able to test this because I don't want a super loud car haha

So Eurocharged also has a handheld and a tune combo for 999$, anyone tried them on any platform including the Giulia? I emailed asking some questions but got a basic response about +40/50 power increase.

They also mentioned raising the rpm and transmission maps. I wasnt aware transmission tuning is possible yet. 🤷🏻‍♂️

I have one in the mail I can report how it works. From what I understand the rev limit raised is when in park and in manual mode since they can not program the actual TCM. The shifting will be effected by the engine torque so they have a limited amount they can do on the ECM side. From what others say it shifts smoother so we will see.

@Go_a_way1 keep us posted and i expect a review of the process.

I have Emotion2+ on the way from Celtic, its about to leave UK and head for this side of the pond. Will review it in time too but i plan on logging first with MES before flashing any tunes.

So far we got guys running EC, Eurocharged and Celtic for ECU remap tunes. Am i missing anyone?
 
#346 ·
@Go_a_way1 i see. So no one with Eurocharged?



They say they offer custom maps upon request for 50 quid. I will definitely request. (y) Didnt ask about traction control, i dont mind that on.

@DeXa are you running Squadra? I just read an article about them and Giulia with 350hp as oem, but it never materialized.

@Go_a_way1 you had Eurocharged in North York if you’re in Ontario, same price as EuroCompulsion. I think i have seen and read a few tune reviews on Audis they did, good stuff. Never knew they did Alfas as well.

On a diff note, i used to live in Toronto almost 2 decades ago. Beautiful city crap weather.
 
#350 ·
@Go_a_way1 oh i have, especially Audis. Great tunes and most of the RS3’s i follow have been tuned there, not necessarily in Canada. Seems like they have great reviews and Slav and Vlad (guys in Ontario shop) are eastern European, which is where im from originally. 😊

I will give them a call tomorrow to find out if its just flash tunes they are doing or if there is some custom tuning possible, because like i said, I’d like a truly custom map, possibly an ethanol blend. And if they could put that in D and 91oct in N id be a happy camper.

Does anyone know of any bolt on turbos (physically fit) that would work with the giulia? I have a friend who does crazy fab work and builds 1000+hp drag cars so if anyone can figure out how to make it work with the electronic wastegate it would be him. He inst cheap though :(

@Triumph23 .. i had actually heard of Eurocharged Canada and USA. Never heard of EC until Alfas.

Eurocharged does full custom ecu and tcu (dsg) mapping. They have a dyno. They are a legit tuning shop. Just type Eurocharged canada in YouTube. I wrote them an email and asked about ethanol and custom mapping for Alfa. We will see if and how they respond. I can and will call to talk to them rather honestly. I went to school to York university and they are a mile away. Lol.

RS3 1/4mi

My emotion2+ is in the mail anyway at half the cost. Also CT do custom tuning too they say on their website. Is it possible to make it where the tune is only in D for example? Or 2 different tunes, one spicier in D and one in N more conservative? I mean if EC can do it with v1 and v2 then it must be possible no?
 
#355 ·
@Dj-oohlya . I don't think CT can put different maps in DNA modes. I asked. Theirs is more straight forward tuning which is reflected in the cost I suppose. Custom tuning yes, but check with them.first how much they can custom tune.

But is the air flow, fresh and exhaust, there to support a bigger turbo?

Yeah, all of the bolt-on devices are great and all, but what about the intake/exhaust manifold cfm capacity? How about the cylinder head passages? All the bolt-ons in the world won't fix those.
