YOU NEED THE FULL 512KB BINARY FOR THIS, CALIBRATION OR TUNE FILE WILL NOT WORK!
This modification works for software versions 430037, 430056, 430066 & 430069. If the demand is high enough, I can take a look at others as well.
To determine the version you have, open the binary and look at 0x70040, it starts with "ca and folled by the version string.
The EWS delete patches are split into three parts:
Jump out normal EWS handling subroutine
EWS bypass program code
DTC suppresion (c_abc_inc_tout_imob)
It ONLY works if you patch all three locations in your file and only if you have matching original data.
