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! -Jose |

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.

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.

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
