You will need to go full throttle up to redline for a proper log. I have no doubt it will hit all the boost targets without fuel and timing trims in map1 and the conservative map6. Map 2 is the question...

I'm new to this JB4 application and want to play around with MAP 6. I like Map 2 in my X5 M50i but I feel its a big hit midrange than it falls off on the top end making the X5 feel like it ran out of juicy. How would I setup MAP 6 to give me a solid pull all the way through vs a big punch than nothing?

NO, not the same board. Ando at Support@jb4connectkit.com helped me out... informative and efficient. The correct board is on its way. Thank u

BMW finally got around to upgrading my software to 07/2021.20 from 03/2021.40. I noticed immediately how firm the car's stance feels while driving and how smooth the car drove and shifted gears. Testing is with no JB4 as I had to take that off for a visit. But the car feels so much easier to control, and the power on stock felt beefy compared to the previous software. Dare I say it felt like a different car??? Anyhow, this is just my first impression after driving it a few hundred miles on no tune and just a software upgrade.

Fast forward to today, 19 Jul 21. I drove the car a good bit before work on the way to grab some coffee as I wanted to test the car's balance with a new rear sway bar. I want to say this investment is well worth it. It took 1 hour to install, using a lift and making sure my 4-year-old didn't run into the street.

Altogether, it was four bolts and two nuts. The bar itself was tricky to remove once unbolted. The driver-side control arm needed raised an inch to slide the bar out.

I hope this is informative.

Couple of us 523hp m550i jb4 users are noticing that with launch control, 4th gear short shifts when you are running a quarter mile sprint. Problem doesn't occur in map 0. It loses quite a lot of time from the run and it pretty annoying! Is anyone else here aware of this as well?

I'd guess its shifting at a particular speed. And since Map 0 has less power, it needs more rpm to hit that speed.

I did a LC tonight, cool and a little bit damp. The car did it from middle of 3rd this time, chucked me straight into 4th. Got me thinking it might be due to the fact LC operates with traction semi on, if the car detects too much wheel spin in knocks you up a gear.

I have not talked to you guys in awhile. I have not used LC yet but I am interested in your feedback.

Also, on another note please remove the charcoal filters in your intake track. If you have them and I did but now after removal the cars throttle seems much more responsive. It's a 15 - 20 min job and so worth it.

Does anybody have the CAN-Flap working on the G-series? Its not working on my car, with the BC button or the JB4Connect app.

How do I contact Terry or where do I send logs to? I think I am getting some boost creep after installing 🐈 less dp.

I did install the BMS wheel spacers 13m on the back and 10m on the front and boy what a difference in the stance. I sprayed them with high-heat rust-oleum in attempt to prevent rusting. It's like my 335i when I added 9.5s to the rear.

I started poking around in the engine bay and the TMAPs are very easy to get to and have 3.5 sensors.

The jb4 should be here Monday so il install it and do my best to stay under 4k rpms. Easy to do on the small german roads but the autobahn is a different story.

Thanks

Hi Zack,

Please post a pic of your car with the BMS 10mm spacers front and 13mm rear. I want to get spacers but I don't know which sizes to get for a semi-flush look. I also ordered the MSS springs. Hoping to get the car in a nice stance.
