It's soul red with beige (greige) leather, premium trim. I think it looks real nice.
I notice when coming to a stop, and then starting.. my tach goes to zero, stutters then surges.. is that normal?
Under the back cargo floor, those foam inserts protect cables etc.. is they an after market replacement to enlarge those cargo cubbies?
That SD card reader in the center arm console is used for navigation loads, any way to use it for anything else?

What's the difference between the sbase turbo and the turbo S.. is it the same engine with simply different tuning?
Is there any hacks to convert and what would that entail? What parts would eed changed if any or are they that different??

 

Got this info researching the Mazda 3.3L Turbo engine: Any thoughts?
<https://www.reddit.com/r/mazda/comments/12oig04/new_33l_inline6_engine_technical_specifications/>
1. Uses a standard throttle body, no valvetronic style. Combustion chamber is an evolved version of the 2.5t PYT engine. VVT operates the same way as the current Skyactivs. Cylinder head uses an integrated exhaust manifold with two exhaust outlets that feed a twinscroll turbo. Intake ports are individual per intake valve like the majority of current Skyactivs. Boost control is the same style as the current 2.5t with a wastegate and recirc setup. Fueling is typical GDI(no port injection) boost psi is different between the two by about 4 psi, and they are mechanically the same.
2. they are the same mechanically, than a tune from BMS, Cobb or equivalent could probably take the standard models to the 369lbft on premium fuel.
3. a tune would be able to get it to the same level between the two, but there is a lot of interplay between the ECM and TCM to get the transmission to operate correctly for 1st gear/reverse.
4.. to make it engage correctly without feeling poorly, the torque modulation has to be very accurate, or it will have really bad shudder.

I get significant shudder now., so maybe it's designed for the S trim, than handicapped to the base and that's why I get the shudder.

 

Welcome to the forum

Iam only responding on one part of your query . Unless you plan on learning yourself and hopefully take a trading course I don’t recommend what you are contemplating. The http I started to read and found so many bad theories I stopped reading it.I would rather read the Sunday paper funny page!
There are an only a small handful of individuals even capable of tuning a TCM file to match the ECU and not risk damaging the transmission and it ain’t on any Mazdas that I am aware of. I know most all of them And it requires DYNO time and about 2-3 days of calibrating and reading a few dozen data data logs . $$$$$$$$

And the mere fact that you believe the advertised power rating shows me that while your heart to mode is in the right place your knowledge is not and better be prepared to spend several dozen Benies$$$$ Try research by looking into the truth behind auto manufacturing power ratings.

Sorry I am sure you will be able to find plenty of internet wizards that may disagree.Simple question is ask where and who taught them EFI/EFI Performance Calibrating? My guess is either self taught or the “experienced friend “ taught them lol


Goodluck with your project

 

I wouldn't contemplate trying, just noting the engine hardware appears the same. I got the base turbo engine to save money and on the gas, but it was interesting to read the difference is in the tuning/calibration.
I was a Field Engineer for Prime Computer in the 80's, the only difference in one mini was 100K and a dip switch speed setting. It appears that almost the case here..
Just what would be involved, only the Mazda 3.3 Turbo engine development engineers might have that capability.
As for the shudder, I now know it's not turning the I-Stop off. I am surprised with it on, the engine actually turns off when one brakes and stops the car, like at a light/stop sign in order to save gas.

 

Auh ok not sure what you posted??? First it requires to be able to have cracked the codes to even enter the ECU. There are some that can but most are limited not global access. Lot of bragging about their capabilities on the internet as well as very nicely set up web sites>
Its not engineers that develop ECU program for Mazda ECU from at least 2015 to present aprox. btw.
Still not sure about how you assume that the engine specification as far as power ratings are accurate???

I can tell you having done many Mazda that what they advertise and what is actual is ...well padded.

About SAE J1349® Certified Power

 

What is needed to alter one to be the other? That is, only parts needed other than replacing the entire powertrain.

 

There is no real supportive empirical data for that thought! And no evidence or anyone offering a comparison of ECU PIDs to confirm or disprove one way or another the Mazda ECU mapping files . This would or could only be done with a ECU program being able to enter the files down load them and compare them. Oh about 100 + plus hours

lastly disregarding some important info ration that may shed input in some theories of power advertised information and basing on different parts is …..well high scoolish thinking .

Have members considering all these thoughts and unsupported theories ever seen a complete few second data log to see what an ECU programming does?




ok well good luck with your project.

 

One significant detail is that the curb weight of S models are stated to be 4863 lbs, and all models with the base engine are 4709 lbs.
So maybe there are some mechanical/parts differences, it likely is just not tuning.
BTW, I intend no such project, just asking what differences are known.

 

Um really???? LOL

you do realize if you go look they do not state dry or wet (fuel) and what reporting agency did the weighing . It is also not a certified weight. This also goes for the other performance related specification? There is no regulations to fluffing to a small degree many of the reported specifications. LOL Dude you are so reaching but I do enjoy your posts. It allows me to set more EMPIRACL information then random far off the cuff theories. Sorta like a group on my Quantum Physics forum that when they get way out of reality, we call them the Flat Earth Theorists.

 

Trying to separate the chaff from reality.
