  1. Another Vendor Fails At Assisting with Mother Russia Femto

    I wouldnt be surprised if they are using a a timing or power related attack on the physical hardware. There are attacks where during startup of a microcontroller its vulnerable to attacks if you can freeze code execution. There are other attacks where you can cause odd behaviours by drooping...
  2. Issues on test drive before ordering - are they common?

    The wheel isnt great, ill be upgrading mine to a alcantara as well. The alignment from the factory seems to be a coin toss. Mine is bad, its very twitchy even mid corner and neutral. It has nothing to do with the car itself. If you search around here for alignments a few people have posted...
  3. We need to boycott Supra tax

    There were ~7k Supras sold last year. Many of them will keep the car bone stock or near stock. I’m sure there is some expensive car == higher prices because owner can afford it going on. But when you don’t have high volume in sales you raise the price to make it worth actually designing and...

  5. How Much Money in Mods?

    Im at $15k with like 700 miles on it lmao. Bought absoutely everything I wanted for it the day I brought it home minus a turbo, intake manifold, injectors, trans, etc. Will wait for next winter to do the big power stuff most likely.
  6. Wireless Carplay - Low Volume Compared to XM

    XM has some of the worst sound quality of all options on the market. XM has two satellites that only have 4mhz of bandwidth for ALL channels. This means each channel only has 64kbit/s available. They use a slightly different version of the ACC codec, which is roughly the same as ~100kbit/s from...
  7. Would You Drive An EV Tesla?

    That assumes you WANT to stop somewhere over night, and also assumes you have a hotel you want to stay at that also has a charger near by. People take 4+ hour road trips all the time. Adding extra hours for most people is not reasonable just to charge. We all have one resource we dont get back...
  8. Would You Drive An EV Tesla?

    Taking a proper road trip in a Tesla or any EV is a giant PITA. The range just simply is not long enough and you are constantly worried about getting to the next charging station and then when you get there its at minimum 20 minutes if there isnt a line of cars waiting before you, if there is...
  9. Traction Concerns

    Michelin and Dunlop make some of the worst tires for performance imo. I’ve never sent a bike into the dirt more then on a set of either. Personally I put a set of Falken rt660s on, I think they are a really good balance between grip, road noise, durability, and performance. They are also “ok”...
  10. PSA: Are you about to buy a new turbo? You should wait.

  11. Visconti DME with production date after 6/2020 cloning

    Build something with motec and you'll feel that $5k is a bargain lol. People will spend $4k-5k on a set of wheels and tires, body kits, carbon fiber, etc. without a care in the world. Then complain about spending the same money on the thing that makes the car actually move. Yeah its a good...
  12. Visconti DME with production date after 6/2020 cloning

    Yes it’s completely legit. My 2022 is tuned on a cloned ECU, running flex fuel.
  13. Experiencing knock on acceleration (BootMod3). Help analyzing graph.

    Here’s some resources for you if you want to understand a bit more about knock detection and sensors. https://tunertools.com/pages/knock-detection These sensors are typically just microphones that filter out a bunch of noise and try to listen for engine knock. The filtering isn’t perfect...
  14. 275F/295R on stock wheels

    You can do anything. Doesn’t mean you should. You are changing the shape of the tire surface that touches the ground, the flexibility of the sidewall, and the dynamics of how the suspension interacts with the tires. You will change how the car feels and drives. The car is going to feel softer...
  15. 275F/295R on stock wheels

    https://www.supramkv.com/threads/trying-to-fit-275-35-r19-on-oem-front-and-rear-wheels-on-2021-supra.12191/#post-176432 You cant just slap larger tires on a rim. Tires are specd for specific width wheels, going out side of that changes the entire dynamic that tire provides. The car will not...
  16. PSA: Are you about to buy a new turbo? You should wait.

    Want to be clear although I am capable of tuning and have worked with several other platforms, I have not even touched this platform from a tuning standpoint. Im just repeating what I have asked the larger names here. From what I have read and heard you will start to have issues around 500-600hp...
  17. PSA: Are you about to buy a new turbo? You should wait.

    Yeah, honestly modifying our exhausts to hold a high flow cat and extending the o2 wires may resolve that but modern ECUs are really really sensitive now so it may not even be an option. Thats also a shit ton of work lol. I've pretty much convinced myself that ill be alright with swapping the...
  18. PSA: Are you about to buy a new turbo? You should wait.

    Even the GESI cats are a problem from everyone that I have spoke with. The link I posted is an Active Autowerks cat that uses a GESI. Its generally considered one of the best on the market and it still had that problem. They are only rated for 1500 degrees and turbo cars will sit right around...
  19. PSA: Are you about to buy a new turbo? You should wait.

    Its not gonna work well if at all. I've spoke with several tuners and read a ton of posts on people trying to run catted with a larger turbo and the cats just cannot handle the heat. https://www.supramkv.com/threads/catted-vs-catless-my-story-with-data-to-share.6116/ You will end up melting...
