Frs vs s2000

What happened to your car? Were you affected by the DI failure?

Completely agree... I feel my comfort behind the wheel of a car doesn't translate at all to my comfort level on a bike. Throttle wuss here too.

At this point I'm thinking I will have to eventually say f*ck this car and sell or f*ck this warranty and flash. I'm honestly on the fence right now.

While I'm not a fan at all of ECUTek's handshake protocol altering, I still believe it's the best available option.

We don't sell ECUTek for the record.

I've been thinking about getting a bike.. would be a small engine 250-500cc. I only want it to ride to work due to my shitty ass parking garage and for fuel economy.

No, but I've ceased and desisted from any track activites (only put in 1 @ Thunderhill) in the FR-S after seeing the SA bulletin. I felt by reading that bulletin they might as well been talking directly to me and describing my usage. I don't even want to risk the nightmare that CSG_Mike and others have gone thru... especially when I have a faster and more fun (IMO) car sitting in the garage begging for seat time. I treat my FR-S like a flippin Prius nowadays and I'm not even getting 50mpg.

I feel like Toyota has shafted their early adopters since the new cars have ZA1JA01C and I can't get it.

I still think the FRS is a better daily but when it comes to track-only or a purpose built race car, the data doesn't lie. I have to choose the S2000.

I went back to the cheapest car I had sitting around. Walls = DGAF anymore

I used my car at the track quite a bit and it's an early car * (May '12 delivery). Fortunate I guess, but no issues yet. I've stopped tracking it but the DI issue was only a minor reason.

Is your belief that ECUTek is the best option available based on evaluation of what Vishnu is doing w/ OpenFlash?

Can you link me if there's any new developments? I'm admittedly a few weeks behind...

I'm comparing @ImperiousRex's turbo BRZ vs a S2k Challenge mod-class S2k, which are near analogous in terms of performance. Some more data points:

- My butt dyno says the BRZ is about 220whp, same as a S2k with TP, but with a slightly fatter powerband.
- Front straight and T9 entry Vmax is identical in both cars (129mph front, 127 T9)
- Both cars are big wing/front lips/splitter cars
- BRZ is faster through T1, 3, 5, 6, 7, and a hair faster through 9
- S2k is faster through T2, 4
- Cars are equal through T8
- Overall, the cars are SO close that I could overlay 3 laps from both cars when looking at data, and you'd think they're the same car.

Data from S2kC mod cars are from various S2ks I've driven over the years at WSIR, as well as data posted/collected.

Stock BRZ vs stock CR (tires/brake compounds equalized, but not size):

- BRZ sees about 122 mph in front straight, 126mph entering T9
- CR sees 128mph in front straight, 127mph entering T9
- Lap times: 1:38.0 BRZ vs 1:34.5 CR
- BRZ corners slower due to less power to the wheels overall, but accelerates faster from T5 to T9, where both cars are both WOT.

Love all the data

Really shows how fast the s2000 is. And that's an NA s2000 vs. turbo BRZ right?

EDIT: Damn I'm driving *slow* at that track. I enter T9 ~40-50 mph slower than you lol I need more track days. Hopefully next month I should be going to both Big Willow & Streets.

I'm not necessarily following the cutting edge of development on this ... but I have looked a little bit at what it offers as far as DI fixes.

http://procedetuning.com/BRZ_FR-S/FA...ash/index.html

They even talk about it in their FAQ's:
Do the Off-the-shelf (OTS) OpenFlash maps incorporate the Direct Injector seal fix?
Yes. All OpenFlash OTS maps are based upon the newest factory software with DI seal fix. So even if you have old software without the fix, flashing your ECU with any of our OTS maps will give you the fix.

The $1M question then becomes ...

Is a flash from this device detectable by the dealership?
Each modified ROM file is based upon the original ROM. In this ROM file, you have all the mapping data and the software ID data. Typically, you will only ever want to modify the mapping data. Which means the software IDs will be untouched and stock-looking upon basic inspection. However, it is possible for the dealership to conduct a more thorough inspection of the ECU code. Which is why we recommend flashing the original ROM file back into the ECU at your own discretion.


All that being said, I'd rather not pay a single cent for something that TOYOTA should be fixing for free! Are you listening TOYOTA?!?

OpenFlash is looking really awesome. Honestly N/A I don't see any point of going Ecutek. But there still is no F/I or e85 with OpenFlash (yet) but I have big hopes for the platform!

@AyJay thanks for posting that info about OpenFlash..

I have big hopes for it to ... eventually, since it's all "open", I'm hoping there will be a pretty extensive library of maps available to those who want to download.
