Just want to comment and say this is more information than I've ever seen explained on the Jb4 forums. Thank you for this.

This is so much better than "try a log in map 6" or their really short one line answers.

Great video

Thanks for this vid gained a slightly better understanding of what the hell I was looking at 😅

Great video I have the new 3.0 supra and I'm using jb4 also but the afr isn't like anything I've seen it stays at 14.7 throughout the log the tuner said it's a BMW thing it cuts throttle and uses electronic everything to control boost and afr.. I'm still learning everything on it.. it's completely different from my 650whp sti

[SparkyWrench]

Bro, this explains so much! Now can you go into trims, ign timing, and boost?

[chrischarles]

Good video. Id like a more in depth and test video.

Im having some issues with my 22 wrx. Not sure if it's the cvt or the jb4 tune.. PLEASE HELP lol

[spookholidae]

Thanks for da video. I made a couple mistakes...i started in 4th gear and didn't shift manually so it shifted at 6100 instead of 6500 redline. But my boost is nowhere near as steady as yours...it jumps up n down...BMS said it all looks good with no explanation...but the boost is definitely weird cuz on stock map its low but steady. Thanks in advance for any insight.

Thank you, had a question on calc torque what does it mean on the chart and graph it obviously doesn't show exactly is that column just gains?

Hi Dylan! I’m having some drivability issues and wanted to see if I could send you a log to get your thoughts? Would you be willing to help me out?

Can you look at my log and see how the boost is? It's the 2.5 sonata N-line

Hi, any recommandation on how to get started with a WRX 6MT map 6 tune? I just got the JB4, and I'm currently running map 2, and would like to a little bit more from the 93/94. JB4 tech forum doesn't seem to explain it much.

[m.pietro]

You mentioned about Colorado and altitude, well my understanding this is valid for naturally aspirated engine only, boost engines will make the amount of boost regardless of altitude. Am I wrong?

[armandoreyes]

Yo I have some questions about some parameters in the JB4 app! I’m running it on a KIA Stinger though!

[KushestWRX]

Nice video, could you explain what the adjustments do. I'm mostly confused about adding and subtracting from the fuel bias. Does a lower number add fuel or reduce fuel?

Hey bro thanks for the video. If I set my max boost to 25 and failsafe also does that mean that my boost settings can not exceed over that number or do I look at my target to get max value?

[jeterbox]

So if I'm understanding correctly I could possibly up the boost slightly in map 6 save and then run map 2 and get more boost....this is very slowly starting to make sense to me

[trythis]

Hey Dylan how do we read timing on the logs? Thanks!

[jeterbox]

Sorry one more ?, since I've updated I automatically data log when going to full acceleration at anytime i dont push to data log, is this a new feature?

[jamesbaimbridge]

Also how do I get the reader to see the chart and not the graph is saying I need an app to read it?

[rubenayoso]

Can you look at my log? Where can I send you the log?
