Poll: Who is having issues with Spark Plugs?

[Angel]

Densos?

yes Denso 1 step colder....there cooked for what it seems

 

[Angel]

What’s happening in your logs and on the App for the jb4?

Logs are all Fock up....car is misfiring bad. Watch the videos, look at the first video. The check engine light goes on as I am recording it live lol

Does the app freeze?

 

[Angel]

Does the app freeze?

yes lol how did you know?

 

[Angel]

@Terry@BMS Is there a way of telling if your coil pack are bad with the JB4? By reading the data like ign 1, ign 2 etc....

 

[Kato_the_kia_stinger]

yes lol how did you know?

I’ve been having similar issues.

I’ve been having similar issues.

What parameter you run on map 8 ?

 

[Kato_the_kia_stinger]

What parameter you run on map 8 ?

The issue arose with Map8, but once it happened the first time, it’s happened ever since, on all Maps, including the app glitching and freezing.

What boost additive, flow, psi you run ?

 

[Adamdan]

What parameter you run on map 8 ?

I wonder if your running to much water or spraying to much early and it’s making the car sputter.

I have no idea I just followed the rules that I downloaded from BMS. My meth parameters were Meth Flow 90, Boost additive 50, and meth psi 9.

Maybe Terry can chip in his thoughts. I honestly don’t know what caused it, but what I do know is whatever damage happened, I noticed it after my second wot meth run.

 

[Angel]

I changed the 2 plugs and been driving the car for the past 2 days without any issues.

I have not tried any meth runs. I don’t think my coil pack are bad and that was my concern.

I will graduallly try map 1, map 2 again if I get no misfires the I am good.

After that if there are no issues I will try meth runs again.

Not sure what I should set my parameters to be.

If the coil packs would have gotten damaged by the misfire you would have had the same problem as soon as you installed the two OEM spark plugs. Coils usually don't get damaged, but when they do you will notice it right away as soon as you replace the plugs with new ones.

Before you run map2, make sure the plugs are gaped correctly (not sure if you did that before installing the OEMs back on).

I would not run meth again with the two OEM spark plugs, as those are hotter than the other 4 you currently have installed. You can run into detonation which will put you on limp mode or you will damage the OEM plugs. Even running map2 with the two OEM plugs is a bit of a risk.

Another thing to consider is the possibility of a contaminated batch of gasoline, temperatures are now rising and humidity as well, there will be condensation building in the underground tanks of the gas stations as temperatures start fluctuating. Try filling up at a different gas station, remember we are dealing with increased amounts of boost and the small things start having more importance in the proper performance of the engine, things like quality of the gas and ethanol, type of meth liquid, spark plug gap, etc.

Stay as conservative as you can while you receive the new plugs to prevent further damage. If after installing the new plugs the issue comes back after running meth then we can start thinking there is a value that needs to be changed on the JB4 meth map.

I’ve had coil packs go out on my 240 before. Your right it was not a miss fire here and there for me it was one cylinder would go dead then maybe work again for a while with heat change.

Thank you for the detailed information!

I did gap the 2 oem plugs to .024.

I think the issues was the plugs since I have not had any issues since I swappped them out.

I will wait for the plugs and then try wmi again.

Thank you for your help! I will also not use the Sam club gas, I will try Mobil or shell gas even thou is more expensive.

Can I gap my OEM plugs to .024 before installing a JB4 but with intakes and secondaries?

 

[robz32]

Yes you can. There have been members that have done that and are running with no issues on map2.
Closing the gap will have little to no effect on the factory tune.

 

[cncBilly]

Thx.

Yes you can.... but I would reccomend you get denso 1 step or 2 step colder ... part number is ikh24 and ikh27

Well, he has posted abot an issue with violently jerking, sounds more like a transmission related issue and not ignition.
I personally drive a 3.3 and so far the 3.3 stock have not reported any problems with spark plugs.

Hi! Late to the game but FYI my 2019 GT2 is all stock except a new exhaust and I am having the same issue... it’s at Kia now for the second time.
