to have the piece of mind with their warranty and dealer support I say absolutely yes!

Except there's no warranty with this tune

Any eta on the iOS app Dinan?

Other then Apple has it and it is under review no. We don't get much communication from them. They are similar to CARB in that one day it will just be magically approved it seems.

Nothing is changed to the dash. "Race" mode is just the name of the setting on the SPORT device for the app purposes.

So you think this would give similar results as the JB4 tune? I am new to BMW and just getting my car back this week and wanting to add a tune. I was heavily leaning towards the JB4 as it seems to be almost a hands down top pick by most members. I would be very interested in this option. If this didn't give the gains I was looking for, is there a next step I could take to gain additional power?

My understanding is the JB4 is better suited for those with Full Bolt On (FBO) parts. Parts like aftermarket intakes, chargepipes, hi-flo and cat-less downpipes, etc. This, the JB+ quick tuner, and perhaps the JB1 and the AFE Scorcher are better suited for those that have a stock car and want a little more power.

The power is not spotty at all, and install was SO easy. It is very instant and pulls hard (in sport) Comfort still has the facets of being comfort driven, but there is some more umph. Sport mode you can hear the turbos spool quicker, as well as the tq build up. THIS WAS DONE IN SPORT + because I dont have a droid...I cant wait to see the race setting!!

Just so I know Im not going I had my friend drive it, and he was like whoa, there is an immediate difference-- he is my only "car" friend, he is a salesmen at benz and we test drive a lot of the new cars--just drove a new c450 and I want to say that the 335 is faster than this, and has more TQ now--or WE think it feels that way.

GREAT upgrade for 300 bucks. I recommend it. HOWEVER, if you really want to customize your car and get MORE umph out of it, JB4 is the way to go. If you want just a boost controller to make the car even more fun to drive, get this!!!!

I recommend this!

First, a big thanks to Jason@Tischer for the great member support. I ordered mine through him. Instead of writing a new post, I am just going to quote Mike. as I had the same experience. My only addition is that the 3rd gear pull (WOT) is crazy. My tires got lose! Can't wait to try Race Mode once ios app becomes available.

Ok, finally got back to a dyno with cooler temps than back in Aug. Today at dyno time temp was 84 deg and 73% humidity. This is the same dynojet dyno the car was run on with the MPPK. Then it measured 312 HP / 315 TQ





Today the last two runs were done with the Dinan Sport in Race mode with 93 oct fuel. End numbers were 323.7 HP / 342.2 TQ




So at the wheels that's a delta (change) of 11.7 HP / 26.6 TQ for the inquiring minds out there.
Not going to get into crank conversion numbers because that's always a question of the loss factor one chooses to use. The delta is what's important IMO.

Our chart shows peak gains of 19 HP / 34 TRQ (Crank) or 16 HP / 28.9 to the wheels if using the common 15% drivetrain loss. All in all pretty close to reported. I would love to see an overlay between stock (mppk) and the sport if you have the files. On a cursory look it appears there is some very healthy deltas in the lower RPM range.

[Jeff@TopGearSolutions]

I don't even think this car loses 15%. When you guys measure HP, are you using Engine Dyno's?

Would probably better suit Dinan to measure at the wheels on a traditional dyno jet for the sake of transparency.

Drivetrain loss percentages are almost never accurate.

We use our in house DTS engine dyno as well as our Dynapack chassis dyno to measure power.

Drivetrain loss comes down to a lot of factors including drivetrain, transmission, RPM, etc but 15% seems to be the accepted "throw a percentage at a wall" number everyone likes to use. xDrive cars can be over 20% whereas a RWD car in the current F chassis seemingly is about 12-13% in most cases from our testing and correlating back and forth from the engine to the chassis dyno. Not knowing the OP's drivetrain or anything else I simply used the defacto 15%.

That's a fair response.

For those two above I'd have to go back to the shop and get them to overlay them. Next time I'm on that side of the city I'll see what I can do.

Did you do any dyno pulls on the non race mode setting by chance?

Yeah the "first" one was in Sport+, because I had forgot to set it to Race. But that run was kinda nulled IMO because the Dyno Op isn't used to BMWs (it's mainly a GM shop lots of Vettes, Cadillacs, and Camaros). So the actual first try he stomped it and hit kickdown, which of course was no good. Then that "first" run in Sport+ was him adjusting to the feel of the accelerator pedal and me realizing I hadn't set it to Race. It was around 315/330 if my memory serves. But still I think he was getting the feel of things. Plus in the many times I've been to dyno's the 3rd or 4th runs tend to show the best #s. The first run is almost a warmup of sorts.

But if you own a GM I highly recommend their shop for tuning or work. They get great results. There was a beautiful blue Cadillac ATS-V that came off the dyno as I got there.

So if you were just running Sport + due to not having 93 octane available you would make a measly 3hp and 25lb-ft of torque with this vs MPPK?

Opinions out there may vary, but I don't think you'll find too many folks who would take a single first run on a dyno and call that reliable numbers. Yes the 3 HP is no real change over the MPPK dyno (within 1%), but I also wouldn't call a 25lbs TQ increase measly. How many products out there like intakes promote 10-15 HP/TQ increases over stock but don't really provide any change, yet cost at least 300+ dollars ?

The point I was trying to make to you was the only run done in Sport+ was that very first run and I don't think the Op still quite had the feel of dyno'ing a car with kickdown before I switched it to Race. I honestly wouldn't put any great weight in it one way or another. The reason I hesitated to even mention it.


The Dinan Sport seems to provide most of its gain at the lower end of RPM range, in my case it seems to really kick in around 2000-2500 rpms up to about 4500-5000, but after that the feel of the car is about the same as before in Sport+ or Race.

[yoandry]

So, having the mppk, how much hp/tq will i get stacked. Thinking to get this till next year go for fbo/jb4

ha... I meant to say, a measly 3hp ANNNNNNNND....... 25 lb-ft of torque.

[CIWS]

Finally got around to pulling the logged data out of Torque app and graphing it from the last run. (which is the one I have the chart for). Just click on the smaller image and it will pull up the full size.(hyperlinked)




Also I'll post the overlay chart from the last MPPK only run and the Sport+. I think it re-enforces that most of the Pwr/TQ gains are showing in the lower side of the RPM range below 5000rpms.

Thanks for posting this. Looks like we're similarly equipped and although without supporting data my butt-o-meter would agree with your results.

Looks like the iOS Dinantronics Sport App is ready to download in the app store.
