F22 / F23 2 Series (2014 - Current)
The 2 Series coupe is the replacement for the E82/E88 1 series coupe. Production starts in November 2013 on the 228i (N20) and M235i (N55) coupes. Look for them in dealerships in February 2014. The convertible F23 2 series will follow in the fall of 2014.

Just ordered: DINANTRONICS Sport Performance Tuner for B58 Engines

http://www.dinancars.com/product/d44...w-b58-engines/
I like the quick and easy installation/removal, no firewall pass-through and the adjustable boost levels via app.
I couldn't resist.

While I am not considering modifications to stock performance, I'll be curious about your impressions and any any tests you perform before/after.

Did Dinan provide you with charts specific to M240i, which already has enhanced output over other B58 models?

Although I do not intend to dyno the car, I will post my 'butt dyno' impressions after install.

I have not seen any Dinan charts for the B58 in our cars, but they have stated in another forum that the claimed gains are on top of whatever the baseline measures are.

Their tests were done on the "Sport+" setting (+3psi); however I will likely use it on the "Sport" setting (+2psi). I really like that it is adjustable via Bluetooth app, so that I can easily try the different settings, from the comfort of my phone.

Haven't received mine yet, but just saw a post in another forum reporting a CEL and error codes after install.
Not happy to see that, but Dinan responded promptly with some reassuring background info.

Pretty much every tuner out there has some report of CELs after installs (Burger NM, etc.). Often times it where a customer runs the tuner on the highest setting and running lower octane gas.

W/ the B58 tuner being new, it may need a tweak or two through Dinan. Could be the difference between 91 and 93 octane gas. Was the guy w/ the problems running 89 octane? Race mode is the highest setting yes? I know on the NM when you set theirs to the highest setting they recommend 100 octane or you'll likely get CEL's.

I wouldn't get too concerned Peter. If you read any threads on piggy-back tuners you'll discover that everyone has a buyer or two w/ issues. Often inexplicable when reading all the positives for each.

Get yours installed and run it in Sport for a few hundred miles (naturally give us your feed-back and "Butt-Dyno" impressions). if no issues, go to Sport + and for the same mileage (reporting back on the difference you feel). If all goes well, test the race mode, or if you are happy w/ Sport + run it there (and just ignore the "race" setting). Betting the car will be plenty fast in Sport + and further betting you'll have zero problems.

I'm holding off for the full dealer installed Dinan Stage 1 tune later this 1st quarter 2017. Dinan is still working on the programming and testing. Hoping it will be trouble free when it hits the dealerships. Since the Stage 1 more modifications to the programing and has full dealership and Dinan support for the length of the warranty, I'm hoping no issues pop up. My plan is to run mine at Sport +. Car is crazy fast now, cannot imagine getting even 30Lb Ft more of torque at the wheels.

Yep. My thoughts as well. And, I always use Top Tier 93 octane fuel.
The car is already FAST as is!. I'll most likely run it in "Sport" (+2psi), or maybe "Sport+" (+3psi), sometimes.
I don't think I'll even try "Race" mode (+4psi).
Mine should arrive one day next week. I'll post my impressions after install.

Until that time...........

BTW, just hit 1200 on mine, half throttle and the car just jumps off the line. Just too much traffic down here to try anything today other than short "blips" here and there. Love the engine note in "sport" too.

WOT from a dead stop (or even a 5 MPH roll) and it's going to be awesome. Wife asked me if I thought we needed anything faster..............I would normally say no, but instead, kept my options open (even if I never need or use the extra HP and torque).

Got it today and installed it and the app on my Android phone w/o issue.
Tried it in -3, 0, +2, and +3 PSI settings. No CELs!
Can't say I feel much of a difference between the settings w/ my butt dyno. I'm going to give it a few days and report back...

Great to hear no CEL's.

I've been reading about different Dinan tunes and perceived results (as I am considering going that route in the near future). Couple of things I'm seeing across the board w/ the Dinan. Now, these reviews and reports are from M235i's cars running various Dinan tunes. Nothing in Stage 1 or 2 is available for the M240i yet. However, if one extrapolates the M235i reports, I'd assume similar results w/ the M240i.

1. Dinan Sport tune seems to show a marked performance gain only when set to "Race".

2. A stage 1 needs to paired w/ a Stage 2 to really see an improvement in performance.

These opinions were not what I was hoping to hear.

I have yet to find a video that shows an M235i dyno'd as stock and then dyno'd w/ a Dinan Stage 1. Having a comparison would show the real gains obtained w/ a Stage 1 tune. Using the published BMW HP number (which are under-rated) and comparing them to dyno'd crank HP numbers doesn't tell us anything really factual. If an M235i (or M240i) published HP numbers are closer to actual WHP (rather than crank HP-which would be significantly higher), then a Dinan Stage 1 tune measured @ the crank) would only be adding a few more HP over stock.

As an example here are actual dyno number from a f56 Mini Cooper S (BMW lite).

F56 Cooper S Stock
(Published Numbers: Crank Horsepower: 189 bhp Crank Torque: 207 ft-lbs)

Actual Dyno results:

Stock:
Wheel Horsepower: 188.06 whp
Wheel Torque: 229.36 ft-lbs
Crank Horsepower: 210.63 bhp
Crank Torque: 256.88 ft-lbs

F56 Cooper S w/ JCW Tuning Kit:
Wheel Horsepower: 206.53 whp
Wheel Torque: 236.99 ft-lbs
Crank Horsepower: 231.31 bhp
Crank Torque: 265.43 ft-lbs

My point...Mini shows 189 HP as the published HP....w/o adding a tuner and reporting Dyno Crank HP it appears you picked up 22 HP, just by cleaning the windows, or adding air to the tires or whatever. So a very mild bump to PSi that would add maybe 8HP, the seller could boast a 30 HP gain based on a dyno run w/ their tuner vs. the published MINI HP numbers.

The 18 HP gain and small torque bump with the JCW tune was very noticeable on my car (Butt Dyno check)

I think that's part of what's going on here.
I think the delta is maybe 10-20 Wheel HP & TQ in the +2 and +3 settings. That difference is VERY hard to feel using a butt dyno.
I used it in +2 today to commute to/from the office and it felt great, no issues. I had it in Sport and Sport transmission. I kept the windows open just so I could listen to it.
Next, I'll switch it to +3 and drive it that way for a while.

This tune is much more subtle than the Stage 1 APR flash tune and intake on my 2012 GTI. That one is 195/204 Wheel HP/TQ stock and vs. 243/310 HP/TQ on the 93 octane program.
It is night and day between stock and tune. It's a different car.

Hoping at +3 you notice a significant performance boost. Hate to think you'd have to run in race to get a noticeable increase.

Let us know.

Also, the car being so new to you (us), perhaps you haven't played enough with it as stock to get accustom to the performance under hard acceleration and other performance feats you normally do in traffic.

I'm just now starting to get into seeing what my car will do stock. I can tell a big difference in response when in comfort mode and tranny in drive and just moving the tranny to M/S while still in comfort mode. Virtually zero lag or balking.

Sport and M/S the car is really responsive, so much so I haven't been able to actually see its capabilities. It is scary fast in traffic and a sure "ticket-getter" if I'm not careful. I'd need some time on some country roads w/ no traffic (or police) to see what it will do. Or at least spend a few months with it as is to play with the different modes and get accustom to the cars limits and what to expect.

If I threw an tuner on it, I'd really have no idea what benefits I got or didn't.

Fortunately w/ my Mini I drove it for a few months and knew how the car performed in all modes. Hard throttle off the line or from a 10-20MPH punch. When the JCW tune was installed, I saw a noticeable improvement immediately. Again, only because I spent time with it stock and played with it a lot.

I have to do more of that w/ mine to get used to it. As it is, I'm in awe every time I hit the accelerator. I have still not floored the car, best I've done is 2/3rds in traffic and it was pretty eye-opening.
