JB+ or JB4

Post by Danny1989 »

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.

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.

Can you switch between maps and back to standard without messing about under the bonnet.

Might also be worth considering the bluespark as its a similar price to the jb+

I'm currently considering the jb+ or bluespark for my m140i.
