    Default Writing Ecu Denso BW3-8591A-00

    Hello

    Today I am going to program my Ecu BW3-8591A-00 with a clone Ktag (fw version 7.20) .
    These are the steps I have done.
    Protocol -> I have selected -> Jtag renesas and then -> family protocol 646 (being it SH7058)
    Then I have clicked Write and selected the stock bin file and appears this :

    ecu_1.jpg


    I reselected the same bin file and then it appears this:


    ecu_2.jpg


    How can I solve it ?

    I was confident because many say it should work
    Is there anything I can do to try?

    Does it work with Piasini 4.3 ?

    With correct pinout should work. But pinout is not like in Ktag. Because piassini take FWE from ECU not from flasher.
    I dont know is piassini fix checksum but it should.
