I cant read my ECU!?
« on: February 02, 2014, 03:52:36 AM »
Hey Friends!
I have a connection with NefMoto and read ECU info no problem. Using a original HEX-USB Interface with bench harness cable.
I cant read the flash from the ECU. Every time the Message "Reading ECU flash memory failed" is comming. I dont know why?
Using several baudrates without any result. ECU is from a S3 1.8T BAM Engine. (ML906032A 1.8l R4/5VT 0002)
The Memorylayout i have used is the: 29F800BB that must be right!?
ich weiß nicht weiter. please help.

I also tried to read/flash with nefmoto on the bench, with kpw2000 protocol and I have the same problem ''ECU reports that security access request was rejected. '' and ''Reading ECU flash memory failed'' on 032DL 1.8t ecu
I think nefmoto are better for read/flash ecu in car. not sure about this thing. if anybody can confirm ?
In the bench I read/flash with galletto in boot mode with blue KKL ftdi cable.
I have adapted the serial # of the FTDI chip to work with galletto software.
sorry for my english

why do you need nefmoto for a read when you have other software that will work just fine?

Just like the narrowband TT's, nefmoto rarely works. Tony's not around much for support either I'm afraid.
