  1. MHD to release Map Switching + Antilag + Flex Fuel update for Supra in 2022

    100% agreed on your last comment. The Reflex is a great box. It's always wiring or wrong firmware!
  2. State Referee

    Fragile man tears.
  3. MHD to release Map Switching + Antilag + Flex Fuel update for Supra in 2022

    Don't get me wrong, a PnP harness is much easier to install. But I personally find that to be relative. The Motiv-provided harness isn't exactly difficult: find a wire, tap a wire. That's not rocket science. It takes an hour. Sadly, their design just doesn't work very well. It's my personal...
  4. MHD to release Map Switching + Antilag + Flex Fuel update for Supra in 2022

    The big issue is that the the Motiv-provided harness is junk. It's honestly terrible. So many weird connectivity issues. They all went away when we swapped to a PnP harness from Tensility. The controller itself is good, but nobody should the Motiv-provided harness even if it's an easy install...
  5. Burger Tuning BMS Elite BMW/Supra B58TU Charge Pipe Blow-Off Valve (BOV) Kit

    The Vargas adapter connects to a port on the front of the manifold. See here for the issue(s).
  6. Burger Tuning BMS Elite BMW/Supra B58TU Charge Pipe Blow-Off Valve (BOV) Kit

    And now we see the vacuum line for the BOV runs towards the firewall, which tacitly confirms my theory they're tapping the brake booster line as a vac reference. It's one of the few places on the car that actually does that function.
  7. M competition wheels on Supra?

    Think of all the money I could've made! Oh well. Wish they'd sell their bracket adapters as a standalone kit so I could go fish on LKQ or Facebook.
  8. Best exhaust, figment, performance, price

    No. 100% no. Exhaust "backpressure" is a meme-level myth. You want ZERO backpressure on a turbo. Hell, if we could make the exhaust a massive f'ing negative pressure vacuum it would be even better for a turbo.
  9. Burger Tuning BMS Elite BMW/Supra B58TU Charge Pipe Blow-Off Valve (BOV) Kit

    I know what fitting you're talking about, and I was always under the impression that this barb on the front of the manifold doesn't actually provide vacuum. If you look at MAP from the car, the manifold doesn't really hold strong vacuum like other cars d/t BMW valvetronic. I don't believe that...
  10. Burger Tuning BMS Elite BMW/Supra B58TU Charge Pipe Blow-Off Valve (BOV) Kit

    You wouldn't need to touch the bolt if I'm right. It would just snap onto the breather as a MITM thing. //edit: Judging by the construction of the 2pc brake booster hose, I think you could also install this thing between the two hose halves. I believe the male end of the fitting on 44763A in...
  11. Burger Tuning BMS Elite BMW/Supra B58TU Charge Pipe Blow-Off Valve (BOV) Kit

    Until proven otherwise, I'm going to assume this uses the BMS N54 vacuum adapter (or something like it) to provide a vacuum reference. I believe it sits on the engine block end of the brake booster hose. The hose runs from an air valve that plugs into the block up to the master cylinder on the...
  12. iDrive Screen Constantly Rebooting

    Bizarre electrical gremlins on the Supra are usually the result of a weak or dying battery. Charge it to full on a battery tender before drawing any conclusions.
  13. What mods or choices do you regret?

    My Twisted Tuning transmission mounts. They're fantastic if you spend your life in sport mode above 3K RPM, but they're just miserable for daily driving. I'm taking them out and will be trying a softer 70A bushing from PowerFlex. They're still firmer than stock, but much softer than the TT...
  14. Good tires that’ll hook 700WHP.

    I've driven them in the rain three times. They suck in standing water. Very unnerving, as they cannot evacuate water very fast. But they're okay in wet roads if you don't drive like a dink. Overall I just take it easy, and it's been okay. I don't think they'd do well in downpour conditions. But...
  15. Armaspeed or CTS intake

    The trick to removing the breather is to not bother pulling it with your hands. Squish the clip, then use the twisting leverage of a thin screwdriver inserted into the seam to pop it free.
  16. GR Supra 101: Routes to big power

    You don't make more power without adding boost or adding fuel octane. This is not the whole story, but it's 9/10ths of the law for your question.
  17. Weird whistling noise on idle

    It's probably the electric water pump. At any rate, this is perfectly normal.
  18. Pure trans broken?

    We can't help you. This is between you and Pure.
  19. Turbo guard vs filter for 6870

    How in the world is that a 20 micron filter when I can drive a truck through the gaps in the mesh? 20 microns is smaller than a white blood cell.
  20. Full e85?

    It's free EGT reduction. /shrug
