Hello I post this topic because for me and some other noobs like me. I like to know what is good to do just before write the chip on ecu just for safety like connect the charger to Car for good voltage and other things like that.Let the GURU in chiptuning to share their knowledge.Thanks!

some cars need special attention - that is learned from experience ... first of all don't flash anything on a car that you don't have the knowledge and tools to revive if something goes wrong .... second car connected to charger and laptop connected to charger just to be on the safe side :)
