Burger Tuning JB4 for Kia Stinger!

[Angel]

I have an Intake and JB4 on Map 1 using 93 Octane on my 2.0t, yet my 0-60 times are in the 6-second ranges. Am I doing something wrong?

Yes you should of not got the 4 banger you need the 3.3T LOL

Hi Terry

I just did two pulls on my way home, with map 8.
They are 2nd gear pulls @ ~37mph.

Could you please have a look at the logs?
Do you have any idea why the throttle closed two times in the 1st run. Is there any factor is causing this?
I also wonder why the ECU PSI is so low at the beginning (below 8psi), is it normal?
I've seen the car use more boost in other days, with the exact same settings.

Thanks as always

The Throttle closure when you switched gears

155mph? what is the temp there iats were very low. What are you using for fuel?

Logs look good. I don't see any throttle closure. psi2 is manifold boost. When it starts to drop relative to pre-throttle boost more than maybe 2psi then you have early throttle closure. At moderate throttle closure you'll see about a 5psi variance.

Boost is lower in 1st gear while the turbos spool up.

HEs also on meth. That helps a ton. When you getting your BMS meth kit!

Thanks!

Sometimes in the same conditions (same road, same gear) there are no drops in throttle (stays at 100 the whole time), sometimes one drop, sometimes two.. Is it random or is there something I can do to prevent it? And does it make the car slower?

 

[Terry@BMS]

That's irrelevant. Throttle is used to regulate boost to target among other things. Looking at the ratio of manifold boost to pre-throtlte boost tells you if it's something that is slowing you down or not.

Terry dropping us some knowledge today.

Spent about an hour on the phone with force fed performance today. Excited for what your guys are working on Terry! With you and Justin working together this platform is going to be crazy in a year.

Thank you. Learning every day!

Terry/other knowledgeable folks, would you be so kind as to take a quick look at the attached log and let me know if all appears as it should be? Injen intakes and Denso plugs, otherwise stock.

Installed JB4 last week, sure feels mighty. On Map 2 with what seems to be an effective octane booster to get to 93+. This is just a little opportunistic roll on, nothing special...no drag strips for me.

Also...for others who are looking for more info about the JB4 logging parameters, I found this most helpful: Logging Parameters and their Meaning - N54Tech.com - International Turbo Racing Discussion

Log looks clean but log v8 firmware next so we see timing in cyl 2-6. That is normally a better indicator of how octane is looking for the boost levels.

Aha, will do. Thanks!

Hmm. I attempted to ask this in a thread that got thwacked summarily. So visibility to timing on all cylinders will help indicate octane...does it provide sufficient specificity to support a soft octane gauge option in the mobile app?

Yes among the things we plan to develop for the Stinger is an autotuning maps like we have for several of the BMW applications. This concept uses learned octane & learned ethanol values to optimize tuning for the maximum safe performance for any given octane, climate, situation, dynamically.

Excellent, thanks

Up to what map could I run using 93? Map3?

Could you take a look at my log? I deleted the cells that didn't apply to what I needed looked at, theres 2 runs in there.

Mods are: BMS WMI, Mids, muffler delete, CAI, denso, 93 oct

Even though I'm no expert, it looks like a very neat log to me.
