  2. JB4 Maps on 93 Octane

    try something like this. It should be a little peppier than Map 2. map6_15 map6_20 map6_25 map6_30 map6_35 map6_40 map6_45 map6_50 map6_55 map6_60 map6_65 map6_70 1.0 1.5 2.0 2.5 3.5 4.0 4.5 5.0 5.0 4.5 3.5 3.0 if it rounds any of those targets by a tenth, don't worry about it. JB4 has...
  3. JB4 Maps on 93 Octane

    In my opinion, you just need to drop duty bias at 5k by a bit until throttle closures stop dropping below ~80. Try something like 44 or 45 instead of the current 48. Otherwise it is not far off from being perfect. @i3igpete, I don't think any drop in boost targets is needed. If anything, I...
  4. JB4 Maps on 93 Octane

    0-60 runs aren't any good for reviewing logs. Need a 3rd or 4th gear pull from 2500 to redline, and ideally a shift into the next gear before letting off. You can't accurately tune your FF curve without looking at the entire RPM range while you have full traction and no boost by gear (ie. 3rd...
  5. Bimmer Code Sport Plus mode

    I coded Sport Plus into my MT. I took JB4 datalog in both the regular sport individual and then sport plus. absolutely no difference in the log, so don't expect power difference. I didn't notice any sound or burble difference. Sport plus does have slightly sharper pedal response though. no...
  6. JB4 Maps on 93 Octane

    Default wastegate position is supposedly a "lag-fix" but even BMS doesn't mention it much because it hardly does anything. Default is 0. I have tried up to 50-60. I've heard after that, you can get a CEL. It was more made for N54,N55 cars that have pneumatic wastegates. Not electric like b58...

    Good 93, log looks great.
  8. Official ABSOLUTE ZERO WHITE Supra Club Thread

    Absolute Zero appreciation post. Great lighting really takes the pearl to the next level.
  9. JB4 Maps on 93 Octane

    Everything would be the same. FF is saved per map though. Duty bias saves for all maps Map 6 is just boost targets, so the equivalent of Map 2 would just be ~4 psi with some taper on both ends of the rev-range.
  10. JB4 Maps on 93 Octane

    Yeah looks to be pretty clean, but will need a better log to know for sure. 2500-redline in 3rd or 4th. traction needed

    Try this with Map 2: duty_15 duty_20 duty_25 duty_30 duty_35 duty_40 duty_45 duty_50 duty_55 duty_60 duty_65 duty_70 32 32 32 32 35 36 39 48 55 57 62 62
  12. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    mods, fuel? need a log 2500 to redline in 3rd gear or higher
  13. JB4 Maps on 93 Octane

    Yes, Duty bias applies to all maps. All the fuel stuff is 0, doesn't apply to b58. all others settings can stay as default.
  14. JB4 Maps on 93 Octane

    These duty bias a good starting point for a high-flow catted DP on Map 1 or Map 2: duty_15 duty_20 duty_25 duty_30 duty_35 duty_40 duty_45 duty_50 duty_55 duty_60 duty_65 duty_70 32 32 32 32 35 36 39 48 55 57 62 62 Try this with Map 2 and...
  15. Tried out map 4 with the jb4 on e30, here are the logs…

    Just looks like too much E. I think these winter E85 blends are higher ethanol. because I've seen a lot of people struggle to run E30 recently. Please dilute with gas and post another log, but this time from 2500 to redline in 3rd or 4th gear. It's probably better to target E15-E20 for now. <2 gal

    like you said above its probably intentional in the BEF, you could always ask Terry
  17. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    I don't know if BEF vs stock map timing is a fair comparison. Wouldn't surprise me if the BEF dialed it down a little to run higher boost. For you, 15 at redline may be unrealistic, and that's fine because you're making way more power lol. follows what you said about the ign1 timing above. he...
  18. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Here's a great example of a Map 4 that is dialed in nicely: https://datazap.me/u/coloneladama/log-1708732537?log=0&data=1-3-4-9-11-14-18-25-26-27-28 @Foxrider0314 's car getting the most out of Map 4 after a few duty bias/FF revisions. see all 6 cyl ign timing converged and climbing to 15...
  19. Can someone review these jb4 map 5 logs for me

    Yeah I've never used avg_ign. Even if it is meaningful, you can only see timing separation when you graph ign1-6.
