Bmw M6 Dyno (Backend tune + Jb4)

[ARC550]

2013 Bmw M6

Mods:
K&N air filter
Enzo Performance custom backend flash
Burger tuning Jb4+ BCM

All runs where done in 5th gear.
11 gallons of 93 octane
2.5 gallons of E85


First off thanks to Enzo and BMS for all the back and forth logging and support.

World Record?.. So far haven't seen higher on only Ecu modified.

All Dyno runs where on a dynojet with STD-5. You can see it in the videos. This is to cancel out those batch of questions.

Temperature: 96 Degrees with 65% Humidity

93 Octane only Pull breakdowns:

93 Octane: 22psi: 641-650
93 Octane: 23psi: 650ish
93 Octane:24 psi: 650ish

Car is pretty much limited to power without additional Fueling(consistent in all runs on 93) . The numbers would easily have been higher but temps outside where 96 Degrees with 65% humidity.

I let the car cool off for about 30 Minutes. I poured into my Half a tank of 93 octane 2.5 Gallons of E85. I let the car idle for 5 minutes, reved it a few times and shut it off to cool some more with fans blowing every which way for another 20 minutes. This is the First time I tried E85 and wanted to see if their was an actual power gain as almost everyone claims Ms109 is better.


E85 Pull breakdown (11 gallons 93 with 2.5 gallons of E85):

- 25 psi(1st pull) - 692whp
- cool off 15 minutes
- 25 psi (2nd pull) - 715whp
- 26 psi (1st pull) - 732whp
- cool off 15 minutes
- 26psi (2nd pull) - 738whp

Car was adjusting to the E85 after every pull. It was getting stronger and stronger. I had stock clutch slip once during the 25psi pull. Other then that pretty consistent.

I am sure if I cranked boost higher and let car adapt 750whp would have been capable.

In short 25psi is more then enough with a pinch of E85 on a stock car. Can't go wrong!

Car was a bit lean (air fuel) as it started to adapt it started to smooth out. The E85 was foreign to my car lol never tried it before. In short it works! 60-80whp with race gas is epic.

I will be testing out his new found power at the track in a week or so and shooting for 10s.

Interesting. I'd bin the K&N though as the oil seeps through over time and fucks the MAFs, ask me how I know!
My tuner was not happy that I had fitted them as he had a pile of them in the corner of the workshop from other modern bi turbo cars which they had removed and gone back to stock dry filters.

This is really interesting thank you.
Was your car tuned to specifically run on E85 or can you run it straight up?
Is the ratio approx 80% normal fuel : 20% e85
Do you know what the standard boost is?

Bmw said this "Plus E85 is a no go zone for BMW. Ross, our master tech, told me you won?t get any more power from e85. In fact probably less with the type of turbos on the car."

1st off alll o giant 80whp with E85
2nd nope. Everything is fully stock just a backend flash and a Jb4 to control boost. Nothing else done to the car mechanically

This is 11 gallons of 93 with 2.5 gallons of E85

Ok cool, I didn't realise you could have the ecu flash and jb4 running same time. I thought they both did the same thing. If it's not too much trouble could you point me in right direction of the jb4 as there are a few different options no?
And you can set the jb4 to increase the boost only - so it won't alter the custom maps?

I've already flashed my ecu but only got 11% more power (with akrapovic and catted downpipes)... Must be low boost. How much extra power did you get from your ecu flash/tune? And do you know what the boost levels are without the jb4?

To many variables.

What flash do you have? And since you have a flash you need the Jb4 + BCM. Essentially all the jb4 would do is monitor and control boost while the backend flash took care of everything else in between.

Insane numbers. Cant wait to get my downpipes installed and tune from Enzo.
