Visconti Tuning - Latest BRZ Flash Info

[CircuitJerk]

I ran my stock map for a couple weeks on the P&L catted header with no issue.

I fitted spacers today to both sensors on the header, no CEL came on while on stock map and my temperatures are back down to normal.

AFAIK, there is no temperature sensor. It's a calculated figure from various sensors so may not actually be accurate.

The spacer on the secondary sensor is fine though. I believe the CEL was triggered only by the catalyst inefficiency reading from the secondary sensor.

You are certainly correct, hit the dyno, dropped by 8kw and 10nm torque. Removed the spacer on front sensor and all went to normal.

Thanks for the advise.

What are you getting at the dyno now?

What would be the recommend EBCS I could get for the Full blown kit? Do you all offer one?

Will have to go dyno run v1.14b4 again, will post results soon.

V1.06b3 Stage 2 installed.
This flash has a smooth quiet idle with the new EL Header.
The car feels like it has more power everywhere in the torque band, the pull is excellent.
Data log in a few days, thanks John!

With 91 pump gas, I got +4whp and 3wtq

The driving changed dramitacally and the car is much fun to drive, feels like another car. However, I expected at least 10whp with what I experienced with how the car felt after the tune, but the dyno proved me wrong

Oh yeah, seems there's an issue with launch control. It only works on Map 2, can't be combined with flat-foot shifting for now. I'm sure John is working on that.

Other than that, the 1.14b4 is simply amazing. This is my first Ecutak tune, and I'm happy with it (expect for the glitches)

Just a reminder that JV has a thread in the FI forum for discussions about his FI tunes.

Over a previous version of Visconti's tune? or over stock?

Over stock tune. I have TRD intake, HKS front pipe and Legamax catback and managed to dyno at 172whp & 140wtq (stock tune). Last night I ran 176whp 143wtq with the 1.14b4 tune. I think it could be the crappy pump-gas or my car would need a custom tune.

Oh yeah, the TRD intake was calibrated as a stock intake.

When u guys says datalog what do you mean? Iv been running my tune for a couple of days now should I be doing something other that driving it ?

It's a procedure for when you hook your computer up to your obii port then have the computer monitor all the things that's going on with the car while you drive it. Typical you'd do a pull from a dead stop or a slow roll to red in 2nd or 3rd gear. 3rd is better to see what it's like under load , but due to speed concerns 2nd should do. You then send that file to John to have him look and make sure everything is running safely and properly.

That's interesting. I made 12whp over my stock tune with just an intake on the super old version 1.0 last year. The pump gas version 1.14 feels like my old 1.12 E85 tune...
