Title: Cannot read Flash, Security access denied due to invalid key ? Post by: RC200 on February 25, 2020, 08:28:27 AM What's wrong ? What does it mean ?
I just wanted to read the Flash. I first attempted 29F400 and then 29F800BB (didn't remember the right size). Title: Re: Cannot read Flash, Security access denied due to invalid key ? Post by: nyet on February 25, 2020, 09:48:05 AM Not stock or immo

Post by: RC200 on February 25, 2020, 10:06:27 AM Not stock or immo So, what is the counter measure ? I probably have Immo2 (euro S4). Not stock for sure (MRC tune from previous owner). So, non-stock ECUs cannot be read ? Title: Re: Cannot read Flash, Security access denied due to invalid key ? Post by: d3irb on February 25, 2020, 10:35:16 AM Touching non-stock ECUs with tools is dangerous, especially dangerous outside of bootmode. You have no idea what the tuner patched in over the normal read/write routines - you're lucky they seem to have adjusted the seed/key rather than something worse. If you are interested in making your own tune, verify that the hardware is stock and flash to a stock BIN via boot mode, then start over.

What does this mean? Title: Re: Cannot read Flash, Security access denied due to invalid key ? Post by: RC200 on February 25, 2020, 10:40:45 AM Your sig says "MRC map" What does this mean? In Europe, MRC is a tuner. http://www.mrctuning.com/ My car has been "adapted" to K04, 750cc and probably boost by the previous owner.

I know who MRC is :) You're going to want to rethink whatever it is you are trying to do. Title: Re: Cannot read Flash, Security access denied due to invalid key ?

I have free engineering time and I could enhance my E85 fueling more accurately. Maybe the best way is to purchase a H or M box and to start from scratch and working on the bench, disabling Immo first (I mean from a stock bin).

Also IMMO disable isn't required if you just have it working properly. |
