**javiere** · 16th November, 2018, 05:41 PM

hi
know of a programmer who reads and writes one of these ecus of bombs vp30 vp44 ?
0281010888 or 0281010480

I'm not interested in repairing a transistor. just read and write the flash.
but I do not know the protocol or the file size ..

Hi

I can read the memory up to 0000-9FFF.
Write only the BOSCH EPS944 knows.

In EEPROM I can write and read 00-BF.
The EEPROM can not write and read C0-FF.

The programmer is a self-made software and hardware.

which its your concret problem why you need to read firmware of psg 5

**Pepita** · 23rd November, 2018, 01:00 PM

I'm sorry, I can not speak English, I'm writing a google translator.

I do not have EPS815, I have never used it.
I wrote the software to read PSG5.

friend. i you have vcm you can adapt very easy why you need such tool

**Pepita** · 23rd November, 2018, 01:20 PM

I'm improving PSG5.
I had to write software so I could try it after repair without EPS815.
On a desktop I can test Opel, Ford (I can turn the immo off), BMW, AUDI.

I want to make a flash copy from one ECU to another.

it's possible?

someone knows how to do ?

**Pepita** · 19th December, 2018, 07:14 AM

PSG5 does not have flash memory.
Pocessor 87C196 OTPROM. I do not know how to write.
EEPROM 256 bytes.

Hello, my dear collegues. Until somebody find a solution for that, the cars having psg5 will be all in the scrapyard. Is a topic here, on DK, only for vp44 pumps and how to read eeproms. But nobody figgred out how to rewrite them yet.
