  1. Seat warmers, how to tell they're off?

    @BMWAF Alcantra seats (even base models) in 3.0L have heat in USA. The 2.0L's do not and have the seat heater buttons blanked out, and the seats are manual adjustment. Examples...
  2. Retro-fitting a heated steering wheel to the Supra

    Very subjective. I have the steering wheel the OP swapped to in my G20 330i and I personally prefer the OEM wheel in my Supra over it.
  3. How common is an issue like this that requires so much excess disassembly to replace a simple part?

    Modern BMW's are pretty reliable. My supra has been by far the most reliable car I have ever tracked. It has 60+ track days, 40 of which with over 500whp. 2300 laps and 51 hours of track usage. No issues.
  4. Lightweight battery alternative

    They already do. H6: https://powertexbatteries.com/products/powertex-batteries-bci-group-48-lithium-iron-phosphate-lifepo4-automotive-battery?rq=yr_2016~mk_volkswagen~md_touareg
  5. How common is an issue like this that requires so much excess disassembly to replace a simple part?

    I love when people don't reference service manuals when working on a car then blame the car for confusing them.
  6. Oil Pressure with Modified Supras

    Ah, I was looking for cracks.
  7. Oil Pressure with Modified Supras

    Nice! Am I blind though, I don't see any damage to that pump?
  8. What's causing my tune to break up in 5th gear?

    The only counter I have to that is that your boost target is ALSO changing. If it was just boost going over target, I would say his hypothesis could be correct. Also, the logged oil pressure is also not changing when the exhaust cam deviates from target.
  9. What's causing my tune to break up in 5th gear?

    Yea I called out the exhaust cam deviation in the log before. HPFP is driven off the cam, which can be affected by a stiffer/upgraded HPFP. Oil pressure controls the VANOS adjustment. The measurement is angle.
  10. Door panel gap issue

    Shhh, he's well educated.
  11. Race Tracking Your Supra - Information exchange

    Haha I think we all have these stories. My moment the car tried to just shoot me straight off the track on turn 1 at Lime Rock. I was chasing a TCR car and was gaining on him every lap so I was pushing a bit hard. The super interesting thing is that it opened up the diff as well, you can see in...
  12. What's causing my tune to break up in 5th gear?

    I think I know what might be happening here. I found an issue awhile back with the Max Boost Reading table. If you don't raise it, boost can spiral out of control and shoots for the moon. I noticed that it was easily provoked when I went to a track at higher elevation (Pocono) as well. That is...
  13. What's causing my tune to break up in 5th gear?

    Yea something is def up with this tune. As far as flex and boost. It depends on the tuner and the turbo. With a turbo that flows more, you should def target more boost with higher ethanol content.
  14. What's causing my tune to break up in 5th gear?

    That is one aggressive tune. Timing isn't happy. Lot's of boost. Is the issue happening on the shift into 5th? In the first log, the HPFP maxes out and AFR is a bit lean at the shift into 5th. Also your vanos target/actual is way off.
  15. Ambient Temperature Sensor Issue

    It's above the brake duct on the right side (passenger side for USA)
  16. 2025 Supra 3.0 Base (Automatic vs Manual) - Canadian Spec

    Newb that doesn't own a Supra: "Guys, I have this list of things that I think are different between AT and MT versions of this car I want to buy, can you check my list and let me know if it is accurate?" People that have owned, worked on, modified, raced, and reprogrammed MK5 Supras for years...
  17. 2025 Supra 3.0 Base (Automatic vs Manual) - Canadian Spec

    By listening to the people (Ironically, the people you asked) that are more knowledgeable about the cars they own and work on, in contrast to a car you do not own yet. Are you actually reading back to yourself the replies you are writing?
  18. 2025 Supra 3.0 Base (Automatic vs Manual) - Canadian Spec

    At this point, I'm not sure what to say. I showed you the service manual about the covers. I have told you I have taken off the covers before. I told you the website is incorrect on the details. 2024 vs 2025 is the same as far as the bits we are discussing. Again. I have worked on these cars. I...
  19. 2025 Supra 3.0 Base (Automatic vs Manual) - Canadian Spec

    Same car. Has ABS, has 4 link on all models, has hollow sway bars. Even the 2.0 is the same as far as those items. You are incorrect. The 2025 tab on the website is incorrect. Me answering your questions is annoying? You must be a hit at parties. Again, why ask questions if you are just going...
