Permanence of Canzoomer
 

If I tune AF ratios with Canzoomer, will the settings be permanent or will the stock ECU, over time, change my AF ratios back to stock?

i second the question...also if the ecu does adjust back can it be easily overridden by resetting the ecu the reloading the tuned maps?

it depends on how drastic your changes are. If you do everything all at once the car says wtf, blow me. So do your tuning slowly. There is no reason to reload your map the car isn't going to change that, it has no idea its even there, the map its adjusting is its own.

if you do it correctly and only above 5600 rpms, you will have permanent effects... if you choose not to do this you will have a 1 day effect
