Is JB+ safer on engine than JB3 or Procede?
So from what I have been reading everyone says that the JB+/SSTT is safest way to go if your only doing ECU mod.
But, without fuel control, how can this be? Do our cars run rich normally? All the JB+ does is up your boost without changing fuel control right? So running lean is not a problem with only 2-3 psi increase in boost? P.S. this is for daily driver in Socal with fairly warm temps half of the year. |

If you keep boost in the low range (JB+ at standard setting) it should be easier on many components.

I think the closest to a consensus you'd get is that significantly less boost is generally safer than more boost, given reasonably good tunes or hardware.
These devices are likely safer, IMO, only to the extent you run MUCH less boost than most people run on the full tunes. However, again IMO, the higher end tunes or flashes would be safer at the same or comparable boost and hp gains (as they control more engine variables and can include more safety measures). Realistically, if you are conservative on hp increase (e.g., adding 50-60 whp with a full tune or less with a boost controller) and not pushing the limits at a track (i.e., a daily driver), most of the tune options for n54 seem fairly safe. Your mileage may vary and your engine will blow up immediately after installing a tune if you base the decision on this comment ;-) Good luck. |

Shoulda bought a M3
I want a remote controlled JB+. Why doesn't this exist yet? Run stock setting all day and then when some Infiniti G37 is tooling around with me, I can just turn up the boost +3 PSI, FTW! Maybe I can ask him to pull over while I adjust my boost settings. And I don't want to enter my ECU so Procede is not really what I am looking for. I know people say it's easy to take out, but not if your car goes limp in the middle of nowhere and you don't have a spare car to use while you get it towed home to take off the piggyback and then get it towed to dealer that won't give me a loaner. Worst case scenario of course, but hey, it could happen. |

if your car goes limp you can still drive it. it really isn't that difficult to get at the ECU, if worse comes to worse take it to a shop or knowledgeable person. they can do it for you in 20~30mins max. i know you can dial the boost on the procede to whatever you want, not sure on the jb3. |

On Jb3 you just change map to a more performing one on the fly.

Saying that the closed loop fuel system is "good enough" to support higher boost either suggests optimism or a lack of understanding. Shiv |

i am pre 29.2 and was advised that the FP wire was not needed for JB3 1.1. but now Rev4 increases fuel pressure below 2500rpm.
So now I am required the intercept this wire. is this for invisibility or is there risk of running to lean? |

Im not a car expert but i say SSTT and JB+ HURTS your car MORE than jb3 or v3. Just IMO. I say this is because of the feeling when it drives. JB3 and Procede tunes are so much smoother and has WAY less jerky motions. I had experienece with JB3 JB2 JB+ SSTT and V2 procede. SSTT and JB+ seems to be confused at times or the car seems a bit confused at times with just the upping the boost method. Car seems like its kicking in more boost but feels more grinding and heavy load on the car. Bottom line going from JB3 to JB+ the car felt like SHIT. Also my car was throwing limps crazy on JB+ but rarley on JB3. Overall i think the "real" tunes are way to go in safetyness. Power and feeling and smoothness is different night to day. JB3 and Procede> sstt/jb+ imho.
Not to mention i threw a shitload of vanos codes with the JB+ and never with the jb3.. Idk why tho.
