I need to remove the battery and do some electric work which will last much over 15min and i know the ecu is going to reset (whopty f**** do right). Question is, will the Vafc reset its settings from having no power 'cause i dont want to have to pay another $130 to get the car re-dynotuned.

helps appreciated. ty!




*btw i changed the batter not long ago and the vafc didnt reset, but the car must've been out of power for like 2minutes.

 

i dont think it will.....not sure i dont own one tho,.

 

I don't know about the first version, but the second version retains all the information even when the power is disconnected.

 

1st gen VAFC saves all the settings. Think about it. when you shut off the engine, there is no power to it. Unhooking the battery doesn't do anything different.

 

sounds like you have a doubt there.... seems like i'll have to write down all the settings and reprogram them IF it resets...but then there's a lot of menus and i might miss something =

anyone 100% perfectly absolutely positively and utterly sure?

 

there is no doubt there.

IF the vafc only has 1 power wire cutting the power wont reset any thing. like nsxnext said, it would be just like turning the car off over night

 

I am 100% absolutely certain that the V-AFC II will not lose the settings when the battery is disconnected. I can't imagine why the original V-AFC will be any different.

IBre-dyno

j/k it holds the settings, at least the one in my civic always did..

 

etxx care to share your vafc settings =]

 

^^sure what would you like to see

fttym, i can't exactly tell which of the 300wire coming in/out of the vafc and ecu is a power but i do understand what you mean if it only had 1.

i'm calling apexi!!

 

I had my battery un-hooked for at least 2 hours and the V-AFC did not need to be re-set so don't worry about it or call Apexi if need be

Sorry ... but nothing to do with 2nd gen TL. Belongs in off-topic > car talk. Thread closed.
