F10 M5 Flash/DP vs F10 M5 JB4+BCM

[erm324]

Camera car: M5 CP, DCT, JB4+BCM, Map 2 @ 22lbs, otherwise stock

Black car: M5 CP, DCT, DME Tuning Stage 3 flash (23.5lbs), AMS catless downpipes, dodson upgraded clutch packs, JB4+BCM (off)

Both cars on 93 octane pump fuel. Both cars spin on the hit.

Best get that Dodson clutch..

What's the estimated HP & TQ numbers for both cars?

The black car has dynoed ~730rwhp on full kill (racegas, flash/jb4 stack, etc), so I'm assuming it's towards the mid/high 600's on this setup with 23.5lbs and 93 octane.

My car is probably around 630-650rwhp on map 2 and all else stock. The run was pretty accurate based on our expectations going into it.

Impressive. Pardon my ignorance, why would the black car have a flash tune as well as JB4/BCM?

By running a JB4+BCM alone, you are pretty much limited to ~19-20lbs without the CP, and about 22lbs with the CP on pump fuel (fuel trims will be maxed and AFR will run too lean anything higher). With a full flash you can get away with more boost on pump fuel (up to 23.5lbs in this case), and by stacking it with the JB4+BCM you get both the full benefits of the backend flash (fueling changes, speed delimit, cold start delete, CEL delete for downpipes, etc.), while retaining all the features of the JB4+BCM (logging, custom tuning for higher boost racegas maps, etc.).

ACM Stage3 = Upgraded Turbos (Saw ACM post that info on another thread recently)
23psi on Upgraded Turbos much different than on Stock turbos

This black car is a friend of mine he is 100% on stock turbo, stage 3 flash does not mean upgraded turbos.

Next time you guys run I wana get into this orgy.
I'm in NY/NJ

M6 running with Backend Flash + JB4 all else stock.

I had run in the past on Dyno with just map 2 on JB4 and did 620whp.

With my setup of backend + JB4 hoping to be in minimum 650+. Will be dynoying this weekend.


But yea bro to thread jack that M5 is a beast!!! Would love to see it on the 1/4 track though. Mid/low 10s!

So you can run slightly higher boost with CP? Can you elaborate why?

Dyno your car to see if its in your power level before they make you popular on the gram. Lol.

Im guessing you will dyno below 650whp with flash+jb. Arcc aka anes


The blk dynoed at 740/830 to the wheels.

AhhahahahahhHhHHhhHhhHHHhhHhHHhahahhaha
We shall see. May have to pull the trigger on clutch upgrade.

So you forgot to mention what the Stage 3 means?
Everyone else that mentions Stage3 has Turbo/Clutches/Meth involved

The black F10 being spoken of is my former car. Stock turbos, catless downpipes, S3 flash + JB4 and dodson clutches

The black car seems to be pulling pretty hard on the camera car. Is that what 30whp difference looks like?

I'm not so sure, 30whp shouldn't make that much difference.

Yeah ... the black car probably has a better hp/tq curve in the sweet spot rpm ranges vs the cam car.

Hello Erm

I just bought an M5 from 2015 with no CP, does it mean that in my case, the stage 1 JB4 is the best choice since it's I can only run with the map1 without the CP? Do you have a model with the EWG? Because Terry is not sure about this and it seems that's the jb4 may have some issues with the EWG with the standard firware.

Thanks
