I was just curious, after you've spent all the time tuning your VAFC and have inputted the settings best for your car, does the VAFC clear itself whenever you reset your ECU by pulling the negative battery cable? Or does it retain these settings even after resetting the ECU by pulling the negative battery cable?

Anybody have any personal experience with this? Thanks guys!

 

I would guess that it retains it's settings since the settings are stored on the VAFC and not the ECU.

 

they stay in the VAFC memory. I know because I have resetted my ECU after tuning my car.
