JB+ or JB4

Post by Danny1989 » Mon Feb 19, 2018 3:53 pm

Hi

I'm new here, recently bought an M135i lci and now want Jb+ or jb4. Rest of the car is stock and i don't plan on anything other then maybe a cat back later in the year.
I'm not too fussed with all the extra stuff you can do with Jb4, i just want a little more power.
Does Jb+ run the same in terms of power and the way it's delivered as say the Jb4 in map 1?

Hi and welcome!

The JB+ gives a very noticeable gain and can be fitted/removed in under 30 seconds.

Highly recommended if you don't plan on any further mods.
Now - E92 M3, DCT, Comp Pack, Alpine White.

Gone - 2016 M135i

Why not go for MHD flash tune? Just a obdII cable then you can flash new software with your android phone.

If choosing between jb+ and jb4 I’d take jb4.
I first had jb+ and did not like power delivery, jb4 is different. Mhd might be good, unfortunately only works with Android.

Thanks.
Have you got a JB+ fitted mate?
I'm still a little unsure as iv read the Jb4 gives you not only more power but it's smoother, is it worth the extra £300 though.

Yes I did. Jb4 gives clearly more power even with map1 and more important is that power delivery is smooth and also top end with ewg version feels powerful. Jb+ was not good at top end and power delivery was bit jerky, low/midrange power increase was there but as said didn’t like the power delivery.

Ok, that's the sort of info i was after. Will get Jb4 ordered from ML performance.
