Will Vishnu Performance be putting out a flash with the Bavarian Technics Pro?

Title pretty much says it all.

Shiv, does it seems possible to re-write the memory?

No, it is a diagnostic tool, not reprogramming software at this point. Yes, the Pro version allows you to clone modules, But it doesn't include a method to change the files at this time.

But that doesn't men it couldn't be available down the road.

so could one theoretically "backup" their ecu, run a tune (piggy back or flash), then "restore" their ECU when going to the dealer?

Conceptually, yes.

If we can clone - what will stop us from modifying the clone except checksums?

Very interesting development right now!

No. Software doesnt have checksums, or a way to edit maps.

You would first have to understand the structure.

I have first hand experience of this on N54. There are some swedish guys that had the read/write thing and checksum up and running. Problem: they did not fully understand the data and how all parameters was linked to each other. As an example they fialed to remove the infamous lag on 29.2+. Furthermore I think the speed limit was in 4 different parts of the software.

I ended up going back to Procede, realizing that a flash will require a lot from the tuner. This is very complicated to say at least.

Attached is a picture of the software during modification :

Are they using Winols? People make flash tuning far easier than it seems. In a couple of months the right addresses will have gone around the world and your guys will be able to change all they need. Most flash software is pirated from one place or another. Makes it real bad for the guy that sits and figures it all out first, but end of the day someone always knows someone who knows someone who has the software blue paper and thus the chip tuning starts.

Take a stock dump. Then take a "tune" dump from someone with a DINAN. Then run a compare. That will give people an idea of where the appropriate parameters are stored.

Noone is going to make it that easy. Think about the performance software BMW is releasing soon. If someone could simple run stock/tuned compares and do it themselves, why would anyone buy it from BMW? Not gonna happen. BMW and tuners alike have intellectual property to protect.

my friend has software for his s4 that gives him complete control over the ecu.He just copied my brothers giac tune and my friends k04 stage 3 awe tune.The software is out there to do it.

We were messing around with my cousins s4 last night and were adding more timing advance and upped the boost 2psi more.The freaking car was a monster.

the video of the s4 racing a 335 was posted not to long ago.Ari if you see this dont race my cousin,they have tunned his car to smoke yours now,he will run way more boost and run the timing to the max just to berat you lol.The kid has special software that will let him tear apart people ecus and copy/tune them to what ever he wants.

This is the reason shark edit kinda disspared,it would make everyones tunes avail to who ever wanted them.This kid has 4 tuners tunes for s4s that he can easily blast on to any ecu.

IM actually curious if they will put something out for bmws.

Listen I wasnt supposed to tell you,tommy will kill me...Kid his car is a monster with his other ecu....like just as fast as the ko4 car that raced you.

The kid with the ko4 tunned his car up just to smoke you and tommy dosnt care if he blows up his car lol hes already on his second set of turbos.

kid coming to look at my m3 today so I might get a 335 very soon too

I dont understand why someone dosnt put out something that will let you tune your own car.What tune are you gona run ?

You are adding boost and advancing the timing?...

this seems to me why companies like bmw fear tuners...

Why should they,we know what were doing and have no warenty anyways.Sharkedit was going to give us full control of the ecu to do our own tuning.

and yes we were adding timing and boost,the software is sick it has so many things to work with,afr,temps,timing boost,load/rpm ect.

I was just under the impression that adding boost, and adding timing, was a sure fire way to induce knock. Usually upping boost comes with the need to retard timing, unless you are running a much higher octane fuel

but then again, maybe you were, and then thats sweet
