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

    There’s 94 octane pump gas 70 miles from me, will try to get some this weekend and do more logs then. No corn at all where I live 😭
  2. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    If timing is horrible on map 1, what can I do to improve that? Fuel is 91 and I added VP octanium booster to 93ish, but even if the booster doesn’t do much you would think I get a real 91 at least šŸ˜‚ Lowering boost on Map 1 —> Map zero šŸ¤¦ā€ā™‚ļø

    Not near my car at the moment, but it’s this parameter that I have to set to 40 right?
  6. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    I did left FF as it was. Will log again with FF at 40. Octane booster’s the only way to achieve 93 ish octane with the crappy fuel in my area, unfortunately no corn juice up here!

    I know that Visconti can do a remote bench unlock with the tool they shipped you. My question is about Eurocharger claiming to unlock 120 ROM through OBD. I call BS on that
  17. 2021 Ecu OBDII unlock???

    Anyone heard about about eurocharger? They claim to unlock through OBDII the 2020 Supra ecu that were locked by the update flash and the 2021... Said they unlocked and flashed directly through OBD a 21 with a march 20 ecu... Thought all updated 20 and 21 had to be bench unlock!?
