Found a bug in the firmware causing a false alarm IAT/boost sensor fault. Will add new firmware to the first post shortly that corrects it for anyone getting it.

Air temp, 58f. Half tank of 93... Best 0-60 was a 4.8. I was traction limited on most of these logs when either getting to the top of first, or shifting to second. Also had slip issues in first when the boost really came on... for science...

Set 1st gear to 3psi to reduce boost down low by 3psi and see if that helps the launch!

Hi Iím wanting to get the JB4 for my car and I was wondering if the software is finilized or are you still beta testing it. Also is the only parameter being affected by the jb4 the boost pressure? How about fuel and timing? If I remove it will the dealer see any trace when I take it in for service since it connects to the obd2

Boost, timing, and fueling are manipulated, and you can confirm everything is healthy by running your own data logs.

The hardware itself is finalized but we will be doing regular software updates to add more power and features as continued development dictates.

Ok sounds good, did you run any dyno pulls yet to see the difference in hp and trq. And how about when I bring the car in for service?

I've been inspired to try a 0-60 run in my Q4 on Map 2.... I did cheat a bit because it's cold out

4.625 sec according to the app

Hey just finished installing my jb4 a couple hours ago. I was kinda upset at first because i thought i ordered the wireless mobile kit but instead just the basic wire but itís all good now, just ordered the mobile kit and the ride just in map 1 is a lot of fun. One issue (or maybe good thing) i ran into and the main purpose of this post is that upon first start up i got a light telling me that start stop is unavailable and it has not gone away since. Any idea what might be causing this? I personally never use this function anyway but the light on the dash is a bit annoying. Thanks!

Got any logs so we can take a look at firmware or anything unusual?
