AUD-Support of ECUflash ?

Postby Jochen_145 » Sun Sep 30, 2012 12:45 am

Hey,

I found here in this forum and in other that ECUFlash should be able to support AUD-port readout (bit-bang-mode ?!)
with a spezial interface..

What´s about this ?
Is the support implementated in all ECUFlash versions or only in "special" ones ?
What kind of interface is needes, do someone got a wireing of it ?

How to activate the AUD-reading in ECUFlash and is it possible to scale the readout size ?

If ECUFlash is able to support AUD-readout, I thing it will be a big advantage to the SW.

Every hints to "easy-AUD-solutions" etc. are wellcome :!:

found that bitbang-mode of FTDI chip makes it work as a 8bit bi directional bus.

So IMO it will work like the arduino- or propellor board solutions explained on active board

AUD mode is disabled at Subaru Denso ecu's.
That means this backdoor is locked.
Anyway you are welcome...

Don´t know about that..
PIASINI and some other read via AUD the Subaru Denso ECUs.
Even china clone reads AUD, but not stable so you get a read-out wiht some crap values and so bad checksum
That means this backdoor is locked.

Maybe this is only on some special ECUs ?

It may be.
I personnally have not seen completely unlocked yet. Just analyze the code already uploaded.

Piasini needs a bridge between a connection, with I just know by picture and GND.

Without this bridge, the read-out will not work.
Maybe this "short circle" the locked backdoor ?

У тебя осталась картинка ЭБУ, который был залочен? Мне еще не один блок не попадался залоченный.

Do you have any pictures of the ecu locked?
I have not seen any locked yet.


MY04 JDM Legacy dual AVCS ecu. I suspect ADM dual AVCS versions use the same code.

Just analize or download the code into any SH7055 ecu.
Have fun.

AUD readable after being enabled inside the code.
