E-Sys Version

PFC · 08-13-2017, 07:09 AM

My car will be going in for its first service soon. I have made some changes to it (stop/start disabled, LED bulbs and fogs).

If they update the software at the dealer and overwrite my changes can I use my existing E-Sys 3.27.1 to re-code or should I use the latest version?

You can continue use your existing version of E-Sys.
But you will need the latest psdzdata if the dealer will update your car.

OK, thank you.

No reason to update to 3.30.1 unless you are using Pro Launcher or are programming. E-sys 3.27.1 still works the best.

So if they do update and I have to re code my changes I should only need to replace psdzdata with the latest version before connecting to the car?

You update out of necessity. Computer PSdZ just must be > vehicle I-Step.
