Today we had a pleasure of Dyno-tuning a fellow forum member's vehicle, ocN55. The vehicle in question was one of the cleanest and most taken care of 2series we had worked with and performed very well at the dyno. This M235i is a stage 2 (aside from turbo upgrade) vehicle with FBO upgrades.

We could not get a real baseline test since the car is already modified, so the base line was performed on JB4 Map0 and original flash with FBO. The run file is named JB4_MAP0_91 on the image. The results came in at 315whp/348ftlb. Numbers are slightly higher then stock M235i since the vehicle comes with FBO.

Second run was performed with JB4 Map 1, original flash and 91 pump gas. The results came in at solid 332whp and 345ftlb. The peak torque stayed the same tho torque at 4K+ was increased. The run file name is JB4_Map1_91.

Third run was performed with JB4 MAP 0 (Disabled), 91 pump gas and our custom flash tune. The results came in at 370whp/412ftlb. The power was achieved with around 13 lb of boost. The peak torque was limited to 412ftlb as the customer is equipped with manual gearbox and 412ftlb is already past the "limits" of the trans and clutch.

The last test was performed with original reflash, JB4 Map 6, and E40 mix. The reason we had to add 4 gallons of E85 (result was around E40) is due to the fact that owner said that Map 6 only runs with E40. The results were very impressive 406whp/433ftlb. The power was achieved using 17lb of boost and keeping AFR at around 13.5:1.

As you can see, the factory Electronic Wastegate limits the boost at 4750rpm. Our stage 2.5 reflash offers waste gate re-calibration and will be part of the package for customers that want to maintain high boost all the way to redline.



We had some more time for one for vehicle and we decided to throw our 2015 550i on the dyno once again. After some more improvements to the torque management and older-school mechanical waste gate, we were able to achieve 529whp/529ftlb. There is still more room for improvements, though 530whp 550i is more then sufficient enough as a daily driver.

Why is the 6 speed limited to 412whp?

People have made more Jam than that on the tranny...

None the less nice numbers.

More of a clutch limitation than a tranny. And HP is irrelevant on the tranny, torque is the concern.

Solid results. A question, though...

Can you help me pick this feature out of the graph, help me understand better what you're saying I should see?

What modifications are required for stage 2.5?

Damn ocN55 Killin it bro! 400/400+ nice work.

From most important to least in my opinion:

Downpipe, Intake, Chargepipe, Intercooler + the tune will make you an FBO car.

I know had to go to SD last minute. We're going to return next week. I'm getting a down pipe to try get as close as I can to your numbers. Looks like I might have to stack a jb4 too. If we lock down next Saturday come by and let me check the ride.

For sure! Next dyno day will be fun

[Bmw doubles]

Yeah, let s run yours one more time I bet your car adapts and has slightly bigger numbers then initial dyno.

Was the stock clutch starting to slip, do you know what they torque they are rated for.?

Sorry meant to say wtq not whp. First time hearing the clutch isnt handling at that force. Is the clutch currenlty slipping? Mileage? Are you going to upgrade the clutch?

Clutch isn't slipping at all, I've ran 475wtq on this clutch when I was running 17psi. We are just trying to be on the safe side. I will not be upgrading the clutch until it goes out, which hopefully won't be for another couple of years.

I feel like you have much higher expectations for this clutch? How much torque are you expecting it to put down my friend?

Gs6-45bz

So it should be 450nm of torque

Haha no no 100% over stock is totally fine. Just the comment regarding the 412 limit wanted to dig further into it. Really the first time i have heard someone look at the clutch before a turbo upgrade

Congrats ocN55. Solid numbers!

ocN55 Alex mentioned that the clutch for the 550 is a direct plug and play for us and obviously holds a lot more tq.

Did you ever Dyno prior to getting flash to see your jb4 numbers?

My 91 octane flash is absolutely incredible. I'm hoping my car can keep running like this without hiccups. This blows away my JB4 tune with the same fuel.

My jb4 numbers are in the OP.

[kd0t]

@ocN55 hey we should do a pull to see the comparison! You're local to me as well
