SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

[supra_hopeful]

yep, try 2 gal E85 in the tank if you wanna run map 2

Alright, I have two new logs now with 2 gal E85. Timing looks like it cleaned up a lot, still getting a bit of throttle closure ~3200 rpm. I'm also seeing 4-5 psi lower boost readings vs some of the other posters' recent logs. Is that a catted vs catless difference, or do you think there could be something else there? Another member also mentioned that.

Map 2 looks good, you can run it.

boost changes based on IATs(and a to a lesser extent some other factors like DA) so no point in really comparing to anyone else

Howdy, I’m having some issues under wot. I think I’m having throttle cuts. Mods are catless dp, hks exhaust, and awe intake. And with 3 gallons of e85. Log is from map 2. Thanks

V24 or newer firmware, use the duty bias settings provided in the first post of this thread with FF at 35

Okay sorry I forgot to mention I’m automatic idk if that matters but yeah. So set the firmware to beta? And then I’m confused on how to change ff

No it does not matter on your jb4 app go to settings and click on advanced. you should see the section for frimware and click that. you should be able to browse frimware and look up b58/48. it has to be the 158 one. then download the stable version of the frimware then flash it (should take about 3 mins)

Dang Looks like previous owner was on b58 gen 1 firmware. How do I change the duty bias ?

in the same section as settings you should see "user adjustments" you will have your duty bias in there. since he adama asked you to set ff at 35 it should be in the options tab once you click user adjustment. Just make sure that you save any changes that you make, you will know if it was successful if the car does 2 signal light clicks

Okay I just made all the changes to duty bias and ff. Map 2 and took a log. Still seems to be cutting throttle as around 4500 rpm. https://datazap.me/u/austin101400/log-1746834174?log=0&data=1-4

I'm going to be honest I have NO idea what I'm looking at, did a 3rd gear pull from 2500rpm to 5ish/6ishk rpm. I have no idea what to change or do. this was Map 2, was getting some pretty bad throttle hesitation, so I switched to map1 and it's been smooth. but I want to get more power out of it. please advise

Thanks for all the help so far. I got to do some logging on Map 4 yesterday, still on the same tank of ~E20. After the first two pulls, I changed the duty bias settings to the aftermarket dp settings in your first post that I had initially overlooked. Throttle seemed mostly good after the change except for one ugly pull, not sure what happened there. Anything to look out for here?

Would anyone be able to check over this log and let me know how it looks?

Only relevant mod is an MST V2 Intake and xHP Stage 2 transmission tune. Stock DP, stock exhaust.

Map 6 by Jesse (Did it 8 months ago, so I think it's too late to go back to him for revisions?)

https://datazap.me/u/jmikes99/jmikes99?log=0&data=1-4 (Last quarter or so is with JB4 disabled. 85 degrees ambient and high humidity, and at sea level.)
Dragy pics from a couple weeks ago (same settings, but ~15 degrees cooler out at the time. I did not have xHP at the time though.)

Thanks!

Looks pretty good, keep an eye on trims. I'd probably IAT spoof around 100 to keep them more consistent

Looks fine to me. I personally prefer an additive map like this on E20

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​	1.5​	2​	2.5​	3.5​	4​	4.5​	5​	5.5​	5.5​	5​	4​
