N20/N26 JB Plus or Dinan Sport to JB4
Has anyone gone from a JB Plus or Dinan Sport to a JB4 on their N20/N26?
Would be very interested in hearing how much of a difference you saw between the two. |

For the X1 the JB4 has full E series wheel controls and in dash map switching, really cool interface. And great performance gains.

JB plus. It gives you the exact same power as Dinan but 100 bucks cheaper. I've been running mine for close to 3 years on my 335. Once I flash mhd I'll be putting the plus on my wife's 320 I'll chime back in once that happens

I've currently got the Dinan Sport (which I have no doubt is very similar in performance to the JB plus), thus why I'm really interested in what I would gain by going to the JB4.
Thanks Mike, that is some good information to know. |

I currently have Dinan sport as well and am going bootmod3 in the near future. I should have the car flashed in the next couple of weeks. I would recommend you do the same. If you're willing to wait, I'll do a full write up on the switch once I get bootmod3 installed, and after that you can decide if you want to make the same switch I am going to

I know this one has been argued many times, but given that I still have CPO warranty coverage I'd be leaning towards the JB4 since you at least have a chance of removing it and avoiding detection.
Mike, I know there is logging and I would expect more flexibility in what you can do. But what can you tell me about the performance gains of the JB4 versus the plus & Dinan sport? |

So it looks like I've found my answer in that it is basically boost control only versus a much higher level of control.
All which ultimately provides a safer tune while giving smoother and a bit more power. |

I know you asked for mike but, while I'm here lol... yah, JB+ and Dinan sport only control boost via TMAP sensor. JB4 controls boost as well, but also other parameters as it connects to more sensors and thus has more control. however, don't expect smooth power from JB4. I don't think it will be much smoother than Dinan/JB+ if at all. I can't speak from experience, but generally, really smooth power can only be had with a flash tune. Piggybacks just don't have enough command over the ECU to deliver smooth, clean power.

You choose what's best for you of course, but the flash will always get my votes due to safety, power, and ease.
