Hi all,

Does anyone know what the function of the ECU MIRROR DEPLOY option is in the later versions of eSys?

Some ECUs have Dual memory identical to each other, One actual and the other is just a MIRROR, so Esys has the feature to flash both memories if you have the token required for it.

so basically it has redundancy if ecu dies during flash?

I think its more for the antituning part maybe? Like in the newer engine control units.

Its anti-modification feature as i understood from my colleague.

I've observed that for TAL calculation there's a checkmark to use Mirroring protocol as default. Should that be unchecked for conventional flashing instead?

Question: The same car, when using e-sys 3.34 there's no Mirror Deploy checkbox, when using e-sys 3.40 there is. So if I use 3.34 for programming, whether the Mirror Deploy procedure is executed?

Thanks for the info guys, really appreciated, I presume this helps if an update fails with remote software upgrade etc

Of course NOT.
