I just picked up my '22 B46 330i. Want to put a conservative tune on it, nothing too crazy, just a nice pickup. I will never run E85, but I do always use 93.

Thoughts on these different tuners? Is there another brand I should consider? I'm leasing, so not interested in a flash tune.

The thing that gets me about the JB4 is that it's only one plug, whereas the Dinantronics Sport is 2, so that seems to me like it has a better level of control of what it's doing than the JB+, but the JB+ lists a higher horsepower gain.

The JB4 obviously is it's own thing, but I'm wondering if it's worth the step up from a JB+ or Dinantronics if I don't plan on doing other mods or running E85.

Thanks for the help!

I have the Dinantronics… it's a glorified boost controller. Super easy to install (and uninstall) with an easy to use app. My butt dyno fully noticed the extra boost across all modes and has made jaunts on the Autobahn and my first trip to the ring with the 330i pretty fun.

Is it ground breaking? Nope. Will it get you sweet Draggy numbers? Nope.

Is it great for the money and super easy to use? You bet.

Maybe I go the DME tune route at some point (I have a 2019) but that's a huge pain. In the meantime the Dinantronic is a great option for me.

Thank you for the info!

What mode do you run it in? I noticed it has several, but their websites doesn't mention the difference between them or what boost amount over stock each mode targets.

Around town in speed averse Netherlands I typically use Sport or Sport+.

When I head east to the land of fun driving I'll bump up to Race.

I honestly couldn't tell you what the PSI numbers are. I suppose I could log them with BimmerLink?

No need, thank you.

Maybe Dinan_Engineering can chime in with more info on what the Sport targets on each setting?

Varies a bit per application but generally speaking across all of the SPORT's its ~+2 PSI for Sport, +2.5-3 PSI for Sport+ and +3.5-4 PSI for Race.

Thank you! Super helpful in making a decision.

Jb+ and Dinan sport are very similar, you do get Bluetooth connectivity with the Dinan sport to change boost.
With the Jb+ you need to open the box and manual change boost.

the JB4 is its own thing, it'll provide better power, safety, and smoother power delivery than the boost controllers. Even on a stock car.

So you're saying +3psi on a Dinan Sport and +3psi on a JB4 aren't the same thing, right?

In terms of power, they are. But since the Jb4 can monitor your car and ensure it is handling the added boost well, it can add even more than 3 PSI.

Now, if you do not want the extra power, do not care about the smoother delivery, added features, and the safety failsafes, the boost controllers, are the better option since they'll save you some money.

I think what I want is the safest and smoothest, not the fastest, I'm fine with 3psi over, I don't need 4, but I want it to be delivered as smoothly and safely as possible.

They are all safe at the power levels they offer.

power: you are good with 3 PSI, so all three tuners work

Safety and smooth delivery: Jb4 is going to be better

now the question is, whether or not it's worth paying double to get a smoother delivery and safety failsafes to protect your car if it overboots or runs lean

Exactly, this is now the conundrum I'm left with.

Let us know which one you end up getting and your feedback; of course

[smithf80]

Some feedback here mike@x-ph.com

So, because I'm nuts, I tried both the JB+ and the Dinantronics Sport.

One thing I'm concerned about, and maybe Dinan_Engineering can chime in here. Their app showed me hit peak boost of like 27psi on a 2nd gear pull. That seems insanely high.

Now, it could be a fluke, admittedly, the app is horrible (sorry Dinan, but I assume you know this considering it's 1 star rated on the App Store), but if it isn't, and that gauge is reliable, that seems way too high. It's in the stock Sport+ mode that it ships in.

That aside, the car does feel like it has a nice, smooth, extra bit of pickup and the install is very easy.

I'd considering upgrading to the DinantronicsX or whatever it's called when it comes out for the G20 based on the performance of the tune, but the app really needs help.

It's probably displaying the chargepipe boost which will spike on upshift

There's no blow off valve in the intake and the system simply closes the throttle and opens the wastegate to prevent overboost when shifting up a gear. The spike is just for a moment and while the excess backpressure isn't "good" for the turbo, it's also part of the design.

The boost its displaying as Knifeedge2k1 noted is the chargepipe boost and not at the manifold. That feauture is more for A/B testing then anything absolute -- at least that's how I view it.

Noted on the app -- the update back this past November helped (purplish splash screen) a bit but all told it still connects to 2 sensors so what it can control/show is minimal and will likely never live up to anyone's expectations.

[helmet91]

Not really sure what else the app needs... It's pretty much set it and forget it for me.

It's more so that it's buggy and the UI is glitchy, not that it is lacking in functionality.

Dinan_Engineering thank you for the reply. Good to know. I'm happy with the performance. Any further updates on the X for these cars?

iOS or Android and what version of OS?

X is coming. About all I can say at the moment.

Latest iOS, latest app version.

The option to select your car/engine always defaults back to N26 which might not matter but it is a glitch, the mode selector sometimes randomly loses showing the current selection as well.

Hrmm. Should always default to whatever was first selected when first paired. Mode selector thing was known in earlier builds but I thought that was resolved. Regardless, will bring it up with the app folks to take a look at.
