Sorry if this is a silly question. Does changing your battery reset your PFC? Or does everything remain the same after I swap in my new battery and start the car up?

The map does not go away but the PowerFC learning may be reset which isn't a big deal.

I was also wondering if I will loose my past year's map with my battery out while doing my rebuild!

Not that the map will be correct anymore due to porting, but at least I know it should idle decent enouph to work with it.

Thanks!

You will not lose your map because the PFC saves them into memory.

And to confirm is this the correct way to re-learn the idle?

Start Car, let it idle for approx 10 minutes before doing anything
Turn on air-con, let it readjust its idle and wait about 10 minutes
Turn on defroster (full heat), let it readjust its idle and wait about 10 minutes

Afterwards I can drive the car.

I thought it was rear defroster before AC but let the experts chime in!

Order doesn't really matter. They're 3 separate settings. IMO, if your car is running fine after battery change, don't bother going through the 30 minute procedure.
