  1. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Yep E35 would be a good start
  2. Shane's 2024 Toyota GR Supra Build

    I think we limited 6th to 24 psi and it was ok. No idea on the torque numbers.
  3. Shane's 2024 Toyota GR Supra Build

    Yep, the 26 psi map is slipping the trans so be ready for that😂 Taper to 20 seems low for e50+meth idk
  4. Shane's 2024 Toyota GR Supra Build

    32psi? I'd be interested to see that. Kill map on E50+meth is around 26 psi taper to 24psi. It's got a little more in it. @Got_M around 530whp give or take based on 60-130. Fastest stock turbo no nitrous I've tuned.
  5. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    eh 3rd gear or 4th gear is best for evaluation. Can see how map 2 looks and maybe move to map 6. may need a little more E
  6. Official ABSOLUTE ZERO WHITE Supra Club Thread

    Always looks peak in the bright sunlight, the metallic is stunning.
  7. How should the car feel at high speeds? 105+

    Completely stable at 150+ on a track, of course. Alignment is important. Standard tire pressure ~38psi
  8. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    should be easy to get into 8s with the map 6. its around 20-25whp more than map 2
  9. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Was this map 6? log?
  10. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    half a second probably.
  11. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Yep and @Got_M can confirm MHD OTS E40 did ~8.7 right? Pretty impressive for the jb4 to match that in some cars. Now JB4 + MHD backend flash on E50+meth in mid 7s lol I've got one customer hitting low 8s on JB4+E45 but its thrown a couple codes here and there (his map) so I don't push it...
  12. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Mid 8s at best with the fp upgrade and E40 You can run a bit more E, just watch trims and try to keep under 45. something like this would be an appropriate map 6 for no fp-upgrade. map6_15 map6_20 map6_25 map6_30 map6_35 map6_40 map6_45 map6_50...
  13. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Under advanced, firmware, platform 158 on the app
  14. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    looks pretty good, I recommend updating to V28+ firmware, but this is a good E blend for map 2. You will need a bit more ethanol to run anything higher
  15. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Try 2 gallons E85 with map 2. E25 max without FP upgrade, E40 with.
  16. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Exactly what @Got_M said. Map 2 is pretty solid but a little octane deficient. like 2 gal of E would help it make more power. If its hot out, I'd probably stick to map 1
  17. Anyone mess around with 60-130 times?

    connect app also says how many gallons are in the tank
  18. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    looks like typical MT fun lol, would need the datazap but I can tell your FF needs to come down a good bit. I usually prefer additive mode for MTs anyway on V28 or newer firmware.
  19. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    It will target 26psi but really it runs more like 24-25. You can start on map 4 with anywhere E30-40 with FOL at 60. If it all looks good you can try map 5
  20. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    eh not really just keep an eye on trims and timing to keep it dialed in
