Hyundai accent ecu

[japakos]

Hello I'm a newbie here. I'd like some help with my car's ecu. It's a hyundai accent and uses a kefico ecu with the am24f800bb-90si chip. Can you help me out with this? I can read the chip with the willem epprom hardware but I don't know where the maps are for fuel / ignition etc. Can anyone help me with this? I'd really like to make an xdf file in tunerpro but I don't know what hex means what so I'm kinda lost..

Thanks

Why not first posting the binary file here? Will be much better for identifying tables...

You will not only need to identify fuel and ignition tables, but you will need to know how to correct the file checksum(s) after doing the modifications...

And pray you know what you're doing, otherwise a melted piston could be the result.

You say I can't read the epprom right with the willem?
If I can, how will I be able to know what I'm doing ? Is there any xdf for tunerpro so I can tune it myself?
