Hey guys

Had to swap out the headlight bulbs today as one had popped, ripped the growler out and also the battery so had ample room to work. Anyways disconnecting the battery did reset all my trip settings and radio (sometimes it hasnt). Anyways I hadnt thought about it initially but will i need to load my custom tune back onto the ECU or does it has a little battery of its own and remembered it?

The car does feel the same as before with the tune but then other times doesnt so im really not sure. Oh and for those of you I have spoken to about the ticking noise from my engine is seems to have miraculously disappeared or gotten very quiet I can hardly hear it ever since removing the battery so not sure whats going.

Appreciated the helps guys

Cheers
Phil

lol huh? All good mate, the tune isnt lost as its stored elsewhere
