Title: Launch control add on with and apr tuned b5 s4 mbox Post by: 1slicks4 on August 24, 2014, 06:55:17 PM Has anyone actually done this. I'm needing to add launch control to my car but the car is tuned by apr. Is there any thing I should do prior to attempting to read the flash and change it, or do we think it will be encrypted. Any help would be greatly appreciated.
Thanks in advance. Title: Re: Launch control add on with and apr tuned b5 s4 mbox Post by: ddillenger on August 24, 2014, 07:53:09 PM Has anyone actually done this.

Any help would be greatly appreciated. Thanks in advance. None of this is a good idea. 1. You read an APR flash there is a good chance you lock the ecu down and can't drive the car anymore. 2. You can't modify an APR flash, the files are encrypted, and the checksum routines are altered.

I would have it retuned by someone else but I don't run a meth tune and need the ability to switch my maps easily. I have stock,91,93,100 race tune. With my setup I can run my 100 octane on 91 pump win minimal CF unless it's just 105 degrees outside. Thanks for the advice.

And how they encypt it? I mean they reflash some ecus via OBD and nobody can steal it (or almost nobody). Ok, tuners cant calculate CS, I heard about encryption panel also... I also heard that APR, Revo etc mix code so its impossible to find changes. Is it true?

As for how they encrypt it, that's a conversation best not had. Title: Re: Launch control add on with and apr tuned b5 s4 mbox Post by: Snow Trooper on August 25, 2014, 08:46:47 AM Start from scratch.
Title: Re: Launch control add on with and apr tuned b5 s4 mbox Post by: DNK on August 30, 2015, 03:04:34 AM I have MTM tuned ECU- installed encryption board. But it very easy to download flash bin using OBD connection. If any problem, than try boot mode. All protection is fake.
