Hi everybody,

I am about to swap out my stock ECU for a M2 stg III ECU, but I have a few questions. When I disconnect the battery will I need some sort of code to input so that my car and all the accesories start right up again?

I remember reading a thread a long time ago and I remember somebody saying something about not being able to start up the car after doing some work to the car. The thing is I dont remember if that person was trying to install a aftermarket alarm and screwed up the stock alarm in the process, or if they had just disconnected the battery.

But I just wanted to make sure cause I dont want any problems when I swap ECUs.

TIA

 

Disconnect away, nothing will happen to the starting procedure. You'll have to reset your clock, but thats the only thing that you'll need to do differently AFAIK.,

 

Thanks man, I think the problem I am thinking about happens when you are trying to upgrade the stock alarm.

 

It's actually for the stock stereo. There is an anti-theft system that can require a code if it's been disconnected from power (if the feature has been enabled). Mine has never been enabled. It was probably disabled by a dealer long ago (as with most FD's).
