PhillyfaanM3 Very nice! I have an F31 (2017), and went the smaller dinan box route. Worked great on my older F30, a VW, and now here with some excellent results.

Seems the F31's are getting a lot of attention lately

I love it. Complete jeckyl & hyde. I can drive it like a grocery getter or like I stole it.

Awesome. Glad to hear!

I had a 2015 F31 M-sport with the N20, and got a 2019 330 F31 with the B46 a few weeks ago. The N20 was noisy, but the torque was noticeably better and actually threw me back in the seat much more than the B46. I'm actually a little disappointed in the new car on account of that.

I've been weighing the Elite V2 as a solution to this problem. I'm guessing it won't do much for the lack of low-end torque, but should make up for it in mid-high range power. Your thoughts? I'm not looking to street race, just want to wake this thing up a bit.

Actually, in sport and sport+ this tune is more noticeable down low(1-3 gear)off the line, it starts to level out around 4K RPMS.

The non-linear boost was very noticeable to me on the v1 during aggressive throttle, but I happily accepted it over the stock performance. The v2 doesn't produce the stepping during boost at all. If I didn't know better I'd say there's no tuner installed (if it weren't for the noticeable torque increase)

I have no proof, but it almost feels like the v2 is putting out a little less torque. But it might just be fooling me due to the overall refined acceleration and smoothness during boosting. I've never had a dyno done at any point, so no numbers unfortunately.

The v2 has fewer connection points. The v1 connected to the Intake Camshaft Position Sensor, Manifold Pressure Sensor, Charge Pipe Pressure Sensor, and Fuel Rail Pressure Sensor. The v2 connects to Charge Pipe Pressure Sensor and the Manifold Pressure Sensor. This makes me wonder if some of the smoothness in v2 is due to just letting BMW's ECU make the necessary adjustments instead of trying to control everything? But I'm not an engineer, so all I can do is wonder.

Interesting. I also got my V1 replaced for a V2 due to slight hesitation issues between 2500-3500rpm. The V2 is smoother, but I noticed a situation where the engine runs too rich when cold, and stutters...

Quite honestly I like both, but the V1 had a bit of a kick in the nuts which I miss a little bit... V2 is much more linear & smooth imo.

That's really interesting on your feel of the n20 and b46. I had an n20 in 2014 and it always felt grainy to me. I was pleasantly surprised when the b46 loaners had a fuller sound and smoother pull. They also are trapping slightly stronger than the n20/n26 models in magazine tests.

I'd say go v2 and it should quell any buyers remorse. In my experience, regardless of tuning, piggybacks always give a strong kick down low and taper off up top.

Thanks, all, this gives me confidence.

The V2 is much punchier from a stop than the V1. If you like beating everyone to the next stop light, you'll enjoy the V2.

I'm in midwest/USA and also noticed it occasionally give a little cough when the engine is still cold (on cold days) when I step on it. But for me, the V1 did the same thing, more often, and under a variety of different scenarios and temperatures.

Received and installed yesterday. I've only put about 50 miles on the car, but the difference is mostly imperceptible so far. There were a couple of times where it seemed a bit quicker in comfort mode, but actually slower in sport. I'm wondering if the piggyback and car need a bit of time to adapt to one another.

How long did it take for all of yours to "settle in"?

You should notice a difference immediately. You removed the bypass plug, correct?

Mine didn't honestly feel that much quicker right off the bat. After 150 miles or so it felt like the car adapted better.

[theeaston]

I’m just past 100 miles, and it is definitely improving. A bit difficult to qualify the difference at this point, as it still seems to be learning, but it is getting quicker more rev happy. Definitely not the instantaneous improvement an ECU tune provides, but I’ll take a conservative tune with an eye toward reliability any day after 3 engines in my last Subaru.

[theeaston]

After a couple weeks of driving, I’m happy to report that the tune has definitely made an improvement. Lots more torque in the mid-range while tooling around town. I like it best in comfort mode where the transmission stays in lower gears, making better use of the additional torque.

They did the Dinan on my F31 and F23 as well. Have also done intakes, FMIC, exhaust and wheels / tires. Laura is the best.

They have my BBK for the F31 up there I just need to get the car up there to have it done. I live a mile from Main Line and I drive 22 miles to Thompson. Take that for what it's worth.

EDIT: just to be clear I've had good experience at Main Line (Debbie) and Devon (Eric) and they do stuff like state inspections for me on my cars or actual work on mom car, GF car etc. They're good. Thompson just happens to be great and do everything on my personal cars that aren't stock. Single throat to choke is also a big deal to me, so no matter what is wrong guess what - Laura will deal with it.

I also want to thank the OP. I have a '17 and was delaying based on the early indications of problems with the V1. Good to hear that they have resolved them and it is time I get this installed.

Very curious to see how it's holding up... I have a 2016 328i xDrive Sport Wagon and had a Dinantronics Stage 1 on it for ~6 months before I got a series of the dreaded "Drivetrain Malfunction" warnings. Dinan is in the process of replacing the box & harness, but worried that it's just going to keep happening.

The tune has been good. Going on a 1.5 yrs with it and no issues. The only issue is gas mileage sucks avg 16. But I'm sure that has to do more with where I drive it(stop & go vs highway) and how I drive it( e.g like I stole it).

[BigJoeyVtC23]

Cool, thanks! I'm gonna give mine another try when I get the replacement unit. Agree on gas mileage - the Dinan box makes Sport/Sport+ SO MUCH FUN!
