Burger Tuning JB4 for Kia Stinger!

Dumb question of the day: Do you need the OBD2 add-on cable to get these logs for Terry ?

@JohnG7 I will just leave that there for you bud

it should be plug at all time if you want to get the gauges to work and log

Yes most of the good stuff comes from the OBDII cable/CANbus.

Yes most of the good stuff comes from the OBDII cable/CANbus.

Second dumb question of the day: Is that the "BMS Data Cable" option when purchasing a JB4, or do all JB4 have the OBDII connector by default?

I just bought a JB4 from another Stinger owner and I would order the required cable right away so I can install everything all at once.

Thanks a lot for your time !

Edit: Nevermind. Just contacted the guy and he had the OBD2 cable too, so I'm good with that. Thanks and sorry for taking some of your time

Don't worry about me bud, .022/.024 was just a suggestion. I GAPPED AT .024 and would GAP .024 again. (nah, now .022 on next set).

There was absolutely nothing wrong gapping at .024 MR EXPERT !

Edit to add--> My factory OEM plug gaps ran from .032-.036. That's a problem...

How many have had problems gapping Densos to .024?

None ! But I did hear many HGK blowouts.

Another edit: While I am gapped at .024 now and have had no reason to regap, I will stay gapped at my .024. My spare set will be set to .022- which seems to be proven now.
I have learned .022 may too be ok, but if .024 works, it works.

Agreed. I think you are good. I don’t think .002 makes a difference. I think stock plugs are gapped way higher anyway. Correct me if I’m wrong someone. From the various post I have read, people are gapping from .020-.028 .024 seems pretty reasonable.

I gapped at .024 and am second guessing myself. Was on my to do to regap to .022. Perhaps I'll relax about it.

Having the gap smaller may be more important for running a higher map with more boost but likely the lower maps like 1/2 could get away with a wider gap.

Please understand this is nothing personal and just trying to help.

Yes you may be okay, but why choose to increase your chances of misfires and have lower performance?

There are multiple reasons Terry/BMS states to gap the Denso’s at 0.022 and not higher. He’s testing different gaps and found optimum performance is at 0.022. Also the lower the gap the easier for the coils to produce an effective spark while under higher amounts of boost. So more potential performance and less wear & tear on the ignition system are just two advantages from using the proper recommended gaps.

And I do agree the stock 0.034-36 stock gaps were a big problem, but I do know of multiple people that had misfires even at 0.022-0.025 and dropped to 0.020 for smoother performance especially at higher boost levels.

So unless you have a legitimate reason and/or more experience than the creator of the JB4 I’d think it’s only logical to follow his recommendations instead of experimenting and increasing your chance of issues & less performance.

Terry is who I talked with when I was getting ready, he told me way back that .022-.024 was what I needed to gap my Densos to, so I gapped to .024 (almost 2 years back).
When someone makes a statement that someone shouldn't do the exact thing that Terry said, and it has worked GREAT for many YES I WILL SAY THAT PERSON IS INCORRECT.
Another edit- I must admit everything I see from Terry now does recommend .022 gap and looking back it's all I see from Burger now and for the last year. Early on most just recapped OEM to .025 and all was good (on good fuel and maps 1-2). I just installed Densos gapped at .024 and all was good.

So, that was a very legitimate reason and I would do the same today or tomorrow.

Just how many people have had a single problem using Densos gapped to .024? About the same that have problems gapped to .020?
So, I'll stick to my .024 and will gladly push my tunes using good 93 fuel.
So again, how many? (again gapped at .024)?

And I have seen and read just about everything you guys have, Terry stated .022-.024 to many, not just me. You are welcome to gap whatever you want- I'm not changing mine.
And it seems like 2 years back, was when my decision was between Racechip or Burger.

RE-EDIT- While many of us followed the instructions given seems like Burger has changed much documentation to now read .022 and not .022-.024 as before. It's not hard to find previous documents showing recommendations of .022-.028 in many threads.
Since Terry himself is who told me .022-.024 was great, I still believe it is fine- maybe their further testing has shown .022 to be preferable (I'll be dammed if I'd regap from .024 to .022).
I still can learn, but I too know what works when it works.
Now hopefully the thread can return to it's old self. AND realize, I never recommended anyone to regap to .024, I stated .024 works fine and works for many- BUT my spare set will be gapped to .022.

So ultimately I made the call to go 0.024 because I knew that I’d be maxing out in map 2, wouldn’t be going WMI and was happy to redo it if there were any issues. So far the car feels strong and I’m not getting any misfire codes.

Ultimately I will let Terry@BMS tell me if there are any issues looking at the logs. If there are, I’ll regap, if not, I’m happy having a slightly larger gap for more complete fuel burn.

Got on a dyno to see what numbers I get.
I had "only" 439ps last spring with JB4 and WMI on my otherwise stock car but my settings were far from optimal.

Same dyno, 6 months later
-> Best run : 494ps 70kg.m (= 487hp 504lb.ft)


Map8, 83% ethanol, BM7 nozzle (700cc).

They turned off my car and the bluetooth connection expired so I don't have logs of the 4 pulls (feeling so stupid..).

I still have the stock exhaust on, so I hope to break 500 next spring after I make improvements.

FYI, AFR does not exceed 11.7 and no TDC fooling.

There was a lot of angry typing yesterday.

Very nice and impressive results, especially with stock catback exhaust.Looks like the primary DPs definitely add about 20-30whp and you’re basically matching the stock turbo record right now. With a high flow catback and the right DA you may just break the record and hit the 500whp mark!

Curious what your “boost additive” & “signal scaling” settings were for that run?

Peak numbers look good! bummer on the logs, if for nothing else to see if it has any more power in it.

I am really curious about the drop at 6.2K RPM.
But without a log, it will forever remain a mistery...
