Denso SH7058S reflash

[DarkMIKE]

Hi,

I want to ask, if I change some values in my patched ROM file (only some 10-12 values in one table) and after that I will flash it back to my ECU, how this program behaves? I mean it will flash only that changed area of offsets or it will reflash whole ROM file ? Thank you.

Hi,

It should flash only the flash block that has the changed values. So small changes, usually it flashes two blocks, one with changes and second that has checksums.
