Xcede vs JB4 on same car, same dyno

[S1NGH 911]

:fencelook: I'll just sit in the corner and be happy with my Cobb :crazylaugh:

Ask Shermantor to xcede your Miellie Cobb...:roflol:


Sorry I am fudging around to much now...

We are the only authorised BMW cobb tuner in Africa. We can make custom maps for Cobb & have the Cobb Accesstuner Pro software.

Well done Shermanator! You sir are a tuning God! I am selling jb4 and integrated meth to put one of your flashes on...terry burger is a dweeb compared to you..

Somebody asked Terry this week if he can tune his Vargas Stage 2+ & this is what Terry said:

There will be JB4 firmware changes needed for these turbos. So anyone running them be sure to stay in contact with me via email with current logs, etc, and I can help you out on that front.

Al he does is create a device & firmware. Terry himself says he's not a tuner & a piggyback is not a "tune". It works & it works pretty well at getting the boost up. And we sell a lot of them. But it's not a tune & Terry is not a tuner. These are his own words.

Great work :thumbs:

Would like to see jb4 with backend flash vs Xcede

Ok explain why please? This car has the following hardware:

1. Downpipe

Wht settings are required in a back end flash for a downpipe?

---

jb4 on its own is a very conservative tune add the backend flash and then you can compare apples with apples
a flashed ecu with a flashed ecu

Everyone jumping on the "let's compare to backend flash" bandwagon.

Can you tell me what a back end flash is in what situation is it required?

Also why do you need it to compare apples to apples? A flash tune doesn't need a "front-end box" to make 402 whp.

Did someone say Apples :grin:

 

[M3_devil]

If we keep this thread clean then it will be one of the most informative posts for the n54 guys.

well done so far guys.

 

[Kish2604]

Welcome back Shix... Good to know you were in there somewhere! :rollsmile:

The new flash logic available to the likes of Sherwin have really opened up tbe limits on the n54, however to compare a jb piggy alone without corresponding back end is also not a level playing field. I am lucky enough to have a custom back end that has the same "logic" applied to tbe tables that Sherwin is using and to be honest my car in full weight doesn't fail to scare the bejesus out of me..

I am still keen to take on the challenge in Durban..

Kish, why does a JB need a back end flash? Doesn't this box attenuating the voltage on the MAP sensors do enough for a good "tune"?

BTW, a car with just downpipe doesn't need a back end flash. But load it & bring. This isn't a trick. I want to do this.

Shermanator...

In response to your post, I did this with just jb4, octane and cheap downpipes in October 2013, 2 months after getting my car...no meth, cooler, backend flash, intakes or even tailpipes at Autotrix. So no! A back end flash is not needed for big power.. But it does make the jb4 experience a more pleasurable one.

There we have it :chef:

Apples with Apples

 

[Chavoos]

I've had the Xcede flash tune on my car prior to this new tuning improvements and it ran great. Always wanted the JB4 functionality with an Xcede option.
Wasn't possible and went JB4 route.
Sherwin, guys are loading custom backend flashes and using JB4 functionality. Is it not possible to combine the best of both worlds and load an Xcede backend flash whilst maintaining the JB4 functionality?

Hi guys an N54 that makes 300kw at Stars wll make around 270kw at KAR. Ask me how I know?

Because I owned a 335i from 2007. I have dyno'd 4 N54's at KAR & Stars & the difference is 10%.

Apples with Apples

Sea-level is apples? 5500ft elevation is oranges.

That's 270kw at KAR.

A back end flash is not needed for big power.

Do you understand what a back end flash is for?

yes I do know what a backend flash is as iam currently busy fine tuning a custom flash for my car using tuner pro

 

[Sherwin@xcede]

Ok I'm happy for you & I wish you well. When you tune an N54 with just downpipes, tell me what changes you will make in the back end flash? And what power that will yield on a car with just downpipes.

 

[Kish2604]

At this point I won't stoop to your level and get into a slinging match with you..

You asked, and I quoted your question in my response...

Kish, why does a JB need a back end flash? Doesn't this box attenuating the voltage on the MAP sensors do enough for a good "tune"?

I responded with a valid dyno run showing what a Jb and dp did last year...at this point you want to start being the bigger person and tell me how long you have owned n54's, blah blah blah... Graciousness is not your strong point.

You asked a question and I proved it.. Get over it...:blueCry:

 

[hoosain]

you should know sherwin

 

[Sherwin@xcede]

How is that valid if it's at sea-level buddy. Please tell me you have enough brain cells to compute that. Please tell me you understand or don't respond to my thread of a car with JB at altitude which now makes much more power with a flash. This isn't about your car at sea-level. PLease tell me you understand this wasn't done at stars.

at this point you want to start being the bigger person and tell me how long you have owned n54's, blah blah blah... Graciousness is not your strong point.

And comprehension isn't yours. I'm not gracious because you are a fan boy. Get over it & supply a car at altitude, or stay out of the thread if you don't have altitude specific input.

---

you should know sherwin

Of course I know. I've been tuning these cars from 2007 (sorry Kish, I shouldn't have mentioned that but it happens to be the case).

My question is what power will that make (over & above what the JB does) for a car with downpipes. Let me be more specific. JB has a "map" for a catless downpipe which you can switch to from your steering wheel. So why do you need to use a flash tune to make changes for the downpipe? Are you targeting more load, more advance, or what & doesn't the JB "map" for the DP already do that?

 

[Kish2604]

Yah you right... Intelligence isn't mine...
:clapper::clapper::clapper:

It must annoy the shit out of you that the n54 tuning has gone so open source, in fact it was arrogant people like you and Shiv(Vishnu)that got people who are smarter than me to write fool proof programmes to read and flash the n54 so that even a monkey like me can use it...

So much so I can get similar results as you can, and I am not even a high level tuner!

Doesn't annoy me at all. You haven't beaten 296kw at altitude with just a DP. That's a record my friend. Maybe if you beat it, it might annoy me but probably not. It's pretty hard to get annoyed if you currently hold the record.

So yeah right now you haven't beaten anything up here. Cheers till you bring a car to a dyno up here.

Kish, you make 323kw on the wheels and this is what you run:

02/11/2014 12:58:02 PM Right 6B27, 12.498 187.08 0.731 NO 2.0004

I don't know if you understand drag racing & the significance of exit speed in relation to horsepower. But first want to confirm the above. I's sure you are going to say that there was something wrong with the car, please don't use the driver as the excuse because I am going to delve into the exit speed not the ET.

 

[Kish2604]

It's a sad time isn't it...

I got no excuses for my poor exit speed and time by your standards...monkey needs to learn to drag race!
