  1. A91 & Recent 2021 Impossible to Tune / ECU manufactured after 2020/6 is locked? [WARNING: NO POLITICS]

    nothing is ā€™uncrackableā€™. if someone wants to get into the ecu, theyā€™ll find a way. give this ecu to samy kamkar (famous security researcher), and i bet heā€™ll find a way in.
  2. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    Just setting realistic expectations based on what we know so far. Import? Canā€™t import these to the US and still be street legal.
  3. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    Anyone disappointed that the GR Corolla will only be half as good as the GR Yaris just based on weight alone? Itā€™s safe to assume power output will be the same at about 260HP. The GR Yaris is 2,8xx lbs. The Corolla hatchback is 3,0xx lbs. Even if the Gr Corolla doesnā€™t gain any weight, which I...

    The circuit pack has stickier tires? Do you know which tires both models have?
  5. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    Crazy how much a difference front and rear LSDs can make. I think Iā€™ll only buy the Corolla if it also comes with the Circuit Pack.
  6. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    Having physical access to the ECU will greatly increase the attack surface. I think itā€™s just a matter of demand and willingness for someone to break in.
  7. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    I was implying it probably won't be as locked due to it being a Japanese branded ECU. The ECUs are usually just made from an OEM supplier. Probably Denso? I don't think Toyota has much to say in terms of security of the ECU. The Supra is just using a BMW ECU as far as I can tell. Most Euro ECUs...
  8. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    I saw a few tuned GR Yaris videos, so I assume tuning options are available already.
  9. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    Pretty certain it'll run a more traditional Toyota ECU and not BMW.
  10. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    What are the tuning options for the GR Yaris? Ecutek?
  11. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    12s on an essentially stock car? hmm
  12. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    Just lowering my expectations so I'm not disappointed when the car actually does come out lol.
  13. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    I may be reading a little too much into this but from Toyota's page: I completely expect the US GR Corolla to receive the same engine and some kind of AWD system, and stiffer suspension. I don't expect the dual LSD and maybe it won't have the advanced 3 modes either. I can see this being...
  14. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    I completely expect the GR Corolla to be about 200lbs more than the GR Yaris. Even if they brought all the hardware from the GR Yaris, it would still be inferior due to the weight increase. I don't see Toyota using any exotic materials to reduce the weight of the current Corolla.
  15. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    I don't see Toyota adding a manual handbrake just for the GR Corolla when all the other Corolla trims have an electronic handbrake. The Civic Type R doesn't get a manual handbrake just like the other Civic trims. I really can't see Toyota US giving the GR Corolla all the GR Yaris hardware, but...
  16. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    So GR Yaris is built to meet WRC production requirements. Assuming Toyota isnā€™t going to be campaigning the Corolla in WRC, I donā€™t think the GR Corolla will be as hardcore as the Yaris. Probably wonā€™t get the dual LSD and weigh 200-300lbs more. Just my predictions. If thatā€™s the case, Iā€™m...
  17. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    @Galerion, I also have an FK8 Type R and agree pushing it over 140mph, the car is still very stable. On my previous 2015 WRX, the car would get unsettled as soon as you hit the brakes. How would you compare the GR 1.6T engine with the FK8 engine? I don't anticipate the GR Yaris engine to be as...
  18. Updated GR Yaris with Automatic debuts at Tokyo Auto Salon

    i think the clutch has a torque multiplier, so they can call it 4wd instead of AWD.
