JB+ Install on X2
Thought I'd share some pics on installing a JB+ on X2. It's pretty responsive now. I believe the stock engine is OK, but let down by the gearing and programming of the Aisin transmission. It seemed to miss a step now and then.
Only do this when the engine is cold and have the key fob out of the area.

I haven't done much research on it for these motors specifically.. but on the N55 motor the JB4 was 3 plugs (the others were optional for flex fuel and electronic wastegate). Not a ton harder than just one plug. The JB+ has always been just a boost controller turning it up a little bit.

I wanted cheap, simple, and a little more hp for a little more responsiveness. A quick jab on the throttle and a you get a little lurch forward. No pin you to your seat, power sliding, tire smoking action.

Good job on the write up. For anyone debating, it's a must-have mod for the X2. If you can't justify the price, wait to buy a used one.
Run the JB4 on map 2 and you're going to get a much, much more responsive car. You'll notice the power increase as well. |

Sorry, I don't mean to hijack the thread.
But AllEyesOnMe , which JB4 are you using? Do you have any idea if N20/N55 JB4 will work with X2 B48 engine? Its because there are couple of folks selling used JB4 on the bay that I'm interested with. |
