Work, but where to write errors and calibrations with write-protected memory?

just thinking... calibration of what ?? the dtc are there until turn of the engine. If we go this way....she should fix the car...no getting immo of

Yes loki "If we go this way....she should fix the car...no getting immo" .... this is best way.
But with emulator, simulate signal from UCH without using write-protect eeprom (or lift pin 7 and put 8 on eeprom) .
" the dtc are there until turn of the engine." why do you think so???
If tomorrow comes car with immo off by this way how you will know where the problem?
It's easiest to break something, it's harder to do it!
As colleague peshom said, this is the right way to immo off make and car work fine (you choose how to do it)

because they are, a have made many cars like that. the dtc are there until you turn off the ignition. No one will invest 100 euro for repair car that cost 500 euro.
