got the apr chip today in my 2000 1.8tq but im not sure if the guy who installed it did a throttle body adjustment and i want to do it just to make sure. my question is do i have to disconnect the ecu to do the TBA or can i just disconnect the battery for 5 minutes and then reconnnect it and do the tba?

 

you can just disconnect the battery, if you have a VAG you can do a TBA through it.
