I just installed a BMS JB Stage 1 on my 2013 328i w/ coded sport AT . It definitely feels faster, but the sport display readings when I'm in sport+ are still still maxing out in the 230-240 hp range.

I'm not looking for accurate numbers outside of a dyno, but are these readouts just for show are are they linked to actual engine data?

[taylor_green]

From what I understand, these numbers are just based on RPM referenced to data BMW installed. It basically knows what power it should be making in x-gear under y-RPMs. It isn't actually reading real time HP or torque.

It's a gimmick!

Piggybacks wont change the sport display , only a properly flash tuned car will.
I have proof mine changed after getting ECU Flash

I wish the gauges would show boost!

I'm with you! And I think most folks would agree too!

The tech at Dinan who installed my" Dinantronics Stage One" told me the sport gauges will not read or show HP and TQ gains because hardware/ software upgrades will not over ride the factory ECU The Diana harness lies to the ECU so it is blind to the changes.
And yes it blows that we don't have a boost gauge .

The factory Sport display is actually pretty accurate. The display reads 2 parameters from the ECU, that is torque and RPM and calculates the HP based on these numbers using a very simple formula. Since MEVD computers used on these cars are full torque based computers, they rely on proper internal torque readings to provide proper fueling. Since the torque model plays such high importance in the fueling calculations, one can see that this data has to be pretty accurate.

Now, once the ECU gets flash tuned, two torque displayed will also increase as long as the tuner properly calibrated the torque model for the reflash, tho the maximum numbers displayed will not be changed unless one spends a lot of time reverse engineering of the computer to find all the functions controlling the sports display. We have successfully done so on the N633tu motors and soon will have identical setup released for N20 and N55.

They are a distraction put there to get you to stare at them while your accelerating so you crash into a light pole and then have to buy another BMW.

Bro. Mine didn't change either. Just got out of the shop. They told me to drive few days see what happens. Did you dunk yours? What was the max hp on your car. ?

With JB4, your torque and HP numbers will not be accurate. JB4 tricks your computer into providing more boost and fuel while maintaining "stock torque" numbers. The only way to make the display show accurate readings is by switching to a proper software re-flash as seen on a video above.

Would Dinan's option display the true values?

[enemigo13]

dinan piggyback or dinan flash tune? If flash tune and tuner would not decalibrate KF_MDIOP (torque/RF conversion) it will show ~correct hp numbers.

I have 320i LCI standard with spec on paper sheet 184HP and 270NM. I've tested yesterday with full throttle, the sport display shows 190-195HP and 300-310NM. Which the correct information, spec on paper sheet or the sport display?

[FSociety]

enemigo13 do you have yours calibrated?

[enemigo13]

I dont have sports displays, they show nothing when I try to code them in.
But I do not decalibrated KFMDIOP table so yes, I see correct torque numbers when I make log with test-o. max you can see with stock software is ~360Nm, now I see ~430Nm.

Greetings, everyone...
First time posting cos I might need someone to bring me back to reality.
Here is the scenario:
2015 320I Xdrive F30-20N-EGW pre LCI. Just messing around and added an Injet CI (I know... does not add HP but the sound is different. Also did a flash tune with Bootmod3 stage 1 (RON)91.... and there we go... the beast is unleashed... That car get to 130mph in no time....{(stock engine did 147)} and I am thinking...? how many HP did we just add? According to the BM3 page, it says.... "N20 (EWG 20i) Stage 1 91 octane: 48%HP / 54%TQ, Ok? 184hp stock + 48%HP= 88.4HP.... SO; 184 = 88= 270...really? Noooo.
The sport display at high RPMs (passing a Ford Mustang at 135) tapped at 275 hp +-5.... is that possible???
PS: my gas millage is down the toilet... but oh well, we only live once....
Did we really added 70 hp?
future plans, add intercooler and a MST turbo inlet.
What are your thoughts? you will not hurt my feelings... just too good to be true.
Thank you, and be safe on the road

I really read that a few times just to understand what you wrote.... the answer is YES.

I'm inclined to say spec on display, simply because BMW is well known for understating their official horsepower numbers. The 328i in independent dyno tests has shown ~225 HP at the rear wheels. That would translate into somewhere between 258 and 270 HP at the crank, assuming a 15-20% loss of power through the drive train.

[Luverse]

when i was running stage 1 BM3 and went WOT, the sport display hit 320hp and 480nm, which i don't believe its true
B48 engine - 330i

[chowser51]

Holy necro thread!

It's not accurate. I have the B46 with BM3 stage 1 93 octane.

This is what it does and I know it's not that high
