  1. Auto Supra - First to Second Gear Jerk/Hesitate?

    Thank you for your reply! I'm still running the 1.3 version - I can try to update to 1.4. I do not have XHP - however, I'm wondering too if I should buy the XHP Trans tune package - this might let me be able to read any error codes from the Trans ECU...
  2. Auto Supra - First to Second Gear Jerk/Hesitate?

    Mine happens with VSC/TC off and in low throttle, parking lot speeds too....
  3. Auto Supra - First to Second Gear Jerk/Hesitate?

    Nope, no drag racing at all and when I do go fast, its taking off from a roll at the stop light then punching it in manual mode.
  4. Auto Supra - First to Second Gear Jerk/Hesitate?

    I think this issue I am having is God telling me to upgrade the trans, driveshaft and axles....
  5. Ecutek tune causing OBDII emissions to fail

    Exactly why I kept my oem downpipe tucked away safely.
  6. Auto Supra - First to Second Gear Jerk/Hesitate?

    I would agree with you, but the car has a flex fuel kit from BM3 which takes into consideration the ethanol level....and it was just fine before hand :)
  7. Auto Supra - First to Second Gear Jerk/Hesitate?

    I switched to the stock map via BM3 multimap and it does the same thing. Its always at low throttle between the 1-2 shift regardless. Starting in second gear the car holds power no problem and there is no slippage detected at all. Besides that hiccup between 1-2 the car drives just fine. No...
  8. Auto Supra - First to Second Gear Jerk/Hesitate?

    Here's a weird one for you guys: 21 Supra I owned since brand new with 2,600 miles on it (yes, two thousand six hundred) BM3 Flex Fuel Sensor Titan Catless Downpipe Bm3 Stage 2 MultiMap Tune Car is reporting about E51 in the tank. Transmission is stock without any type of tune on it. While...
  9. 2021 Supra - Advan GT - KW Coils

    Looks clean lowered with no spoiler!
  10. Slicks and wet don't mix, anyway, is this a total?

    Sorry this happened, glad you are ok and nobody else was hurt (well minus your pride) Don't beat yourself up over it, when I was in my 20's I was hot dogging my GTO while on snow tires and car got sideways coming off the expressway and the car kissed the guardrail. It was a total, but the...
  11. Missing / worn "P" on the shift lever.

    Thats interesting - I have never tried that.
  12. Opinions on Tune, Limited to 91 Octane Fuel.

    You're in California - Don't touch your ECU/DME. During emissions testing the state verifies the checksum and even if you return it back to stock you might not be able to pass unless you take the car to your lovely Toyota dealer and have the car completely flashed back to stock. Do your JB4 so...
  13. Is a 2024/2025 Supra a good choice for a daily driver?

    I would say no. Get the IS500/M3/M340i if you want a great daily with usability that has some fun to it. For what its worth, I've owned my IS-F for 16 years now since new and its been the best car that I have ever owned.
  14. ADDITIONAL SUB AMP CONNECTION

    Usually the Auto On wire is just a relay that will tell the Amp to power up - you could use anything that is powered up when the car is on - with the caveat that the car will stay powered up 7 minutes (i think) after you leave/lock it - unless you turn off the system by holding the volume know...
  15. Wheel Bearing Concern?

    Well, I can tell you from experience that I had a bad (old heat cycled PS4S) tire that sounded exactly like a wheel bearing on the front of my daily driver. I replaced both front wheel bearings and noise was still there - then replaced the tires and it went away. The tires looked fine...
  16. Wheel Bearing Concern?

    Brake pads could be dragging too. Any noise while driving, or noise increase/decrease while turning?

  18. Toyota - Supra Sales for 2023-24

    Yes, interest rates are high, as well as people are being laid off left and right. This seriously reminds me of 2008. It is taking folks six months on average to find a new position and when they are being offered a position is 20-30k less than they were making. (these are college educated...
