Online hex editor for EEPROM editing/research/comparing

[michbil]

Hello everyone, i want to show you my online hex editing tool hex-works.com (http://hex-works.com/)
Application still in development, but it already helps me to ana1yze unknown EEPROM dumps, calculate mileage, clear airbag crash etc.
In this app you can open several versions of your binary file, compare them,
mark interesting areas with different colors. With inspector tool you can see various data representations and find data areas that protected by checksum, do mathematical expressions on hex data.

This example of simple denso instrument cluster mileage correction with no calculator used, only hex editor tools.

PS: sorry for my bad english.
Any feedback will be welcomed.

it look interesting , but can you tell us litlle bit more ,what kind of clusters eeprom you try .

If you know mileage algorithm, you can correct mileage on 90% of cars on the market. Hex editor is only tool, that allows you to do your work faster.
I use this tool with unknown instrument clusters, peugeot bsi's with unknown version, etc.
For example this is expression for evuation of mileage in opel insignia/chevy cruze/etc

Scaling expression was entered EXPR field of "Inspector" window. In VALUE field you can see actual km's of this vehicle.

Looks very good. A 16bit checksum + xor checksum would be a very helpful feature.

I will add more checksums soon. Updates will be posted in this thread.

Thank you, what sort of dumps do you want to post here? Post some for example.

[michbil]

CHANGELOG:
-- improved clipboard operation.
-- 16bit checksum added.

When I go to the link you provided, the inspector tool does not show up
Is it broken or am I doing something incorrectly?

HELLO BIG MAN, COULD YOU KINDLY TELL ME HOW TO READ SH708X FOR NISSAN NAVARA YD25 2011 AND I CAN DISTINGUISH IMMOBILISER DATA AMONG OTHER FILES?

This is awesome. And would be even cooler if we could add scripts for different cars to the tool!

same here , did you figured out yet ?

[Rajesh diwakar]

can you please suggest me some kind of technique and calculator for this work.
thanks

Hi
Very good initiative. Would it be possible for you to share one or two more examples? Maybe for another radio dump or some dashboard dumps. Or a file where is vin locked and where checksum needs to be adjusted to get it working for some other car. Thanks again
