Nistune Forums

I've noticed that my latest files start with FFs and have FFs in 95% of the file. Does it sound OK? I didn't notice when they became corrupted...

It looks like what you did from the email was resync into a blank image (which is full of FFs initially)

If you load a factory image first into NIStune, you can then resync the maps into that and then save it

If you want to burn an EPROM then
(a) use the first half of the image (saves as 32K ROM but the S13 CA18 uses a 16K ROM chip)

(b) or use a 16K EPROM address file, load the factory ROM file and then your other file with the maps only. Then copy the maps across

Yes I read from ECU into just-loaded Nistune. I thought Nistune reads/writes whole 32Kb, but now I understand that it transfers only those areas that are defined in address file, is that correct?

Thats correct

Takes too long to do a full rom download (with normal consult anyway) so we only sync the maps since thats all you need to edit
