It's all messed up, JB4 map 2 stock gapped, with intakes only.

Omg, reading through this thread has me feeling so glad I’m staying stock.

Scott ....Why do you add mods to your car without correcting the original problems? It is not rocket science to add a JB4 piggyback.....but then you add other items to your mess without solving the JB4 problems...You are clearly in over your head...... Wash

He’s got me scared to even put that damn thing in my car. I’m good at changing out pre-gapped spark plugs and plug and play wiring but damn this all sounds like a good way to destroy a perfectly good sports car the way it comes from factory.

There are risks with everything. But I can say (from all the threads listed on this forum) there are a lot more positives with the JB4 than negatives. Plus it hasn’t been determined yet that the JB4 is the cause.

 

[Scott Curry]

Yeah I doubt it's the jb4 it's just adding fuel and boost and some timing. and I think it works on just about every car out there it's just the few that have ignition spark problems some sort. Generally it's either user error or coil pack spark plugs fuel. It doesn't help that these cars are that temperamental though. I could beat on my Subaru all day long with 23 lb of boost, stock plugs gapped without even checking them, shity 91 octane and never have a misfire... So it's definitely the cars being temperamental.

If you don't want to scare yourself then don't spend time reading support threads.

We've tuned over 1300 Stingers now. They are pretty solid other than the rare plug or coil issue that takes a little leg work to sort out. Usually then those issues come up you can still run at factory power levels problem free until resolved.

 

[Terry@BMS]

So it's definitely not fuel, I just had major major misfires and it's weird it's at a partial throttle coming uphill with load. I can almost get it to just continue to misfire at a certain position on the throttle. It's absolutely horrible. When I put the stock mid pipes back on I'll have my guy pulled the plugs and check each one to see if there's anything that has happened to the plugs. This is so disappointing and frustrating

Just put in some new plugs, Denos are $60 and HKS what $110? Gap them down to 0.020 since you know you have a potential coil issue.

 

[Scott Curry]

So put a second set of new plugs in?

 

[Scott Curry]

I got the denso's from you guys about 2.5 weeks ago

 

[Terry@BMS]

You've made this thread so long it's not practical for me to review the history here.

If I recall you ran stock plug gap and had issues, right? Then did plugs? What are they gapped at? Do the issues appear on map0? Map1? If they appear on map0 do they appear with JB4 removed all together? If they appear with JB4 on map0 but do not appear with JB4 removed then it's more likely a coil than a plug I think causing electrical feedback.

 

[Scott Curry]

Yeah you're exactly right stock plugs originally not gapped, then I got the denso's and got them at 0.022". Is it possible a plug is gone bad? What about torque settings?

 

[Scott Curry]

The guy that did the job for me is an Audi tech.

I’m not talking crap about your product there, Terry. It obviously is good for the most part, but it is a big risk for people like myself who aren’t great at aftermarket stuff and get overwhelmed and end up possibly ruining their car. And btw, I’ll read and post wherever I like. If you don’t like it, you don’t need to respond either.

No more likely running on the factory plug gap damaged a coil pack.

I asked some specific questions above I've yet to hear answers from.

1) Does it happen on map0?
2) If so does it happen with JB4 removed?

You're welcome to hang out wherever and do whatever you'd like. If you really want to scare yourself go hang out in a Kia dealer repair bay. We have one across the street here and I see unmodified cars towed in daily. Some remain there for weeks.

If I didn’t have a 125k warranty on everything other than regular maintenance items, I’d probably dabble in the idea of trying the JB4. I’m sure it’s awesome but I’m probably no better at messing with performance stuff than OP. That’s all I am saying. Not worth risking losing my warranty over some more horsepower. When warranty is over if my car will last 125K I’ll try it then but I imagine I won’t have the car by then since I only drive about 10k a year at most.

 

[Terry@BMS]

If worried about warranty you'd do a tune, regap the factory plugs or do Densos, and maybe add an intake. The JB4 and intake can be installed/removed in under 20 min for service visits.

Now if you damage something yourself like OP did here by running the wrong plug gap then you should pay for those repairs yourself. I'm sure he will be buying himself a coil pack sooner or later once we figure out what cylinder it is. If this is the thread I'm thinking about he first brought his car in to the dealer with aftermarket parts on so they are not going to work on it like that anyway. NEVER bring a modified car to the dealership. It should always be 100% factory to ensure your parts are not causing the issue and make life easier for their diagnostics.

I agree with you 100%. I really liked the Orange Virus tune on my Tacoma because it was 100% undetectable by the dealer. It was all loaded via the OBD2 and didn’t require any hardware on the truck but it also was nothing like the JB4 in terms of amount of performance gains.

I am curious though. Statistically speaking, have any number of Stingers shown negative impact on Engine/transmission/chassis following extended period of time running JB4? Did they have premature wear due to forgetting to upgrade other components besides the ones you’ve already listed? Again I’m a noob so take it easy on me.

I have the same 125k extended bumper to bumper warranty. I am also new to mod life and just jumped in. I read, watched, and researched. Over time I determined what I was comfortable with and what I’m not. I also seeked out my service manager and asked about my intakes and exhaust to make sure no issues with warranty. All my JB4 stuff including the flex fuel sensor I feel I can disassemble within 30 min for service calls. I pretty much am fine with most stuff except for the WMI. I didn’t want to do any ECU tune and chose JB4 because it was superior over the other brands (for me) because of the gains but more importantly gains with safety measures to protect the car. I liked those features. I also liked the fact the JB4 has been around awhile and manufactured for performance cars like BMW, Audi, Maserati, and Porsche. Further, I liked the support I saw that other JB4 owners were getting. That gave me the confidence to purchase. I have done all my mods myself (except the cat back because I don’t have a lift). I was scared initially. But with each mod I felt more comfortable with my car and gained confidence for more mods. You have to decide for yourself, but I am more than happy with the choices I made. The only regret I have had is not having my entire car wrapped with protection film instead of part of my car. Other than that I would do it all over again.

Nice! It’s good to know someone in the same shoes is willing to do that.
