Simtec 71, Hybrid ECU - how to read/write flash?

**Pali33** · 8th December, 2015, 10:46 PM

Hello all,
is there any possibility to read/write flash on this ECU: ?
Opel Simtec 71

Any advice to some flash-tool is welcome. I found only Abrites, but there i'm not sure, if it can do this job (and abrites is prety expensive)

Galetto2 works 100% with this ecu.

@cristi_bv
are you sure that Galleto2 works? I have Galleto2 and there is no Simtec71. Only Simtec 71.1

@soxten
CarProg can read only eeprom. I need r/w flash .

yes,i have done a few.it read's/writes without problem.For what you need to flash ecu?

Galleto2 read only maps (only 23kB).
I need read/write whole flash content.

Know anybody some tool, which can read/write whole flash content of Simtec71? (not only maps (23kB), as Galleto)

Try I/O Terminal tool.

I/O Terminal is the right tool for this if you want to read it

thanks for tip,
can you (or somebody else) confirm, that I/O Terminal read full flash, not only 23kB ?

Cristi_bv... What do you mean by saying that you have flashed theese ecus with galletto? Need a boot mode to make a full (256kb) flash, not 24kb as galletto and mpps and abrites does...i've made a boot mode on the hybrid simtec 71, but it acts strange. Digferent than simtec 71.6. on 71.6 it does enter in boot mode, but in hybrid 71 or 71.5 it does nothing when you read it with gal... Practically, it enters in boot mode, but when you try to read c167 - boot mode, it does not recognize it...
