hello everyone ..
a freind of mine had his ecm destroyed during tuning when the battery went down , he bought new ecm and it came with no data inside
its jeep wrangler 2013
how can we flash it? it has no date inside
I've never been in a position where I've needed to start with a brand new factory ECU. It's possible that to get you up and running the ECM will need to be originally flashed by a factory dealer ship. Have you attempted to perform a write to the ECM yet?
there is a guy doing this not a dealership ..i was wondering how!
I'm not too sure exactly what you want to know? Depending on the reflashing software it may be possible to write to a brand new ECU but otherwise you may need to take the ECU to a dealership and have it flashed by them initially before changes can be made. Often the security imobiliser will need to be setup when you're swapping a new ECU into a car.
