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

    @djf It's fine. Stick to E25 without FP upgrade (roughly 1:4), E40 with FP upgrade (roughly 1:2 at FOL 60) Use a calculator like this: https://morepowertuning.com/pages/emix?srsltid=AfmBOoqmQht5WDpxATypuYsMgHN23Ev7lNVH9XvQcZEH6MA8_yhLJyIn and verify your trims stay under 45.
  2. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Send me a PM if you want to get the stuttering worked out. Can take a few revisions on MTs. Solid time though!
  3. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Map 1 looks pretty solid and only needs a few adjustments. For Map 2, I would keep dropping the duties under 5k until you stop getting those throttle closures. Try in increments of 5.
  4. JB4/MHD BACKEND FLASH

    Probably less gains to be had on 93 only, so enjoy what ya got!
  5. JB4/MHD BACKEND FLASH

    Doesn't hurt to try. Can always flash back OTS if not better. PM me if interested. Won't be able to push 7s without meth though.
  6. JB4/MHD BACKEND FLASH

    JB4 + MHD backend flash did, yes. Just for anyone considering selling their JB4 after unlock ? Basically the ecu flash gives the JB4 the proper fueling it needed all along, and let's it continue to manage boost control.
  7. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Sub 8 coming soon! Really pushing the limits of the stock turbo here at 24-25psi on the BEF with meth. @Got_M , What was the 60-130 on MHD E40 OTS?
  8. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Definitely much better. Try updating to firmware V28 and do one more pull before we adjust anything further. V28 has to be tuned differently than V27, so no point in doing it twice
  9. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Yessir. A properly wastegate-dialed JB4 map is even smoother than map 0 with a dp. I'll be away from my PC for a few days, so I'll have to catch up on reviews. But keep playing around with the FF setting. Drop until throttle is generally >90 during the pull. Read about duty bias in the first...
  10. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Nothing wrong with the throttle, it's just because of your downpipe. Car is overboosting and the throttle is preventing the excess from entering the cylinders. It's still running your wastegate as if there is the stock dp restriction. So you need to reduce FF(feed forward) until throttle...
  11. Installed mst v2 intake no turbo noises?

    u aren't getting into the pedal enough, engine needs to be under load(driving) to make boosty noises
  12. The dang seat noise…

    My MK7 is less creaky than the Supra ?
  13. Selling my 23' MT

    My first kid is due next week and Supra is staying... for now ?
  14. OBDEleven now supports Supras, does anyone have one to see if they have any features that Bimmercode does not?

    i use OBDEleven for my GTI and it a nice app but yeah, you'll end up spending 10-20 bucks on credits to do the coding "apps" if you don't hard code it yourself. I wonder what options it will have compared to Bimmercode.
  15. What Intake Should I purchase

    Looks great, I may do the same. Kept the stock intake, put in a Dinan filter. Actually did go from being silent to slight turbo noise. Probably will do the intake muffler delete too and call it a day.
  16. What did you do to your Supra today?

    Well you accuse me of shilling any time my thread comes up, so... Find me one example of someone saying a JB4 is better than unlock ?
  17. What did you do to your Supra today?

    No one is saying they are better at all lol.
  18. Catted downpipe and opf delete CEL

    Your armytrix has a cat simulator. You shouldn't even get a CEL. I haven't and I'm catless. My other car is a 200 cell and it didn't even need a simulator, just a spacer. No CEL either. Good that you did go for that DP because that is literally the only way to prevent CEL on locked dme.
  19. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Great example, I'll add to the first post.
  20. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    The base timing(and boost)will fluctuate based on IATs. What you are looking for is any drop from ign1-6 climbing to redline. No timing corrections = all cylinders converge and climb linearly towards redline 1-2 cylinders dropping <3 degrees is typically OK, just means you're reaching the limit...
