SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

[blazzzed1]

Just installed jb4 and new to the platform only have a cai atm. This was the best looking pull out of the ones i did on map 1 with a mt 93 octane in MD. Any info would be great https://datazap.me/u/blazzzed1/log-1746057235?log=2&data=1-4-5

thanks in advance!

Boost and timing look great. What is map 1 targeting?

Hey all, throwing my hat in the mix here. 2022 AT, Catted DP and Intake. Took a Map 1 log to start out and would appreciate anyone taking a look at it before I move on to Map 2, thanks.

Need to do a 4th gear only pull from 2500-6500. Looks like traction kicked in a bit, otherwise good. @ColonelAdama Boost levels between this run and the other map 1 recently are way off. Different jb4 versions maybe?

Thanks for looking. This was a third gear run, latest B58 gen 2 stable firmware, one click traction mode. I didn't feel or see it kick in.

Im not sure what you mean by targeting beside most hp while not running too rich/lean. I'm trying to see if i can try map 2. I've read all the info on 1st page and still lost... might as well be a different language to me

Hey ColonelAdama, I’m new here. I’d appreciate if you could take a look at my log. The log has a pull from 2nd to 3rd. Then another pull starting from 3rd.

From what I see, everything looks ok. There is some slight throttle closures but I can’t say I can feel them to be honest. Drivability seems similar to stock. TC was on (forgot to turn it off before I started the log).

GR Supra Manual
- Kenji 200 cell DP
- 92 Octane
- JB4 MAP 1

Looks pretty good but try with FF at 40 next, throttle cutting in too much

Looks good, near the limit of the octane so Map 2 will probably just have more timing corrections. You can try but I suspect the car wont be happy with it.

With MT, recommend V28 firmware or newer. Try again with FF around 30 on Map 1

Looks alright, timing is a bit rough. Can you do a Map 2 pull for comparison? Some cars are happier on additive.

I think you might be right. Still learning how to read this all but this was my one run on Map 2 last night. Do you recommend a splash of E85 or am I skipping steps here?

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

Wondering what you use to truncate data in the log files. I tried opening in ss. Looked for the timestamps to delete rows and resaved as a csv file but when I opened it back up in the jb4 log viewer there was a lot of empty space and some of the data options were not smooth anymore. Is there some meta data that the app uses that needs to be updated (just thought if that so I need to check)?
