Oh boy, sorry to introduce yet another option to you..lol. It's a kit from BMS, short for charge pipe injection. Basically, it's a 7th injector that will allow you to run more E85, thus making more power. Here's the thread: https://www.n54tech.com/forums/showthread.php?t=64602

There are some very helpful and knowledgeable members and wmi experts on the Facebook page and n54 forum. You'll have plenty of support if you go that route. 👍 I'm in the same boat, I want to go faster but not sure if I want to go with WMI, CPI, or a tune. Decisions, decisions....

Terry from BMS said on the FB performance page that techs will still be able to see you're tuned, even if you switch out ECUs. There are values stored elsewhere that are supposedly easy for them to find if they really want to. As for numbers, they're right in line with the JB4, in fact the...

I have the Windbooster and can't say enough good about it. There are many modes to choose from, and each mode has up to 10 different levels of sensitivity. There's even a mode to disable the throttle altogether, in case someone tries to drive it without your permission. They do come from China...

If it fell all the way to the bottom you should be fine. I dropped my phone down there and I had to take it in to Kia to have it retrieved. I was embarrassed but I had several people there tell me it's happened "plenty of times." Mainly I was just glad I didn't damage the engine in any way...

You're welcome. It's a fun process but just know modding can be addictive. 😂

Well, if you want to keep it simple, most would recommend the following package, which contains everything you need to make roughly 450 whp: https://burgertuning.com/collections/kia-hyundai/products/450-horsepower-kia-stinger-hyundai-genesis-package If you want more, to that package you could...

Have you tried the installation guide page? http://www.n54tech.com/instructions/kia_stinger_install.pdf

You AWD guys have it good; I'm currently stuck at 4 secs flat to 60 because of wheelspin. I run the same trap as guys using WMI, so I know the power is there, if I could put it down.

And that last bit is why I started braking instead of just letting off the gas. I had a kid in a 392 charger claim he reeled me in and passed me, when in reality I let out because I was two cars ahead. 😂

That's an excellent time, especially on such a mild map. Just think what it'll do with some E and moving up to 3 or 4.

I'm thankful I bought out my lease now; I would be about 20k over when the 3 year mark rolls around in Dec. I took a voluntary layoff when this outbreak hit and I've done a lot of road tripping. I'm probably going to stay furloughed until January, so, the miles are gonna keep on rolling....

I don't know personally, since we have 93 here, but, I just watched clips of a Stinger also in CA, running a jb4 on map 2 and 91 octane. His car seems pretty quick so it appears 91 works just fine with map 2. 👍

I have nothing but respect for those little hatches now that I know their full potential. Friend of mine has one and his is truly FBO (lots of those guys call them FBO but until they're running the fuel system too, they're not, and leaving a lot of HP on the table). We have done an insane number...

You're on version 16; the middle name is the firmware you're running. There have been some decent updates since that one, so you should move up to either v19 or 20.

I've had that happen a few times and usually it's traction related, like hitting a bump in the road or there's a slight dip. With the pedal floored, the ECU cuts power and it causes a major bog. Me personally, I wouldn't worry about it, if it didn't throw a code. But, if you're concerned, you...

Sorry to see you're having troubles with it. Are you registered on the jb4 board? You can try asking for help there; Terry is sometimes online til late and will answer questions. https://www.n54tech.com/forums/forumdisplay.php?f=39

I was under the impression the fuel wires are already included on the newer JB4 model's enclosure? Or do you already have one?

I have the fuel wires, yes. I don't even bother disconnecting the jb4 anymore though. I went in for an oil change once and forgot to take it off first. I figure well they know now, no sense in going through the hassle everytime.

It's an optional add-on, you don't have to have them. While not 100% accurate, there's an e85 gauge you can display on the jb4 app that will give you an idea how much you're running. I use that and simple math when I refuel; I usually don't get gas until at empty, so I pump 93 first and then...
