Engine Replacement

Only map 1 or 2 can be considered mild because they only require pump gas. Map 4 on the JB4 site literally says: Map 4: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%. Yes thats more than a mild type of tune especially if you are not monitoring the amount of E85 in the tank, just estimating it during fill ups is not exact enough. Having the wrong fuel on an aggressive map can certainly cause engine damage and fast

You dont need a CEL to come on to do damage to your engine. JB4 logging exists to catch issues before they happen

Im not saying not to mod your DD. Im saying there is a difference between knowing what you are doing, and closing your eyes and hoping for the best. At least if youre going to close your eyes, walk slowly instead of running. You can do a map 1 or 2 tune on the JB4 and be almost guaranteed never to run into an issue as long as you regap and replace plugs (along with logging). Learning how to take logs is part of tuning, you cant be too busy to do it. All you have to do is post them here, tons of people do that and other people will read them for you

Look I dont want to shit on you when you already feel shitty. Ive made some stupid decisions too in my life, just havent posted them in a public forum. It take guts what youve done, I commend you for committing to learning from this.

I will not judge anymore. I and other people in this forum can point you toward links, posts, etc that might help you out for this car when you get it back or future cars. Just ask away
Fair enough.

Maybe I can look through the logs that I have recorded and collected and see if anything pops out.

I certainly didn't realize that the E85 mix needed to be monitored that closely.

It's not such a brave thing to post it. I'd rather lose and learn that just lose. Besides, I have read people doing what I did on untested mixes and even 93 octane. It's important to put it out there. I'd rather serve as a bad example than be useless. If by chance, this was a manufacture's defect that was brought to light. Then I am glad that it was early in the car's life. Either way, it makes me wonder how many people never share this kind of thing out of pride.
 
What a ride. Hope your daughter fully recovers. As for kia replacing your engine, well you got pretty lucky that they didn't immediately pull the mods caused this so you gotta pay up card. Guess that's one good thing about having a warranty. But yeah, you kind of did mess up with a few things: jb4 is a lier chip, so it will lie about some things to the ecu. The ecu is what controls the car, so you have to monitor and be fine with what the jb4 is lying about. That's why you have to use logs if you use an aggressive map. Map 4 is an aggressive map, as pointed out by others. as for e85, yes this car is very picky about e85. You cant run full e85, not even if you upgrade both fuel pumps. My car was tuned for 93 octane so I run an e30 mix, but I have a sensor so I know exactly what mix I am running. Lol if I roll up to my dealership with a blown motor then they will just laugh and tell me to get out. With a salvage title, I am the warrenty.

Wanted to post this for a while so here goes; First, "Didaho', this is not pointing fingers at you but instead, a word of "caution" to the Stinger owners who are "on lease", mostly "DD", and others who are "tuning virgins". (part of this is pointing to my self as well)

Before buying/adding any mechanical/electrical devices that would be considered "tuning mods", do yourself a favor and jump into some tuning "101". Whether online reading, online classes (a few I have taken) or hell, even "youtube".....The knowledge gained will give you MAJOR insight as to the direction you want to go with your vehicle. It's your "dime" and unless you are Jeff Bezos, you probably work hard for that dime and spending it on your Stinger is money well spent B-U-T tuning does take some knowledge/experience that doesn't come overnight.

I know there are others, but since i am a JB4 owner, I tip my hat to Terry@BMS for the knowledge and experience that he has contributed to the device/tuning community. Read a quote: "tuning is not rocket science but a science you can learn". Terry is a rocket scientist in the tuning world (not calling him a "nerd w/pocket protector" LOL) but you guys get my point and I am sure he has had his bad days as well.

To "get off my soapbox", tuning can be very rewarding but if not taken seriously, can be very detrimental. Do the homework and keep your pocketbook in mind before you take the leap. If the pocketbook can't take the heat when things go south, it is probably best to leave well enough alone until it can and THEN place your order for the JB4.....

Sorry LAP3, had to say it......

peace folks.

I tested out map 3 for a bit on boostane, but tbh, once you start getting into fuel mixtures it is a whole new ball game and I would not do it to a daily driver which is why I keep it on map 2. To each their own though, but I knew my limits, and playing with fuel mixtures was just one of those variables I was not willing to stress with. Shit, every time I go to the gas station in NJ ,where you can't fill your own tank, I have to constantly look over my shoulder to make sure the guy selected 93 octane. Even on map 2 I am still pissed I have to replace the spark plugs every year so I can't imagine constantly monitoring logs and fuel mixtures.

Oregon too! The one time my windshield wiper was yanked up to clean the glass, and hit the rear edge of my hood, was coming home through Oregon; the attendant did that; I didn't stop him soon enough; but at least I had had PPF installed the week before, so, it's only the plastic that got scored. Do they clean windshields "for you" in NJ, or just pump gas?

They might do it if you ask. All the Hess stations are gone, they were the last of the full service gas stations - window cleaning, oil check, etc.

Things have changed though. When I pumped gas as a kid, people paid with cash and tipped, so I did all those courtesies.
 
Have a question I have a 2020 stinger gt2 awd I seen the blown motors what years did you have and any transmission problems seem like mine is not shifting right in any mode like it gets stuck and does not down shift

They do, but not very often. I don't seem to care as much about them doing it, just as long as they are not manhandling it. I did see scrapped paint on the top of my hood and can't remember where it came from. Likely user error on my part.

I would go to the dealership pronto - hopefully just a TCU issue and not a mechanical one.

piggybacking off this... at what mileage do the engines and transmissions grenade?

My car is stock and a 2020 so it has a solid 10 years to cover both the engine and transmission under warranty... just curious when to expect to see the problems... I think the car has around 6500 miles now at this point...

what?? at no mileage. Its certainly not an issue on the Genesis side, and Ive seen no threads here either with stock engines and transmissions having major issues. Do you all know something we dont? Maybe a rash of problems in social media groups??

Depends on the color...

Oh, sorry. I see you have a white one. They reserve the best engines for red cars with red interior.

I could be wrong, and I have no problem admitting to being wrong if I am indeed wrong, but I could have sworn I have seen people saying that their engines and/or transmissions have failed. Granted, I believe all of the reports I have seen were discussing a none-stock Stinger... but with that said... a stage 1 JB4 tune I don't believe is much of a hardcore mod... Again, granted though, I could be wrong.

Haha for sure!! :p

OP in this thread was running map 4 while not monitoring E85 levels. Ive not seen any threads with a mild map 1 or 2 tune run with the proper plugs and fuel having any issues. You are mistaken, which is a good thing in this case.

Glad I was wrong then! :D

From what I read, and this is rather very reassuring, Kia under-tunes the engine and transmission... the powertrain can handle much more even stock but they like to play it safe and keep it reliable... hence the solid 10yr/100k powertrain warranty... :D

By the numbers the A8R50/A8TR1 transmission isn't rated for much more (383 ft/lb) than the 3.3TT outputs stock (375 ft/lb).

List of Hyundai transmissions

Not a lot of margin for error IMO. The engine might be fully capable of outputting more power, but I doubt the transmission would handle anything we could throw at it (over a long period of time/life of the vehicle/warranty).

I'm committed to learning, and part of that is admitting mistakes. A little big for my britches seems to be the proper saying.

The fastest car I had ever had before was a Civic Si. I went to get a Telluride but test drove this and never looked back. Pushing the envelope become an obsession.

Pushing the envelope is fine but having kia pay for a motor out of their pockets because you threw ethanol at it will eventually come down to us as consumers.

Soooo, ethanol is the reason it grenaded? Exactly how did that happen?

Nobody knows since there's no logs... but running a 7 psi with a guess on ethanol content Is a VERY likely culprit
