Am about to install my sytsem into my99 and will be putting a heavier battery in too.With my previous cars ive put the alarm into valet mode to disconnect,is there any procedure to follow with scoobys.Also have heard of re-setting ecu,s with different petrols etc and wondered what this involved and the advantages of being able to do this.
Regards Gene

Disconnected my battery the other day (MY99) to fit a new head unit. On reconnection the alarm armed it's self but just disarmed it again with no other problems. Don't know if there is a valet mode or not.
