Hello im Tommy from Sweden
Anyone who wants to take a look at my hex file

How do i put up the file here?

How do i take out the hex files from winols so i can program my chip?
it doesn't change the hex code that i`m working on even when i save.
I think i have found two torque curves probably one is for the fault codes.
What happens if i change wrong hex code, do i burn my ecu or it just won´t start

You are probably using demo version of the program.
Changing wrong hex code will only block the ECU.

I changed in the hex code that i think is the torque map, there are 3 maps that looks quite the same so i changed the 2 ones
and the car runs bad and the edc lamp flashes,
what about checksums are they important, or are they not in use in older cars like Scania 143 1993

Older ECUs do not need checksums to work.
Read the DTC codes and then you can see where is you problem.

iI get internal edc fault code,when i have changed 1 number in something that looks like a map.
