*I am creating this post for those who are not in the initial batches* For the backstory and for those still asking why I did this, please see: 3.3TT - Creating True Plug-N-Play JB4 Harness (w/Fuel Wires) If you have inquiries, and you're in the first three batches, please also post in the...

As the title says, I just discovered the JB4 app themes (Settings>App Settings>Gauge Settings>Gauge Theme). The "Needle Fill" theme looks awesome IMO. Even has persistence on the boost meter so you can see what your max boost was over the past few seconds. Screenshots below. I looked into it...

As the title says, I'm wondering what exactly the fuel wires are doing. My understanding is that they measure the AFR (air fuel ratio) from the O2 sensors, then, somehow, trick the ECU into running leaner. With access to only the MAP and TMAP sensors, is the JB4 just telling the ECU, through...

Hi guys, I'm looking through my logs and noticed that my avg ign is all over the place. Sometimes it's 2, other times it's 22, and it'll swing anywhere in that range on any given day. Even within the same day, it'll range from 4 to 18 on the same tank of fuel, same map (Map 2, 93 octane most...

I'm looking to get the JB4 soon, but I'm not sure if I should re-gap my stock plugs, or get the Densos. I live in New Hampshire so our winters range from -10F to 20F on average. After reading a number of posts, it looks like I could have idle issues in the winter if I go with the, one step...

Anyone else having issues with this? Example, I'll get the app connected when I leave work, and just about the time I get close to my on ramp I realize it's closed itself. Not the end of the world, but it's annoying to miss out on a good log. That, and having to bump Bluetooth before it'll...

Community, I currently sit stock but will be purchasing a JB4 + Plugs + Intake/VT Big Mouth as my first performance modification. I do not want to risk any overheating issues or mechanical breakdown due to any lack of preparation. Will I be okay running JB4 MAP 2 or 3 with a stock FMIC &...
