Recommended JB4 map

Just finished installing my new JB4 on my 228i 6MT. Which map do you guys recommend I use daily? I only have the JB4 and a muffler delete, so stock down pipe and charge pipe. I've searched a bit and saw people recommend not to run map 2 with the stock down pipe, but that was posted about 2 years ago. I'm wondering if that's still a good idea or if I should stick with map 1 for daily use.

Otherwise I'm loving the JB4 so far. Super easy to install and set up with the OBDII steering wheel controls. The car feels a good bit faster on both maps 1 and 2.

I daily the car on Map 5 which is like an "autotuning map" and adapts to octane and conditions... If I take the car to the mountains or just want to feel the cars "full potential" I switch to map 2
Never have had an issue or CEL!

Thanks Jose, I think map 5 is different on my n20 Jb4 compared to your n55 though. BMS says map 5 is a recommended map for the x20i engines on mine, where the n55's map 5 is an auto tuning map. Not sure how map 5 would work on my 228i.

True the maps are different in each models, I would just say to daily drive it in map1 which I believe is the safest one (That's what I think, don't quote me on that lol) and you'll be set!

That's definitely my plan for now. Was just wondering how "unsafe" it is to run map 2. I'll probably do what you do and go to map 2 when I'm doing some driving in the mountains or other fun roads. Thanks!

I've had my jb4 for about a year and have kept it on map 2 for most of it, and never an had an issue. I do work from home, though...so probably drive less. I was actually going ask what would be the best, conservative map for daily driving after I install the exhaust, catless dp, and chargepipe? Don't want to push it too hard.

From what I've learned if you have an aftermarket downpipe and chargepipe you're definitely fine on map 2. The DP/CP are the biggest issues with running higher boost from a tune because they are plastic and aftermarket ones are metal.

Run map 1

I would only run map 2 after datalogging and making sure car is handling the extra boost well

If you are going to use map 2, i strongly recommend you send a datalog to BMS first
