Default 2021 Supra first log - 10-21-2021, 04:21 PM

Just got my JB4 today, this is the first log for it.
Supra is Stock with just a muffler delete, running on 91 Octane Map 2.
Never Data logged before so let me know if this is good enough or if I need to redo it.

Other than starting in 2nd and some wheel spin, the log looks pretty normal.

Ended up trying Map 3 with E40ish (first time mixing fuel and no Ethanol sensor, just ethanol test kit.) Did multiple runs from different gears and speeds.
First 2 pulls, car felt a little jittery but i think it was because it was losing traction once boost hit.
4th Gear pull felt good and smooth.
Dig one was just for fun and spun wheels quite a bit at first.
Did another 3rd gear pull again and this one felt good and smooth unlike the first couple 3rd gear pulls.(maybe just needed to warm up the tires )
Overall pretty fun and happy with it, but just want a professional's opinion.
Thanks again for the help!

Log looks pretty normal, a few minor timing corrections up top but not bad.

Hey so wanted to push more power out of the Supra and tried Map 5 on E50.
Here are the logs, tried in different modes as on traction mode it killed boost in 5th gear but then noticed that in all of them the throttle is choppy.
What should I do? or is this normal.
Thanks again for all the feedback so far!

WGDC is maxing out on your Map 3 log. When you get logs, always have traction off. Map 5 appears to run better, but please upload a map 5 log with traction off. Thanks!

Ahhh okay, got it.
Here's another log on map 5, E50, and Traction off on both pulls. First pull forgot to put it in sport mode (idk if it matters), Second pull was with Sport mode on.
Also is there anywhere where I can learn how to read the logs from JB4 more in depth. I know the very basic things but would like to learn more so I can look over at my logs over time with out bothering you guys with every little change.
Anyways Thanks Again! You guys are very helpful.
P.S. just noticed I messed up the name on the last log "Map3, E50, Everything off" it's actually map 5 as well, not map3 like the name suggest, my mistake.

Logging Parameters and their Meaning - N54Tech.com - International Turbo Racing Discussion This link will help teach you on the JB4 logging parameters. Log looks to be running good, WGDC is getting very high. Would keep an eye on it.
