IS200t tune
#2401
With this tuning program it definitely needs time for R&D since the tables don't have any definite values . The boost table just has a bunch of numbers with no actual value such as psi or bar, so its hard to figure out what to add (kudos to Tony and TTi). He adjusted the fuel at certain areas, but then we were faced with another table that will re-adjust the changes, so in all theres a lot of protection/limitation on the stock ECU that avoids you from really getting those parameters locked in. With a bit more time and research he will be able to figure out the tables and then we will try it again. We had 3 hours on the dyno and made around 5-6 passes since most of the time was spent figuring out the tables and then writing the file. I did see a drop in torque with the de-catted down pipe, but it did pick up some power up top, also if you look at the runs they were all done at a higher rpm and our car makes peak torque really early in the rpm range. We did have a discussion that if we are unable to find a way around the limitations or get a better tuning program we will then try to do a custom tune with the BMS since it makes a lot of wtq and we will adjust the a/f ratio up top to help with peak whp.
I was discussing various things with Tony, and we came to a conclusion that EU version ROM like mine are producing more power than USDM and JDM, due to the fact that more tables are unlocked, could be because the creators of the master software are Russians and have EU ECU version so most of the R&D was done on it....God Knows but the fact that EU ROMs are making more power have been proven with my car and few others.
I disagree with the fact that your downpipe is a bad choice mine is literally a straight pipe and I have no Cat all the way to my Q300 and look at my TQ...one of my runs I got 299.2 WTQ.

You got it Nuke! The Euro ECU does have that huge advantage, hopefully soon there will be a way for us. I have faith in Tony lol. The reason why I said the catted seems to be better is due to the fact that with the BMS tune there was only a 2wtq difference between stock and de-catted, but I did pick up power up top since it’s free flowing. This engine seems to like the back pressure torque wise.

Not to be condescending but we definitely have plenty of “hidden” power. It’s wishful thinking to think a tuner would pull out 100whp the first time around. Most companies are still trying to break the 10th gen fk8 ecu. I happen to completely disagree that EU’s ecu’s are different in terms of being more tunable. I’ve heard to many other excuses

I mentioned this to my tuner as well and he did agree that the euro ECU can have unlocked table maps which can be adjusted. This tuning program just needs to be studied a bit more or maybe find a much better alternative because even to a tuner with over 20 years of experience he had some difficulty maneuvering around the tables. We are not making excuses let’s stop bashing on other people’s opinions. We are working together to figure this out, I would still like to see a dyno from your car with the BMS stacked tune, share some information with us!

I think its a matter of R&D more than experience, I mean tuning in concept is the same with almost all cars but ROMs of cars is whats different, and lets not forget software support, take Evos and STIs from experiance they have allot of software support even free ones that has almost ALL tables u locked and explained (ECUflash), i think we will eventually get there but not soon this will take allot of time, and the public need to show more genune interest in order for these softwares to be developed and in order for tuners also to invest time understanding them.
No one is making excuses for why power difference between cars but rather we are trying to figure out what we know so far, in short I agree with you 100% about the opinion part but i hope we all agree

I have uploaded my TTI Stage 2+ tune and will be waiting patiently to see what happens next.

And it's available https://www.ovtuned.com/collections/...t-is200t-turbo $959 which is a little over what I had hoped for but honestly they can charge that because they are the only ones to offer this type of product.

A comparison between a stock 8AR-FTS and the TRD TG20 SPEC B. You can see the size difference of the turbocharger.
#2413
That trd motor looks sexy and that turbo looks at least an 1/8 -1/4 biggerI do wonder what other modifications they did in general Could it be as simple as a bigger turbo and a decent tune from trd?
#2414
Lol again this is my opinion. The turbo isn’t bigger. It’s the same turbo however it’s very obvious the trd turbo has more bore just before the compressor turbine. Giving more room to cram more air with bigger turbines/bore.
#2415
The Hybrid turbo TTi is working on is basically what TRD is doing with theirs. I would expect TTi to be a much cheaper option however TRd might cover it all under warranty. I wish I could find more info on it that way I can definitively say
