I had a software programmer that has the tools on his laptop and the OBDII connector and he was able to program a host of cool features to my 2018 BMW X1. Ours are made differently than those sold in the USA for example the windscreen and glass is thicker for better sound insulation and the vehicle comes with the windows already pre-tinted and a few other differences. My programmer was also able to use a software to bump up the HP and TQ on sports mode (turbo and other parameters) plus I added a BMW Cold air intake kit. The jump in HP is very noticeable and of course this affects the gas mileage. Also when I start the vehicle it no longer starts with the auto/start stop. When I put it in ECO mode (highway) it turns that feature on which it also does when the vehicle is low on gas too. I hear a lot of good things regarding the JB+ chip however some BMW dealerships will also program the ECU for a small fee ($400 - $600 unofficially) instead of buying a Dinan license. But you have to be discreet about this and not everyone does it. You need to know someone who knows...if you know what I mean.
